An example: you have 10 different files in Azure Blob Storage you want to copy to 10 respective tables in Azure SQL DB. Since there can be In other cases, workflows need to execute a certain cleanup action independently of the result of the execution. The Copy behaviour is set to Merge files, because the source may pick up multiple files, but the sink will only be one single file. When assigning parameter values, you can use either the pipeline expression language or the data flow expression language based on spark types. Instead of creating 20 datasets (10 for Blob and 10 for SQL DB), you create 2: one dataset for Blob with parameters on the file path and file name, and 1 for the SQL table with parameters on the table name and the schema name. However! By clicking Post Your Answer, you agree to our terms of service and acknowledge that you have read and understand our privacy policy and code of conduct. Tip: Consider validation if you are allowing dynamic expressions in your workflows to ensure no malicious code can Azure data factory: pass where clause as a string to dynamic query with quotes. business value or hold domain semantics. Im going to change sets to be a generic dataset instead. A crucial part is to creating this connection to the Blob store is the azure-storage library. Return an array that contains substrings, separated by commas, from a larger string based on a specified delimiter character in the original string. There might be requirements where we want to connect different databases from the same logical server or different database servers themselves. runnableWorkflowConfiguration object holds all data needed to execute a workflow, including all activities, input To avoid this and recover gracefully, we provided a way to handle workflow timeouts and Thanks for your post Koen, provided by the DTFx framework. On the tab Connection. The closure step or closure activity is a normal workflow activity. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. workflow step to subsequent steps. example, in order to check method calls the following snippet can be helpful. In this post we have shown how we built a workflow engine on top of DTFx and tailored it to our needs. Is there anything that I am missing here? Return an array from a single specified input. Subtract a number of time units from a timestamp. The Copy Data activity in Azure Data Factory/Synapse Analytics allows data to be moved from a source table to sink destination in parallel, allowing for better performance versus single threaded operations. Did I understand correctly that Copy Activity would not work for unstructured data like JSON files ? Step 4: Create dataset sinkRepeat steps 13, but now create a sink dataset, representing the target location for your file. TL;DR A few simple useful techniques that can be applied in Data Factory and Databricks to make your data pipelines a bit more dynamic for reusability. Return the number of items in a string or array. I should probably have picked a different example Anyway!). Notice that you have to publish the pipeline first, thats because weve enabled source control: That opens the edit trigger pane so you can set the parameter value: Finally, you can pass a parameter value when using the execute pipeline activity: To summarize all of this, parameters are passed in one direction. Return the product from multiplying two numbers. Building a safer community: Announcing our new Code of Conduct, Balancing a PhD program with a startup career (Ep. Azure Tutorials frequently publishes tutorials, best practices, insights or updates about Azure Services, to contribute to the Azure Community. But first, lets take a step back and discuss why we want to build dynamic pipelines at all. This ensures that the value of pipeline variable input_value is passed to the notebook. Mapping data flows in Azure Data Factory and Synapse pipelines support the use of parameters. Return characters from a string, starting from the specified position. You read the metadata, loop over it and inside the loop you have a Copy Activity copying data from Blob to SQL. With a dynamic - or generic - dataset, you can use it inside a ForEach loop and then loop over metadata which will populate the values of the parameter. When you click Pipeline expression, a side-nav will open allowing you to enter an expression using the expression builder. Besides the fact that operators often you can better encapsulate changes. Developers can think of it as a try/finally construct. For the sink, we have the following configuration: The layer, file name and subject parameters are passed, which results in a full file path of the following format: mycontainer/clean/subjectname/subject.csv. your end-users and start with those. of the OrchestrationContext. If partitions are defined on your source table, you are good to go! Return the binary version for a base64-encoded string. The left() function is used trim off additional digits. With a dynamic or generic dataset, you can use it inside a ForEach loop and then loop over metadata which will populate the values of the parameter. Boom, youre done. engines we selected the Durable Task Framework (DTFx) due to its performance This represents the sourcefile involved in your copy activity. Return the day of the week component from a timestamp. To learn more, see our tips on writing great answers. Comments are closed. In the side-nav, enter a name, select a data type, and specify the value of your parameter. Return a string that replaces escape characters with decoded versions. For example, if you received the filename via a trigger event you can refer to the triggerFileName as, Or, if you defined the container name in a pipeline variable called source_container, you can refer to this variable as. In the last mini-series inside the series (), we will go through how to build dynamic pipelines in Azure Data Factory. ADF will create the tables for you in the Azure SQL DB. In this post, we looked at parameters, expressions, and functions. The fact Combine two or more strings, and return the combined string. compile-time vs runtime. APPLIES TO: So far, we have hardcoded the values for each of these files in our example datasets and pipelines. Lets see how we can use this in a pipeline. Your goal is to deliver business value. Return the base64-encoded version for a string. custom validation based on business rules (using FluentValidation in C#). if a closure activity was provided (by the way, its optional) and if so, we schedule it to execute on the same instance Why does bunched up aluminum foil become so extremely hard to compress? Check whether a string starts with a specific substring. Return an integer array that starts from a specified integer. Dynamic range partitions for meta-data driven pipeline Solution Overview The Data Factory in my demo environment uses Azure SQL DB as the source. The first way is to use string concatenation. Select New to generate a new parameter. By parameterizing resources, you can reuse them with different values each time. Remove items from the front of a collection, and return. You cannot use - in the parameter name. In this blog we show how to configure dynamic source and sink directories for your Data Factory workflows, enabling you to copy data from and to dynamically defined directories. We will setup a pipeline with two pipeline variables, and three activities. We hope this information will be helpful if you are Check whether at least one expression is true. provided externally at execution time or values generated while running the workflow e.g., the current value of a PLC We can think of it as You can call functions within expressions. Tip: Consider validating as early as possible to give feedback to end-users. Can I infer that Schrdinger's cat is dead without opening the box, if I wait a thousand years? As we saw previously, the workflow definition time is not the same as the workflow execution time. Concat Azure Data Factory Pipeline parameters in SQL Query. Instead of passing in themes.csv, we need to pass in just themes. For example, the following content in content editor is a string interpolation with two expression functions. branching statements, among others, that dictate how a workflow would execute. Stay tuned for weekly blog updates and follow us if you are interested!https://www.linkedin.com/company/azure-tutorials. DynamicExpressionVisitor. Return items from the front of a collection. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Having a workflow running for a long time without any response rev2023.6.2.43474. Once the tables are created, you can change to a TRUNCATE TABLE statement for the next pipeline runs: Again, no mapping is defined. The execution plan of a workflow could be influenced by input parameters on execution time or by values that were Return the timestamp as a string in optional format. Convert a timestamp from the source time zone to Universal Time Coordinated (UTC). The workflows we are dealing with have (write) access to machines on the factory floor, so validation of dynamic expressions and the workflow as a whole is crucial to ensure safety and communicate issues earlier to factory . Here we will fetch the result from the Databricks notebook activity and assign it to the pipeline variable output_value. Reports for special groups and item family were also added and item family and special groups were added as selection parameters in dynamic . Not at all ). In the Lookup Output, you can see the UpperBound and LowerBound return values: 4. In this post, we will look at parameters, expressions, and functions. You will need this name later when you fetch the notebook output in your pipeline. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. (Trust me. First we create two pipeline variables input_value and output_value, both of type String: We add 3 activities to the pipeline; Set variable, Notebook, and Set variable. In the HTTP dataset, change the relative URL: In the ADLS dataset, change the file path: Now you can use themes or sets or colors or parts in the pipeline, and those values will be passed into both the source and sink datasets. An example: you have 10 different files in Azure Blob Storage you want to copy to 10 respective tables in Azure SQL DB. requirement with the introduction of a Domain-specific language (DSL) that acts as an Before our engagement with them, PLC operators would need to manually configure each of the relevant PLCs on the factory When building an automated workflow you need to spend time making your workflow dynamic to be able to scale up quickly and be able to handle large volumes of files without manual work. parameters and the closure activity. deserialize the workflow definition. For now, leave the file path blank and press OK. A guide to using TypeScript Generics as a way to create reusable logic that will work for a multitude of types. Cool! Since were dealing with a Copy Activity where the metadata changes for each run, the mapping is not defined. Notice that the box turns blue, and that a delete icon appears. For multiple inputs, see. If I put @utcnow() (or @{utcnow()}) in the main parameter and set the execute pipeline parameter to that parameter it does not work. Here are my results: I've noticed: In the following example, the BlobDataset takes a parameter named path. considering using DTFx and want to tailor it to your specific needs. A dataset was created for Azure SQL DB with parameters for SchemaName and TableName: The parameters are then used in the Table properties on the Connection settings: 2. Step 2: Create Dataset ParametersIn tab Parameters, you create 3 parameters: Container represents the container in ADLS where the file is located. Enter as name fileName of type String with empty Value. The same pattern can be used to check When promoting a data factory using the continuous integration and deployment process (CI/CD), you can override these parameters in each environment. Azure Data Factory - Use system variable in Dynamic Content. SummaryTo pass parameters between Data Factory and Databricks, we performed the following steps: (1) set Data Factory pipeline variable input_value = 1 (2) set Data Factory Notebook activity Base parameter adf_input_value = input_value (3) pick up adf_input_value in Databricks notebook (4) generate and return adf_output_value from Databricks to Data Factory (5) set Data Factory pipeline variable output_value = adf_output_value. For example, instead of hardcoding the file name from Rebrickable in each dataset, we can parameterize the file name value. Creating hardcoded datasets and pipelines is not a bad thing in itself. (Oof, that was a lot of sets. For example, to convert the pipeline trigger time into a data flow parameter, you can use toTimestamp(left('@{pipeline().TriggerTime}', 23), 'yyyy-MM-dd\'T\'HH:mm:ss.SSS'). Return the string version for a data URI. influence the overall design of the engine, so its highly recommended to identify these needs as early as possible. The only difference to other activities is when They're useful when you have multiple pipelines with identical parameter names and values. Current version/Synapse version APPLIES TO: Azure Data Factory Azure Synapse Analytics This article provides details about expressions and functions supported by Azure Data Factory and Azure Synapse Analytics. Here you can store SAS URIs for blob store. Azure data factory - pass multiple values from lookup into dynamic query? Azure Data Factory The second option is to create a pipeline parameter and pass the parameter value from the pipeline into the dataset. Data Flows can only support up to 3 millisecond digits. Also hardcoding the partition column name and partition ranges does not fit well into a metadata-driven pipeline I may have different partition column names for each table, different data types, different column expressions as well as different partition ranges. This configuration enables you to dynamically pass a Container, Directory and Filename to your datasets so you can use this to move data from one location to another without hardcoding any file specific information. more user-friendly engine by detecting possible errors or misconfigurations and providing feedback to end-users early. Alright, now that weve got the warnings out the way Lets start by looking at parameters . execution could vary depending on runtime parameters. Please feel free to reach out. For maintainability reasons keeping re-usable functions in a separate notebook and running them embedded where required. To make life of our users who are querying the data lake a bit easier, we want to consolidate all those files into one single file. You can read more about this in the following blog post: https://sqlkover.com/dynamically-map-json-to-sql-in-azure-data-factory/, Your email address will not be published. The same pipelines structure is used, but the Copy Activity will now have a different source and sink. You can now carry out any data manipulation or cleaning before outputting the data into a container. The idea here is you can pass a variable or pipeline parameter to these values. In the finally { } block we check throws a ParseException as shown in the previous snippets. Hence, we needed a way to supply a cancellation token down to each activity in the workflow. generated from previous steps of the workflow. task for that activity and schedules it for execution. The parameters are later used in the Lookup Activity and Copy Data Activity. Passing parameters, embedding notebooks, running notebooks on a single job cluster. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. When you read an API endpoint, it stores a file inside a folder with the name of the division. Check whether the first value is greater than the second value. 2. As for DSL base language, we chose JSON over Yaml due to easier writing and better support from C# libraries. We relied also on attributes to specify required JSON properties and implemented and use the token in any other method calls it might make. Take it with a grain of salt, there are other documented ways of connecting with Scala or pyspark and loading the data into a Spark dataframe rather than a pandas dataframe. operators, fields, properties etc. In our specific customer scenario, where the workflow engine runs on a factory edge, workflows need to finish ). Tip: Verify whether a static workflow configuration is sufficient for your business needs or whether workflow Step 1: Simple skeletal data pipeline. After creating the code block for connection and loading the data into a dataframe. The partition column name only allows a column name, not an expression. https://www.linkedin.com/company/azure-tutorials. Return the binary version for an input value. only to a pre-defined set of types: only primitive In this activity we will trigger the Databricks notebook. For the purpose of this blog, we use a very simple scenario where we: 1. This expression will be evaluated as is when referenced. To alter multiple parameters at once, select Edit all. a step is attempting to use data from a previous step that does not exist) is This could happen due to Parameters can be passed into a pipeline in three ways. Below is the Input of the Copy Data activity run output, showing the new column that was added to the source query and the upper bound and lower bound ranges of the data: Since I only had one year of data, you can see that the number of parallel copies used was only 1: Parallelism in Copy Data activities provides the opportunity for data ingestion performance improvements. The structures for your custom DSL will depend on its intended purpose and the business needs. To handle this case, we were asked to give a user an opportunity to specify a timeout value for the entire workflow. And thats it! Then copy all the data from your Azure Data Lake Storage into your Azure SQL Database. Azure Certified IT Engineer with 7+ years of experience in the banking industry. When referenced, pipeline parameters are evaluated and then their value is used in the data flow expression language. Setting dynamic content as Pipeline Parameter's default value? By parameterizing resources, you can reuse them with different values each time. Global parameters are constants across a data factory that can be consumed by a pipeline in any expression. If you pass in an invalid expression or reference a schema column that doesn't exist in that transformation, the parameter will evaluate to null. Fun! floor. operator (as in case of subfield1 and subfield2), @activity('*activityName*').output.*subfield1*.*subfield2*[pipeline().parameters.*subfield3*].*subfield4*. If I put @utcnow() in a set variable activity and set the execute pipeline parameter to that variable it works. Hopefully you may pickup something useful from this, or maybe have some tips for me. @activity({notebookActivityName}).output[runOutput][{toDataFactoryVariableName}]. Its magic . A common task in Azure Data Factory is to combine strings, for example multiple parameters, or some text and a parameter. ensure safety and communicate issues earlier to factory operators. the implementation of the Domain Specific Language (DSL) with workflow validation, dynamic expressions and data flow, You, the user, can define which parameter value to use, for example when you click debug: That opens the pipeline run pane where you can set the parameter value: You can set the parameter value when you trigger now: That opens the pipeline run pane where you can set the parameter value. For efficiency when dealing with jobs smaller in terms of processing work (Not quite big data tasks), dynamically running notebooks on a single job cluster. To reference a pipeline parameter that evaluates to a sub-field, use [] syntax instead of dot(.) We will continue to support it. Later, we will look at variables, loops, and lookups. Change of equilibrium constant with respect to temperature. Click the new FileName parameter: The FileName parameter will be added to the dynamic content. For each parameter, you must assign a name, select a type, and optionally set a default value. include all issues found, to allow for resolution of them at once. A function can be called within an expression.). If expression is not checked (default behavior). the timeout, we tell DTFx to purge the running orchestration, so that it can be cleaned up. Best practices and the latest news on Microsoft FastTrack, The employee experience platform to help people thrive at work, Expand your Azure partner-to-partner network, Bringing IT Pros together through In-Person & Virtual events. The RunTaskInternal() method is a method of our custom WorkflowOrchestrator and is used to execute a workflow. The main idea is to build out a shell pipeline in which we can make any instances of variables parametric. Not to mention, the risk of manual errors goes drastically up when you feel like you create the same resource over and over and over again. In some cases, workflows could take a long time to be completed. If the exception is not caught and She loves data and coding, as well as teaching and sharing knowledge - oh, and sci-fi, coffee, chocolate, and cats , Or subscribe directly on tinyletter.com/cathrine. Based on the result, return a specified value. This can be done by creating a Base parameter for every variable that you want to pass. As its value, select adf_output_value from the Notebook activity result: As you can see, to fetch the output of a notebook activity and assign it to a variable use: Run the pipeline and assess the results of the individual activities. Return the highest value from a set of numbers or an array. Connect and share knowledge within a single location that is structured and easy to search. The Data Factory in my demo environment uses Azure SQL DB as the source. Another requirement was to be able to influence the workflow execution based on input provided externally at workflow Parameters can be referenced in any data flow expression. After creating the connection next step is the component in the workflow. This is a popular use case for parameters. You will find the list of available parameters inside of the Expression Builder under the Parameters tab. Click that to create a new parameter. Dynamic content editor converts above content to expression "{ \n \"type\": \"@{if(equals(1, 2), 'Blob', 'Table' )}\",\n \"name\": \"@{toUpper('myData')}\"\n}". If you've already registered, sign in. Or 100 tables from a source database? "Answer is: @{pipeline().parameters.myNumber}", "@concat('Answer is: ', string(pipeline().parameters.myNumber))", "Answer is: @@{pipeline().parameters.myNumber}". If the column is defined in the data flow schema, you can reference it directly as a string expression. System.Linq.Dynamic.Core.DynamicClass. In the Source pane, we enter the following configuration: Most parameters are optional, but since ADF doesnt understand the concept of an optional parameter and doesnt allow to directly enter an empty string, we need to use a little work around by using an expression: @toLower(). (being the objective to transform a JSON file with unstructured data into a SQL table for reporting purposes. Other than that, whats not to like about this? Would it be possible to build a powerless holographic projector? In our case, syntactic validation (e.g. official documentation for Azure Durable Functions. Elegant way to write a system of ODEs with a Matrix. These functions are used to convert between each of the native types in the language: These functions can be used for either types of numbers: integers and floats. The implementation makes use of a Durable Timer implemented using try/finally syntax in C#. To achieve this, set the Data Factory variable type of the relevant variable to Array. Using string interpolation, the result is always a string. storing execution input values as well as generated values at runtime. using the DynamicLinqType attribute on a custom type. Both of these were stored as properties in an instance of If you start spending more time figuring out how to make your solution work for all sources and all edge-cases, or if you start getting lost in your own framework stop. Go to Datasets > New Dataset > Azure Data Lake Storage Gen 2 > Binary. In this version of Analytics the focus has been on changing the Azure data factory deployment process and adding new fact tables and reports for Tenders from POS and POS transactions that are not sales. It Find centralized, trusted content and collaborate around the technologies you use most. You will receive an errorcode "{"code":"BadRequest","message":"ErrorCode=InvalidTemplate,ErrorMessage=The expression >'pipeline().globalParameters.myparam-dbtest-url' is not valid: ..}". Otherwise, register and sign in. I definitely feel like I've done this successfully before. Last step of this is sanitizing the active processing container and shipping the new file into a blob container of its own or with other collated data. Reducing as many hard coded values will cut the amount of changes needed when utilizing the shell pipeline for related other work. To Then, that parameter can be passed into the pipeline and used in an activity. The source and sink directories are parameterized, where the values for these variables are populated during runtime. official documentation for Azure Durable Functions, Guidelines for Organizing and Testing Your Terraform Configuration, Login to edit/delete your existing comments, parsing, evaluating as well as validating dynamic expressions. Click on the Value text box > Add dynamic content, and select input_value from the pane that appears. Check your spam filter). The following sections provide information about the functions that can be used in an expression. we found that workflow engines would be good candidates to base our solution upon. To create a global parameter, go to the Global parameters tab in the Manage section. This makes it particularly useful because they can be scheduled to be passed using a trigger. The workflows we are dealing with have (write) access to machines on the factory floor, so validation of dynamic Azure Tutorials frequently publishes tutorials, best practices, insights or updates about Azure Services, to contribute to the Azure Community. In our example, we name it adf_input_value. The result of this expression is a JSON format string showed below. runtime construct, containing all details needed to execute the workflow. The json is an array of objects, but each object has a few properties that are arrays themselves. this, we implemented a class that maps a DTFx orchestration context to a CancellationTokenSource and stores this map Expressions can appear anywhere in a JSON string value and always result in another JSON value. This could happen due to various reasons, Generate a constant value in a Data Factory pipeline variable named input_value;2. pass input_value to a Databricks notebook, execute some simple logic, and return a result variable to Data Factory;3. pick up the result from the notebook in Data Factory, and store it in a Data Factory pipeline variable named output_value for further processing. Return the string version for an input value. The parameter values are set by the calling pipeline via the Execute Data Flow activity. In our scenario, we want to pass pipeline variable input_value to the notebook. The pipeline first performs a Lookup to return the upper bound and lower bound partition values for the column expression. floor to obtain desired output/results. cancellations. For example, 'string part 1' + $variable + 'string part 2', More info about Internet Explorer and Microsoft Edge, Use the pipeline control flow expression language to set a dynamic value, Use the data flow expression language to set a dynamic value, Use either expression language to set a static literal value. For example, if the notebook will return an Array to Data Factory, then make sure the Data Factory pipeline variable that will pick up the notebook result is of type Array. Notebook. types and types from the System.Math and System.Convert namespaces are accessible. Two datasets, one pipeline. characteristics, broad capabilities, big community and Microsoft support. More info about Internet Explorer and Microsoft Edge, continuous integration and deployment process. Return the day of the month component from a timestamp.
