Flow Snap Pack

Use Snaps in this Snap Pack to:

  • Route binary documents to different output views based on a boolean expression.
  • Copy a document stream to the Snap's output views.
  • Validate incoming data against a set of defined constraints.
  • Force a pipeline to stop with a failed status if it receives more records than the user-defined threshold.
  • Filter a document stream based on an expression.
  • Invoke a new pipeline for each incoming document.
  • Send the specified number of input documents to the output view relative to the start of the input stream.
  • Route documents to output views based on the incoming HTTP request method.
  • Execute pipelines and flow documents into and out of executions.
  • Route documents to output views matching a boolean expression.
  • Read the specified number of documents from the end of the input stream.
  • Merge document streams into a single output stream.

4.20snapsmrc535-Latest
  • Adds a new Snap, Gate, which enables you to consolidate multiple input streams into a single output document where each input stream is displayed as a label containing the list of records that were received by that input view.
  • The Pipeline Execute Snap now provides the following capabilities:
    • Specify the Snaplex on which to run child Pipelines. You can now select the Snaplex on which to run the child Pipelines through the Execute On and Snaplex Path fields. The default option is executing the child Pipeline on the same Snaplex node as the Parent, but you can also specify a different Snaplex through the drop-down list, which includes the option to manually enter a Snaplex name.
    • Configure retry logic for child Pipeline executions. You can now configure retry logic for child Pipeline executions though the following fields: Number of Retries, Retry Interval, and Timeout fields.
