> Modify behavior of Dynamic Destinations
> ---------------------------------------
>
> Key: BEAM-10068
> URL: https://issues.apache.org/jira/browse/BEAM-10068
> Project: Beam
> Issue Type: New Feature
> Components: sdk-java-core
> Reporter: Mihir Borkar
> Priority: P2
> Labels: stale-P2
>
> The writeDynamic() method, implementing Dynamic Destinations writes files per
> destination per window per pane.
> This leads to an increase in the number of files generated.
> The request is as follows:
> A way to make it possible for the user to modify the behavior of Dynamic
> Destinations to control the number of output files being produced.
> a.) We can consider adding user-configurable parameters like writers per
> bundle, increasing number of records processed per bundle
> and/or
> b.) Introduce a method implementing Dynamic Destinations but more dependent
> on the data passing through the pipeline, instead of windows/panes.
> So instead of splitting every output file into roughly the number of
> destinations being written to, we let the user configure how output files
> should be divided across destinations.
