[jira] [Updated] (BEAM-10068) Modify behavior of Dynamic
Destinations
[ https://issues.apache.org/jira/browse/BEAM-10068?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mihir Borkar updated BEAM-10068:
--------------------------------
Description:
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.
