[GitHub] [beam] damccorm opened a new issue, #21017: Allow managed thread count in AvroIO

damccorm opened a new issue, #21017:
URL: https://github.com/apache/beam/issues/21017

   During execution, the `ReadAllViaFileBasedSource` runs ReShuffle and creates an un-grouped set of file range readers.  This can easily cause OOM issues when the number of groups changes as there is no limit to the number of concurrent file reads.
   
    
   
   Using Reshuffle.viaRandomKeys.withNumBuckets instead will allow the same default behavior, but lets the user configure the number of readers as and when needed.
   
   Imported from Jira [BEAM-12685](https://issues.apache.org/jira/browse/BEAM-12685). Original Jira may contain additional context.
