[GitHub] [beam] Abacn opened a new issue, #25211: [Task]: Basic bundle strategy for direct runner

["Abacn (via GitHub)" <gi...@apache.org>]

Abacn opened a new issue, #25211:
URL: https://github.com/apache/beam/issues/25211

   ### What needs to happen?
   
   Elements incoming for Java direct runner are not bundled, i.e., all in bundle size = 1. Some flakiness in our unit test is likely due to this issue. For example, it is found that BigQueryWriterTest is flaky due to intermittent time out (context #25207) the issue is traced down to fact that some batch load and file load tests concurrently write thousand of files locally.
   
   e.g. https://ci-beam.apache.org/job/beam_PreCommit_Java_GCP_IO_Direct_Phrase/57/testReport/junit/org.apache.beam.sdk.io.gcp.bigquery/BigQueryIOWriteTest/testWriteDynamicDestinationsBatchWithSchemas_0_/
   
   the complete log will show (tested locally) 2,000 lines of org.apache.beam.sdk.io.gcp.bigquery.BigQueryRowWriter <init> log. Since the largest concurrent file open is limited, test sometimes get stuck

   Well, actually the bundle size being 1 for `testWriteDynamicDestinationsBatchWithSchemas_0_/` is mostly due to the test setting `.withMaxFileSize(10)` which makes each row having a file. Leaving this open for further improvement (though low priority)
