[GitHub] [flink-table-store] tsreaper opened a new pull request, #74: [FLINK-27070] Reuse FileFormat instead of DecodingFormat/EncodingFormat to ensure thread safety

tsreaper opened a new pull request, #74:
URL: https://github.com/apache/flink-table-store/pull/74

   When testing table store I'm faced with the following warning messages:
   
   ```
   org.apache.org.impl.MemoryManagerImpl [] - Owner thread expected Thread[Writer -> Local Committer (1/16)#0,5,Flink Task Threads], got Thread[pool-8-thread-1,5,Flink Task Threads]
   ```
   
   This is because `OrcBulkWriterFactory` is not thread safe (it keeps `WriterOptions` as a class member and creates writers from the same `WriterOptions` object, which is not thread safe).
   
   What we should do is to reuse `FileFormat` instead of `DecodingFormat`/`EncodingFormat` to ensure thread safety.
