> When testing table store I'm faced with the following warning messages:
> {code}
> 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]
> {code}
> 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.
