-----------------------------------
Summary: Reuse FileFormat instead of DecodingFormat/EncodingFormat
to ensure thread safety.
Key: FLINK-27070
URL: https://issues.apache.org/jira/browse/FLINK-27070
Project: Flink
Issue Type: Sub-task
Components: Table Store
Affects Versions: 0.1.0
Reporter: Caizhi Weng
Fix For: 0.1.0
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.
