Are there any places in code you have observed that batch is not called within try enclosed resource?
Because in OM we use this, and we have used as   
{code:java}
try(BatchOperation batchOperation = omMetadataManager.getStore()
              .initBatchOperation())
{code}

> there are a number of places in the code where BatchOperation is used but not closed. As a best practice, better to close them explicitly.
> I have a stress test code that uses BatchOperation to insert into OM rocksdb. Without closing BatchOperation explicitly, the process crashes after just a few minutes.
