I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help 
the community manage its development. I see this issues has been marked as 
Major but is unassigned and neither itself nor its Sub-Tasks have been updated 
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this 
ticket is a Major, please either assign yourself or give an update. Afterwards, 
please remove the label or in 7 days the issue will be deprioritized.

> I think we should consider to always set a default environment when we create 
> the DBOptions.
> See https://github.com/facebook/rocksdb/wiki/rocksdb-basics:
> *Support for Multiple Embedded Databases in the same process*
> A common use-case for RocksDB is that applications inherently partition their 
> data set into logical partitions or shards. This technique benefits 
> application load balancing and fast recovery from faults. This means that a 
> single server process should be able to operate multiple RocksDB databases 
> simultaneously. This is done via an environment object named Env. Among other 
> things, a thread pool is associated with an Env. If applications want to 
> share a common thread pool (for background compactions) among multiple 
> database instances, then it should use the same Env object for opening those 
> databases.
> Similarly, multiple database instances may share the same block cache.
