RocksDB default logging configuration

[Bajaj, Abhinav]

Hi,

Some of our teams ran into the disk space issues because of RocksDB default 
logging configuration - 
FLINK-15068<https://issues.apache.org/jira/browse/FLINK-15068>.
It seems the workaround suggested uses the OptionsFactory to set some of the 
parameters from inside the job.

Since we provision the Flink cluster(version 1.7.1) for the teams, we control 
the RocksDB statebackend configuration from flink-conf.yaml.
And it seems there isn’t any related RocksDB 
configuration<https://ci.apache.org/projects/flink/flink-docs-release-1.7/ops/config.html#rocksdb-state-backend>
 to set in flink-conf.yaml.

Is there a way for the job developer to retrieve the default statebackend 
information from the cluster in the job and set the DBOptions on top of it?

Appreciate the help!

PS:  Sharing below snippet as desired option if possible -

StreamExecutionEnvironment streamExecEnv = 
StreamExecutionEnvironment.getExecutionEnvironment();
StateBackend stateBackend = streamExecEnv.getDefaultStateBackend();
stateBackend.setOptions(new OptionsFactory() {
@Override
public DBOptions createDBOptions(DBOptions dbOptions) {
  dbOptions.setInfoLogLevel(InfoLogLevel.WARN_LEVEL);
  dbOptions.setMaxLogFileSize(1024 * 1024)
  return dbOptions;
}

@Override
public ColumnFamilyOptions createColumnOptions(ColumnFamilyOptions 
columnFamilyOptions) {
  return columnFamilyOptions;
}
});
