>                 Key: HDDS-14031
>                 URL: https://issues.apache.org/jira/browse/HDDS-14031
>             Project: Apache Ozone
>          Issue Type: Improvement
>            Reporter: Swaminathan Balachandran
>            Assignee: Swaminathan Balachandran
>            Priority: Major
>
> Currently the OmSnapshotManager handles snapshot db by directly using 
> ManagedRocksdb layer instead of the DBStore layer already written under 
> hdds-server-framework. This is redundant code and also unoptimal since the 
> implementation allocates new byte arrays for each and every write and read 
> to/from the db instead of CodecBuffers which can have memory issues.
