[jira] [Commented] (HDDS-6852) Snapshot Aware OMMetadataManager

["George Jahad (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDDS-6852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17563398#comment-17563398 ] 

George Jahad commented on HDDS-6852:
------------------------------------

Based on my POC's and discussions with Nanda, it seems better to approach this as follows:

Instead of modifying the metadataManager to all a single instance to support both the active fs tables and the snapshot tables, it seems cleaner to create separate metadataManager instances for each snapshot, and use that instance to creat a keymanager instance for the snapshots.

(Since we will not use the volume or bucket info from the snapshot, we should be able to use the standard volume/bucket manager instances.)

> We need to add methods in OMMetadataManager to make it snapshot aware.
> Specifically, all the methods OMMetadataManager::get*Table() by default return rocksDB table associated with the active ObjectStore by default. We need to add methods to get the tables corresponding to the given Snapshot.
