Subject [jira] [Commented] (HBASE-8642) [Snapshot] List and delete snapshot by table
Date Sat, 01 Jun 2013 01:13:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13671944#comment-13671944

Matteo Bertozzi commented on HBASE-8642:
----------------------------------------

{quote}Table rename is via cloning snapshot currently (so we rename the table this way, pairwisely
we update all mapped snapshots?)?{quote}
No we don't update the other snapshots info... so they have the old table name...

{quote}How about the claiming is that listing/deleting snapshot by table name is based on
current table name available?{quote}
I don't really understand this one... at the moment if you list by table name, you get also
the snapshots of the renamed table.

{quote}Yeah, RDBMS has object (database, tablespace, table, column, etc.) id in catalog, which
make external name changable and transparent to system. Is it possible to using id (shorter)
instead of original name bytes in ROOT/META? Just a question, this involve lots of changes
to current HBase.{quote}
Take a look at the last slide of HBASE-7806 pdf
