Anil Gupta updated PHOENIX-2948:
--------------------------------
Description:
As discussed in PhoenixCon, here is the description of desired Snapshot feature
in Phoenix:
Currently, Phoenix does not supports taking snapshots of Table.
HBase has support for taking snapshot of table so Phoenix should also support
taking snapshot for taking backups of data.
At present, taking backup of a Phoenix is highly manual and detail oriented
process and in some cases its not even possible to take a snapshot because
Metadata of all Phoenix tables is stored in one system table. We cant take
snapshot of entire system table for making a backup/restore of one particular
table.
These are scenarios that we should handle in Phoenix Snapshot:
1. Handling Global and Local secondary index.
2. Snapshotting Table schema.
3. Handling views. I am not sure how. But just highlighting it.
I think #2 above requires most of the work. IMO, #1 should be easy to handle.
