Subject [jira] [Assigned] (PHOENIX-2948) Snapshot support for Phoenix Tables
Date Tue, 04 Oct 2016 05:54:20 GMT


Sergey Soldatov reassigned PHOENIX-2948:

    Assignee: Sergey Soldatov

> Snapshot support for Phoenix Tables
> -----------------------------------
>                 Key: PHOENIX-2948
>                 URL:
>             Project: Phoenix
>          Issue Type: New Feature
>    Affects Versions: 4.7.0
>            Reporter: Anil Gupta
>            Assignee: Sergey Soldatov
>              Labels: Backup/Restore
> 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.
