> Support index metadata backup and restore
> -----------------------------------------
>
> Key: TAJO-1302
> URL: https://issues.apache.org/jira/browse/TAJO-1302
> Project: Tajo
> Issue Type: Sub-task
> Components: Catalog, Index
> Reporter: Jihoon Son
> Assignee: Jihoon Son
> Priority: Minor
> Fix For: index support
>
>
> Currently, users cannot backup (and thus restore) the index metadata stored
> in the catalog. As a result, if the catalog database is broken, they should
> recreate the pre-exiting indexes, which may take a long time.
> Thus, we should support the backup and restore of index metadata.
