Geoffrey Jacoby updated PHOENIX-5435:
-------------------------------------
Issue Type: Sub-task (was: New Feature)
Parent: PHOENIX-5442
> Annotate HBase WALs with Phoenix Metadata
> -----------------------------------------
>
> Key: PHOENIX-5435
> URL: https://issues.apache.org/jira/browse/PHOENIX-5435
> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Geoffrey Jacoby
> Assignee: Geoffrey Jacoby
> Priority: Major
>
> HBase write-ahead-logs (WALs) drive not only failure recovery, but HBase
> replication and some HBase backup frameworks. The WALs contain HBase-level
> metadata such as table and region, but lack Phoenix-level metadata. That
> means that it's quite difficult to build correct logic that needs to know
> about Phoenix-level constructs such as multi-tenancy, views, or indexes.
> HBASE-22622 and HBASE-22623 add the capacity for coprocessors to annotate
> extra key/value pairs of metadata into the HBase WAL. We should have the
> option to annotate the tuple <tenant_id, table-or-view-name, timestamp>, or
> some hashed way to reconstruct that tuple into the WAL. It should have a
> feature toggle so operators who don't need it don't bear the slight extra
> storage cost.
