> 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.
