> CDC DDL to support maxLookback for CDC index
> --------------------------------------------
>
> Key: PHOENIX-7671
> URL: https://issues.apache.org/jira/browse/PHOENIX-7671
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
>
> TTL of the CDC index is same as the maxLookback configured at the cluster
> level. If the data table has different value of maxLookback than cluster
> level, the table level maxLookback is not used as TTL by the cdc index of the
> same data table. Any table property sync from the data table to index table
> can only be efficiently done if the table property is stored in
> SYSTEM.CATALOG.
> The maxLookback is not stored in SYSTEM.CATALOG, however it can be stored in
> HBase TableDescriptor.
> The purpose of this Jira is to provide CDC DDL statement with maxLookback
> value that should be used as CDC index maxLookback (and therefore it's TTL)
> value, regardless of the maxLookback value configured at the cluster level.
> This allows various CDC indexes to have their own TTL values.
