> To enable the faster incremental rebuild of materialized views presence of
> update/delete operations on the source tables of the view since the last
> rebuild must be checked. Based on the outcome different plan is generated for
> scenarios in presence of update/delete and insert only operations.
> Currently this is done by querying the COMPLETED_TXN_COMPONENTS table however
> the records from this table is cleaned when MV source tables are compacted.
> This reduces the chances of incremental MV rebuild.
> The goal of this patch is to find an alternative way to store and retrieve
> this information.
