> A unique writeId has to be assigned for the table in global locks because
> this will help in cleanup of records in COMPLETED_TXN_COMPONENTS table.
> Currently the writeId is NULL for this table. There was a situation which
> lead to large number of records in COMPLETED_TXN_COMPONENTS table because
> these records had writeId as NULL and this subsequently lead to OOM errors.
