# Description of Changes Based on,and to fix mentioned issues on #3215 i.e - 1. Mark table for truncation after anaylyzing `TxData::inserts` too. 2. `visit_truncates` can not call `schema_for_tables` for dropped tables as schema info has been deleted from `st_*` tables. Hence, added a field in `ReplayVisitor` to cache table names. This PR decouples truncation info from delete entries, since deletion alone can’t reliably tell about truncation without extra mutations later. Can be reviewed commit wise. # Testing Testing using "Add columns" PR.
