### ⚠️ Possible DB migration conflict @MallikarjunaReddyN the base branch `master` picked up a new database migration under `superset/migrations/` after this PR was opened, and this PR adds or modifies migration files too. Alembic migrations form a single linear chain, so if both branch off the same parent revision, merging this PR as-is could leave the migration history with two heads instead of one, which makes `superset db upgrade` fail with `Multiple head revisions are present`. To check and, if needed, fix this: 1. Rebase this branch onto the latest `master`. 2. Run `superset db heads`. If it lists more than one revision, you have a conflict. 3. In your new migration's script, update `down_revision` (and the `Revises` comment) to point at the other head instead, so the chain has a single head again. See [Merging DB Migrations](https://superset.apache.org/docs/contributing/development#merging-db-migrations) in the contributing guide for a worked example. -- This is an automated message from the Apache Git Service.
