One thing that comes to mind is to check what schema version you’re using. You can do this on postgres by running the following:

select * from alembic_version;

If you haven’t run

dagster instance migrate

in a while, that could help a good deal, as we’ve made a bunch of query optimizations (adding db indexes, etc).

The other thing I would look at is to check the capacity of the DB you’re using. If you’re running out of space, you may need to do some cleanup, like deleting old runs, to reclaim some space
