SUMMARY

If a user somehow creates a table with a null name, 503 errors occur whenever repr(table) is called because __repr__ returns a non-string type.

Fixed schema to make columns referenced by __repr__ non-nullable.

Before running the migration, you must manually fix any records with null clusters.cluster_name, dbs.database_name, or tables.table_name. To find problematic records, run a query like:

SELECT 
    *
FROM 
   tables
WHERE 
   table_name IS NULL

TEST PLAN

Confirmed that after upgrade, I get a warning if I try to insert a row with a null table_name.

Confirmed that after downgrade, I am able to insert a row with a null table_name with no problem.

ADDITIONAL INFORMATION

  • Has associated issue:
  • Changes UI
  • Requires DB Migration.
  • Confirm DB Migration upgrade and downgrade tested.
  • Introduces new feature or API
  • Removes existing feature or API

@serenajiang would you mind adding the Alembic migration to the PR?

Please remove this as the migration should fail if there are NULL values. Instead please add a line item to UPDATING.md to indicate that this migration may fail (see other examples).
