class CreatePseudonymAuditorsCassandra < ActiveRecord::Migration[6.1]
# Instructure won't be using any cassandra tables
# for auditor changes to feature flags,
# but some open source users may still be within the deprecation
# window, so we'll include these tables so they can keep using
# cassandra as a write target if they want until that gets remove.
# TODO: When cassandra auditors are fully removed,
# this migration can be deleted entirely.
