What's the alternative to get_engine(bind="replica") in versions 3+?

[andrii-korotkov-verkada]

Hey. The database is set up to have write and read replicas. There are some methods used on read replica engine, such as get_engine(bind="replica").pool.overflow on SQLAlchemy object. But get_engine is deprecated in v3. What's the alternative way to achieve the same goal?

The deprecation warning shows the following message:

'get_engine' is deprecated and will be removed in Flask-SQLAlchemy 3.2. Use 'engine' or 'engines[key]' instead. If you're using Flask-Migrate or Alembic, you'll need to update your 'env.py' file.

Therefore: db.engines["replica"]
