feat: read replica support via connects_to role switching#44
Merged
Conversation
When connects_to is set to { reading: <role>, writing: <role> }, the engine
automatically routes GET requests to the reading role and mutating requests
to the writing role via ActiveRecord::Base.connected_to(role:). Any other
hash (e.g. { role: :writing }) falls through to connected_to directly.
