What changed?
Move the logic for the migration mode to use dynamic config instead of static config. Next step is to clean up the static config once the behavior is tested with multiple configuration changes.
Why?
migration should be done incrementally and this is easier to control with config rollout and not code rollout.
How did you test it?
unit tests and local development.
Potential risks
shard-distributor-canary service cannot operate correctly if shard-distributor do not use the right configuration
