aerospike_migrations – Check or wait for migrations between nodes¶
New in version 2.8.
- This can be used to check for migrations in a cluster. This makes it easy to do a rolling upgrade/update on Aerospike nodes.
- If waiting for migrations is not desired, simply just poll until port 3000 if available or asinfo -v status returns ok
