Stale Data Comes Up on Node restart temporarily

How Developers Are Using Aerospike How Aerospike Works

Scenario:

  1. In a 3 node cluster with replication factor 2, a node was stopped.
  2. Some updates were pushed to all the keys in a given set
  3. Down node was started again with cold start empty false.
  4. When down node was up, i connected to aerospike via aql and checked the keys of that set, and saw stale data for 1/3rd of keys.
  5. After some time when I queried, the data was fine which means eventually it was showing consistent data

Is this behaviour as expected? Can the cluster serve stale data for some period of time when a node is restarted? How is this thing handled?
