 $collectionReplica$ contains a in-memory local copy of persistent collections. In common cases, the system has multiple query nodes. Data of a collection will be distributed across all the available query nodes, and each query node's $collectionReplica$ will maintain its own share (only part of the collection).
 Every replica tracks a value called tSafe which is the maximum timestamp that the replica is up-to-date.
