[CONTROLLER-963] Clustering : Use Normalized Node streaming code when persisting snapshots and replicating snapshots

Blocks — Tue, 25 Jul 2023 08:24:14 +0000

Use NormalizedNode stream writer when,
1. Persisting a snapshot

The transaction that reads the data from the store should not serialize the NormalizedNode
CaptureSnapshotReply should pass the read NormalizedNode to the RaftActor wrapped by a Serializable. This will keep the interface generic.
To reduce memory issue the captured snapshot will not be stored in memory

2. Install snapshot

Change message to java serializable and rely on akka to write the serializable to the stream
When a snapshot needs to be installed the snapshot needs to be created.
