Snapshotting

• EventStoreDB doesn't support snapshotting.

How to implement snapshotting

1. Events are appended to the stream post-123
2. Every nth event, a snapshot is appended to the stream e.g. post_snapshot-123
   • use _ instead of - in the suffix _snapshot, - is used by the system projection
3. Read backwards a single result from post_snapshot-123 stream

   ReadStreamOptions options = ReadStreamOptions.get()
       .backwards()
       .fromEnd();
   
   ReadResult result = client.readStream("order_snapshot-123", 1 /*maxCount*/, options)
       .get();
   
   List<ResolvedEvent> events = result.getEvents();

4. Read forwards from nth revisino from post-123 stream

   ReadStreamOptions options = ReadStreamOptions.get()
       .forwards()
       .fromRevision(n);
   
   ReadResult result = client.readStream("order-123", options)
       .get();
   
   List<ResolvedEvent> events = result.getEvents();
