Questions J Oliver EventStore V2.0

I am starting a project using CQRS and intend to use J Oliver EventStore V2.0 as an event persistence mechanism.

1) In the documentation, ExampleUsage.cs uses 3 serializers in the "BuildSerializer". I suppose this is just to show the flexibility of the deserialization process?

2) In the case of "Restart after failure", when some events were not sent, I believe that I need a start code that calls GetUndispatchedCommits () and then sends them, right?

3) Again, in “ExampleUseage.cs” it would be useful if “TakeSnapshot” added a third event to the eventstore and then “LoadFromSnapShotForward” not only retrieved the most recent snapshot, but also retrieved the events that were after the snapshot to simulate unit recovery.

4) I do not see the use of saving old pictures. Can you give an example of use where they would be useful?

5) If I have a service that handles receiving commands and generating events, then what proposed strategy tracks the number of events since the last snapshot for this unit. Of course, I don’t want to refer too often to "GetStreamsToSnapshot".

6) In the SqlPersistence.SqlDialects namespace, the sql operator name is "GetStreamsRequiringSnaphots" and not "GetStreamsRequiringSnapShots"

1) There are several “basic” serializers, such as the Binary, JSON, and BSON serializers. The other two in the example - GZip / compression and encryption serializers - are batch serializers and are intended only to modify what has already been serialized into a byte stream. For example, I am just demonstrating flexibility. You do not need to encrypt if you do not want to. Actually, I have a job in which simple JSON works, which makes debugging very simple, because all this is text.
