Create Snapshot with CommandInterpreter pattern?

[datasatanic]

In docs not enough information about Snapshot. How I understand snapshot is simple command (implementing serialization/desirialization in CommandFormatter etc). How concatinate WriteToAsync in inherit from SnapshotBuilder and Command?

Hi @datasatanic , you need to use CommandHandlerAttribute with IsSnapshotHandler as mentioned in the documentation. This allows to capture snapshot entry when replaying log at application startup. SnapshotBuilder is ephemeral log entry so you need it only for implementing snapshot construction logic. Inside of snapshot builder you can construct a command representing the snapshot and call your formatter from WriteToAsync implementation.
