CommitLogCheckpointAction

java.lang.Object
- google.registry.backup.CommitLogCheckpointAction

All Implemented Interfaces:

java.lang.Runnable
```
public final class CommitLogCheckpointAction
extends java.lang.Object
implements java.lang.Runnable
```
Action that saves commit log checkpoints to Datastore and kicks off a diff export task.
We separate computing and saving the checkpoint from exporting it because the export to GCS is retryable but should not require the computation of a new checkpoint. Saving the checkpoint and enqueuing the export task are done transactionally, so any checkpoint that is saved will be exported to GCS very soon.
This action's supported method is GET rather than POST because it gets invoked via cron.
