This is a 'green' Flogger migration CL. Green CLs are intended to be as safe as possible and should be easy to review and submit. No changes should be necessary to the code itself prior to submission, but small changes to BUILD files may be required. Changes within files are completely independent of each other, so this CL can be safely split up for review using tools such as Rosie. For more information, see [] Base CL: 197826149 ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=198560170

/**
|
|
* Action that saves commit log checkpoints to Datastore and kicks off a diff export task.
|
|
*
|
|
* <p>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.
|
|
*
|
|
* <p>This action's supported method is GET rather than POST because it gets invoked via cron.
