They were failing because the maximum App Engine task batch size is 1,000, and we currently have more than 4,000 tasks in the pull queue. We keep re-uploading those to NORDN because we're unable to delete the tasks after successful upload, so the leases expire and they get processed again. Also renames TaskEnqueuer to TaskQueueUtils to reflect its newly expanded role. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=197060903

/**

|
* 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.
