Why I'm doing:

We will return publish success after tablet apply finished if we enable sync publish to avoid waiting apply during query. However, if BE restart, we will return publish success even though the apply is not finished. So the query may get query time out issue after BE restarted.

The reason is the transaction related tablets is lost after BE restart. For primary key table, if BE receive publish request, BE will delete committed rowset meta and rewrite rowset meta into TabletMeta, so the transaction related tablet info are lost if we restart BE during waiting apply finished.

What I'm doing:

If BE restarted, add the tablet which max_readable_version less than request_version into error_tablet_ids. Then the transaction will be visible until all those tablets apply finished.
