Wait for database update to become durable#4846
Merged
Conversation
Confirmed reads applies only to subscription clients, calls to the the HTTP API publish endpoint return a success response before the operation is confirmed. While we await scheduling of a new database, updates require to wait for the update transaction to be confirmed. To allow this, the `TransactionOffset` channel and the database's `DurableOffset` need to be returned all the way up to the request handler. Note that waiting for confirmation is almost always the right choice, so can't be opted out of at the time of submission of this patch. Callers may, however, extend the timeout after which waiting for confirmation is cancelled.

Oh, something I forgot to include in my review: I agree that this is a reasonable behavior, and I don't see the need to make it more configurable than this. |
