[basex-talk] Locking and long-running update operations

I have a set of expensive cached data which requires about ~20 minutes to refresh/recalculate. However -- while this recalculation is running (via a single XQUF operation), read queries against the same database are unable to operate.

My expectation is that the old, pre-update data will remain continually available until the update commits. If this expectation is incorrect, what is the suggested mechanism for running such expensive updates without impacting availability?
