Alternative for the current sleep of one second before setting the workflow lock. It partially reverts a change by @qqmyers from 2018 in which a call to
em.find
was replaced byem.merge
(which is explained by a comment in the function). This turns out to lead to a lot ofOptimisticLockException
s inlockDataset
, probably because the increased amount of time between the fetching ofDataset
and its persistence inlockDataset
.Reverting this change for the
lockDataset
-scenario decreased the number of failures because ofOptimisticLockException
from around 170 out of 700 imports to 0. The sleep of 1 second seems to work, too, but has the disadvantage of increased overall import time (ca 27 hours for 100,000 dataset, so significant).
