Semen Boikov commented on IGNITE-5290:
--------------------------------------
Currently I'm doing changes in CQ code and faced the same issue. This caused by
the fact that in GridCacheMapEntry.innerUpdate collection of CQ listeners to
notify if initialized before partition update counter is incremented. Looks
like to avoid this error it should work in this way:
- first get snapshot of listeners (in the same place it is obtained now)
- execute update logic
- before notifying listeners, again get snapshot of listeners, if it changed
then for all added listeners mark current counter as filtered
> Events might be missed during concurrent CQ registration and cache operations
