Right now ZCatalog randomly generates ConflictErrors even if there are no conflicts in the data being indexed. It's quite rare, however, and there's machinery that retries the entire transaction up to three times when it happens.
If the current mechanism is reliable, and efficient (given that conflict/retries are rare) then I dont understand the motivation....
The system becomes less reliable as server load increases. Large catalog updates (where every object is reindexed) also generate a lot of conflicts.
But I want it to be more reliable, especially so that ZCatalog can be used in ZODB applications outside Zope.
Is it because other non-Zope applications might not be so proficient at performing retries?
Yes. Long-running transactions are especially problematic. Shane
