[jira] [Created] (IGNITE-22299) CDC resend doesn't affect conflicted entries
Maksim Timonin created IGNITE-22299:
---------------------------------------
Summary: CDC resend doesn't affect conflicted entries
Key: IGNITE-22299
URL: https://issues.apache.org/jira/browse/IGNITE-22299
Project: Ignite
Issue Type: Bug
Reporter: Maksim Timonin
Assignee: Maksim Timonin
CDC resend is util to resend whole cache data from one cluster to another. It logs cache entries to WAL and then the ignite-cdc process them.
But the ignite-cdc process has protection against looping entries. Replicated entries has special mark - GridCacheVersionEx#drMap. By this flag ignite-cdc filteres records and doesn't send them to receiver.
Then records replicated from other cluster are failed to be resend.
Steps to reproduce:
# put(0, 1)
# putAllConflict(0, 2)
# start cdc resend
# the record isn't sent
