[jira] [Created] (IGNITE-11801) Clearing of moving partition may
lead to partition desync.
Alexei Scherbakov created IGNITE-11801:
------------------------------------------
Summary: Clearing of moving partition may lead to partition desync.
Key: IGNITE-11801
URL: https://issues.apache.org/jira/browse/IGNITE-11801
Project: Ignite
Issue Type: Bug
Reporter: Alexei Scherbakov
{{o.a.i.i.processors.cache.distributed.dht.topology.GridDhtLocalPartition#tryClear}}
calls {{org.apache.ignite.internal.processors.cache.distributed.dht.topology.GridDhtLocalPartition#clearAll}}
Inside clearAll {{clearVer = ctx.versions().next();}} is defined on call time, but this may happen after exchange future is finished and some update already applied to MOVING partition resulting in removal of actual data from partition.
Fix: assign clear version before exchange future is finished.
