Ilya Shishkov updated IGNITE-25641:
-----------------------------------
Description:
{{CacheInterceptor#onBeforePut}} can be invoked twice, and second call occurs
after committing to external database in {{CacheStoreSession#onSessionEnd}}. In
case of failure in interceptor during second invocation we will get
inconsistency between external database and Ignite cache.
As you can see in attached reproducer
([^CacheStoreWithInterceptorFailureTest.patch]), second invocation happens on
origination node, i.e. on transaction coordinator.
If transaction coordinator is primary, then fail in second invocation on
primary leads to inconsistency between cache and external storage.
