[jira] [Commented] (IGNITE-10740) Add documentation for
IGNITE_DISABLE_TRIGGERING_CACHE_INTERCEPTOR_ON_CONFLICT
[ https://issues.apache.org/jira/browse/IGNITE-10740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16746236#comment-16746236 ]

-----------------------------------------
[~antonovsergey93]
I'm not sure I understand what this option does from the end user standpoint. Why would one want to configure interceptors and then disable them using this option?
What does DR stand for in this context?

> We should add to documentation IGNITE_DISABLE_TRIGGERING_CACHE_INTERCEPTOR_ON_CONFLICT option.
> As a reference you could get javadoc from skipInterceptor() :
> {{Checks, that cache interceptor should be skipped. It is expects by default behavior that Interceptor methods (\{@link CacheInterceptor#onBeforePut(Cache.Entry, Object)}, \{@link CacheInterceptor#onAfterPut(Cache.Entry)}, \{@link CacheInterceptor#onBeforeRemove(Cache.Entry)} and \{@link CacheInterceptor#onAfterRemove(Cache.Entry)}) will be called, but \{@link CacheInterceptor#onGet(Object, Object)}. This can even make DR-update flow broken in case of non-idempotent Interceptor and force users to call onGet manually as the only workaround. Also, user may want to skip Interceptor to avoid redundant entry transformation for DR updates and exchange with internal data b/w data centres which is a normal case.}}
