----------------------------------------
Summary: MVCC: Optimize filter usage in MvccUpdateDataRow.
Key: IGNITE-9689
URL: https://issues.apache.org/jira/browse/IGNITE-9689
Project: Ignite
Issue Type: Improvement
Reporter: Andrew Mashenkov
PutIfAbsent and all Replace operation uses filter for previous values checks.
When filter has provided then we have to retrieve full row (instead of header)
just to apply the filter.
However, in most of cases filter doesn't need a value itself, but just a fact
if previous value exists.
There is unused class
org.apache.ignite.internal.processors.cache.CacheOperationFilter enum that can
be used for optimization. We can just compare filter type and visitor
resultType to make a decision in CacheDataStore.mvccUpdate\mvccRemove methods.
