-------------------------------
Summary: Short-circuit in OmKeyInfo equality check (was: Short-circuit
during the OmKeyInfo equality check)
> Short-circuit in OmKeyInfo equality check
> -----------------------------------------
>
> Key: HDDS-12822
> URL: https://issues.apache.org/jira/browse/HDDS-12822
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Ivan Andika
> Assignee: Ivan Andika
> Priority: Minor
>
> Currently OmKeyInfo#isKeyInfoSame compares the OmKeyInfo objectID last,
> although objectID is one of the most likely changed attribute. Ideally, the
> equality check should compare the attributes that are most likely changed
> first so that the results can be short-circuited faster. We can also
> prioritize primitives (int, long) attributes first, then string, then list
> (dynamic list like ACLs), and finally maps (immutable map like metadata
> should comes before mutable map like tags).
> We can try to change the ordering of OmKeyInfo#isKeyInfoSame and run some
> benchmarks to see the performance improvement.
