Coherence Performance impact based on SimpleMapIndex

Hi All,

I am getting these messages on all the nodes

Oracle Coherence EE 12.1.3.0.0 <D5> (thread=DistributedDefaultCacheWorker:4, member=1): There is no configured calculator for org.test.MyTestKeyClass; this SimpleMapIndex: Extractor=KeyExtractor(extractor=.getControlType()), Ordered=false, Footprint=0, Content=1 will estimate the index size using serialization, which could impact its performance.

I added key indexes using NamedCache.addKeyIndex like following

cache.addKeyIndex("getControlType", false);

Any idea about this message?

Regards

-Sono
