Description

Yup. Please see the discussion and the reproducer class.

First put will come as CREATED then UPDATED

CacheContinuousQueryEvent [evtType=CREATED, key=CacheAccountKey{affinityAccountKey=AffinityAccountKey{accountId=8}}, newVal=Account{accountKey=DomainAccountKey{accountId=8}, name='Person#8'}, oldVal=null, partCntr=1]
CacheContinuousQueryEvent [evtType=UPDATED, key=CacheAccountKey{affinityAccountKey=AffinityAccountKey{accountId=8}}, newVal=Account{accountKey=DomainAccountKey{accountId=8}, name='Person#8'}, oldVal=Account{accountKey=DomainAccountKey{accountId=8}, name='Person#8'}, partCntr=2]

and the event will be lost. Subsequent have just 1 event and are OK:

Transform CacheContinuousQueryEvent [evtType=CREATED, key=CacheAccountKey{affinityAccountKey=AffinityAccountKey{accountId=16}}, newVal=Account{accountKey=DomainAccountKey{accountId=16}, name='Person#16'}, oldVal=null, partCntr=1]
Transform CacheContinuousQueryEvent [evtType=CREATED, key=CacheAccountKey{affinityAccountKey=AffinityAccountKey{accountId=18}}, newVal=Account{accountKey=DomainAccountKey{accountId=18}, name='Person#18'}, oldVal=null, partCntr=1]
