Hello,

it turns out that the problem (missing objects) was caused by cluster 
configuration issues. Both the Ignite and Cassandra cluster had one node (not 
the same VM) configured with a different time zone. Since date-time was part of 
the primary key and query parameters, there were inconsistencies in how the 
date-time was converted. Because of the combinations of where the queries where 
sent and the order in which the results arrived, the outcome appeared to be 
random.

Caveat: Make sure the clusters are consistent, particularly when date-times are 
involved.

Roger

Roger,

Yeah, that's weird and hard to tell why this happens. Obviously there is some 
kind of race condition. In any case, I would do everything correctly first, and 
then check if issue persists or not.
