Subject RE: Missing object when loading from Cassandra with multiple queries
Date Wed, 02 Aug 2017 20:28:05 GMT

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.

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.
