Sergey Kalashnikov commented on IGNITE-6387:
--------------------------------------------
Added {{NOT NULL}} constraint validation for values read from cache store
(read-through). Such values are not put into cache, a debug record is put into
log.
> SQL: NOT NULL fields validation with read-through cache store

> Key: IGNITE-6387
> URL: https://issues.apache.org/jira/browse/IGNITE-6387
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Sergey Kalashnikov
> Assignee: Sergey Kalashnikov
> Fix For: 2.3
>
>
> There is a case left unsolved during implementation of SQL NOT NULL
> constraints feature.
> It may happen so that cache update operation fails and the value loaded from
> store is put into cache.
> This value must also be validated with regards to configured NOT NULL
> constraints.
> See {{CacheConfiguration.setCacheStoreFactory()}},
> {{CacheConfiguration.setReadThrough()}}, {{QueryEntity.setNotNullFields()}}
