> Key: IGNITE-7014
> URL: https://issues.apache.org/jira/browse/IGNITE-7014

> Components: cache, sql
> Reporter: Vladimir Ozerov

> Fix For: 2.4

>
> See {{IgniteCacheOffheapManagerImpl.canUpdateOldRow}} - if cache has at least one query entity, in-place updates are not possible. This drastically reduces performance of DML and regular update (cache API) operations.
> We need to understand whether any explanation of this restriction exists. In any case, in-place updates should be allowed for SQL-enabled caches.
