Vladimir Ozerov commented on IGNITE-5482:
-----------------------------------------
One more thing - it is illegal to cache results if query contains
non-deterministic functions, such as CURTIME(). See MySQL reference as example:
https://dev.mysql.com/doc/refman/5.7/en/query-cache-operation.html
This makes previous comment about enabling cache manually with {{false}} as
default the only viable option for now.
> Implement basic caching of query results

> Project: Ignite
> Issue Type: Task
> Components: sql
> Affects Versions: 2.0
> Reporter: Alexander Paschenko

> Fix For: 2.2
>
>
> Sergi suggested that we reuse results of the same queries running
> simultaneously - i.e. if a query is being executed with the same arguments
> and flags again and again, there's no need to do actual querying of data,
> instead we can really run query once while other simultaneous runs will wait
> for those results.
> This strategy will be implemented on MAP stage of distributed query.
