Vladimir Ozerov updated IGNITE-11210:
-------------------------------------
Ignite Flags: (was: Docs Required)
> SQL: Introduce common logical execution plan for all query types
> ----------------------------------------------------------------
>
> Key: IGNITE-11210
> URL: https://issues.apache.org/jira/browse/IGNITE-11210
> Project: Ignite
> Issue Type: Task
> Components: sql
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Priority: Major
> Fix For: 2.8
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> At the moment we have a lot of various cached stuff used for different SQL
> types (prepared statements for local queries, two-step queries for
> distributed queries, update plan for DML).
> What we need instead of having multiple caches is to create common execution
> plan for every query, which will hold both DML and SELECT stuff. Approximate
> content of such a plan:
> # Two-step plan
> # DML plan
> # Partition pruning stuff
> # May be even cached physical node distribution (for reduce queries) for the
> given {{AffinityTopologyVersion}}
> # Probably {{AffinityTopologyVersion}}
> Then we will perform a single plan lookup/build per every query execution. In
> future we will probably display these plans in SQL views.
