Evgeny Stanilovsky commented on IGNITE-13744:
---------------------------------------------
[~korlov] i merge new sql-calcite branch and mute some suspicious tests, i also
revert my old erroneous assumptions that table scan is more convenient than
index scan also with empty conditions, plz check it ?
> Calcite. Use TableSpool for IgniteNestedLoopJoin
> ------------------------------------------------

> Key: IGNITE-13744
> URL: https://issues.apache.org/jira/browse/IGNITE-13744
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Taras Ledkov
> Assignee: Evgeny Stanilovsky
> Priority: Minor
> Labels: calcite, calcite2-required, calcite3-required
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Now {{NestedLoopJoinNode}} uses internal buffer to save all rows of the right
> input.
> We have to do refactoring {{IgniteNestedLoopJoin}} to use rewind of the right
> input and use TableSpool for not rewindable inputs.
> This refactoring separates implementation the join logic from materialization
> of the right input if it is needed. In the future we can use disk offload for
> TableSpool etc.
