---------------------------------------
Labels: calcite2-required calcite3-required (was: )
> Calcite engine. Change TreeMap in sorted IndexSpoolNode to ArrayList
> --------------------------------------------------------------------
>
> Key: IGNITE-14816
> URL: https://issues.apache.org/jira/browse/IGNITE-14816
> Project: Ignite
> Issue Type: Improvement
> Reporter: Aleksey Plekhanov
> Priority: Minor
> Labels: calcite2-required, calcite3-required
>
> {{IgniteSortedIndexSpool}} assumes that the underlying input is already
> sorted, but the execution node creates {{TreeMap}} to find the rows (see
> {{IndexSpoolNode#createTreeSpool}}). This {{TreeMap}} can be replaced with
> {{ArrayList}} and binary search with the same efficiency for searching and
> lower costs for inserting data.
