WL#493: Make RTree Keys Work On Non-Spatial Fields
Affects: Server-7.1 — Status: Assigned — Priority: Medium
We have RTree keys implementation, but now it works only with spatial objects an is used only with special spatial functions like "WITHIN". RTree keys are slower, than BTree, but they are "symmetric" about keyparts. So one key could serve wide range of selects.
