I’m a spatial data analyst trying to learn about options for pre-computing columns in Oracle 18c.
I've recently learned about Oracle’s In-Memory technology as a possible option:
Oracle 21c - Database In-Memory Support by Oracle Spatial
Spatial supports the use of Oracle Database In-Memory technology.
You can enable a spatial table for use with Database In-Memory by adding virtual columns, and then use operators such as SDO_FILTER to query that table without using a spatial index.
Question:
Is In-Memory a an extra-cost add-on to Oracle? Or is it included as standard functionality in all implementations of Oracle 21c Enterprise?
