Read Original

It explains how the feature works to avoid full table scans, details the setup requirements, and reveals a significant practical drawback: the SYSAUX tablespace storage overhead can be enormous (e.g., 16GB), and statistics gathering performance can degrade severely due to internal maintenance operations.
