Oracle In-Memory Column Storage Guide

In-Memory column storage is a feature of Oracle database that allows hot data to be stored in memory for faster query performance. By loading frequently accessed data into memory, the database can avoid reading from disk, reducing I/O latency and improving query speed. In-Memory column storage also utilizes compression and columnar storage techniques to further enhance performance and reduce memory consumption. Storing data in memory allows Oracle database to process complex queries faster, speeding up analysis and report generation.
