109.1 DBMS_MEMOPTIMIZE_ADMIN Overview

The DBMS_MEMOPTIMIZE_ADMIN package provides the interface for flushing the Memoptimized Rowstore data that is buffered in the large pool to disk.

The Memoptimized Rowstore provides the following functionality:

  • Fast Ingest

    Fast ingest optimizes the processing of high-frequency, single-row data inserts. Fast ingest uses the large pool in the SGA for buffering the inserts before writing them to disk.

  • Fast Lookup

    Fast lookup enables fast retrieval of data for high-frequency queries. Fast lookup uses a separate memory area in the SGA called the memoptimize pool for buffering the data queried from tables.

The DBMS_MEMOPTIMIZE_ADMIN package provides the following operation related to fast ingest of the Memoptimized Rowstore:

  • Flush fast ingest data from the large pool to disk for all sessions.
