Publication number: 20230342355Abstract: Techniques are described herein for an integrated in-front database cache (“IIDC”) providing an in-memory, consistent, and automatically managed cache for primary database data. An IIDC comprises a database server instance that (a) caches data blocks from a source database managed by a second database server instance, and (b) performs recovery on the cached data using redo records for the database data. The IIDC instance implements relational algebra and is configured to run any complexity of query over the cached database data. Any cache miss results in the IIDC instance fetching the needed block(s) from a second database server instance managing the source database that provides the IIDC instance with the latest version of the requested data block(s) that is available to the second instance. Because redo records are used to continuously update the data blocks in an IIDC cache, the IIDC guarantees consistency of query results.Type: ApplicationFiled: April 25, 2022Publication date: October 26, 2023Inventors: YUNRUI LI, WEI-MING HU, JUAN R.
