Oracle TimesTen In-Memory Database Documentation
Release 22.1

Oracle TimesTen In-Memory Database is the world's fastest OLTP database. It is a relational in-memory database with a rich feature set. TimesTen supports SQL, standard APIs, complete ACID properties, and highly available replication mechanisms. A TimesTen database resides entirely in physical memory and is persistent and recoverable. By managing data in memory and optimizing data structures and access algorithms, database operations run efficiently, achieving dramatic gains in responsiveness and throughput. 

You can deploy TimesTen as a standalone database and a cache to a backend Oracle database. You can use the TimesTen Kubernetes Operator to deploy, manage, and monitor your TimesTen databases in a Kubernetes environment. These options provide powerful, robust, and fully supported solutions to meet your specific business and data requirements.
