The Redis® provided by KakaoCloud MemStore is based on a verified version of open-source Redis. It is a NoSQL database system that stores data in memory, optimized for fast data searches and retrieval. MemStore performs all processes required for node provisioning, such as creating operation servers and configuring networks, automatically so that users can focus on their business rather than database operations. It also offers various management functions for easy database management.
Redis® is a trademark of Redis Ltd. MemStore is based on open-source Redis® version 7.2 or lower.

Terminology
  • In-memory data store: Also referred to as an "in-memory database," it refers to a data storage technology that stores and manages data primarily in a computer system's main memory (RAM). This type of data store is designed to optimize data access and processing speed, making it suitable for applications that require real-time data access and fast processing.
  • NoSQL (Not Only SQL): A term used to describe a database management system that differs from traditional relational database management systems (RDBMS). NoSQL databases provide data storage and retrieval technologies specialized for storing and searching unstructured or large-scale distributed data, rather than using traditional tables and schemas.

Use Cases​

The Redis provided by MemStore stores data in memory rather than on disk, allowing for quick response to requests. It is therefore suitable for websites and applications with small data volumes that require high-speed request processing.

  • Any IT service sensitive to latency
  • IT services that require session management, queues, or other functions provided by a cache database
  • Services that require a non-relational database
