| description.long | Apache Ignite is an open-source distributed database that combines in-memory storage with persistent disk-based data management, supporting ACID transactions and SQL queries across distributed clusters. | KeyDB is an open-source database that offers significantly higher performance than Redis through multithreading while maintaining full Redis protocol compatibility. It includes advanced features like active replication, FLASH storage, and MVCC architecture for non-blocking queries. |
