| 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. | etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. It gracefully handles leader elections during network partitions and can tolerate machine failure. |
