Elassandra simplifies your data stack by combining the power of Elasticsearch and Apache Cassandra into a single unique solution.
No Single Point Of Failure
Elasticsearch is by design a sharded master-slave architecture. The Elasticsearch master node manages the mapping changes and only the primary shards take write operations. The replica shards are read-only and can be promoted to primary shards by the master node in case of failure or maintenance. By relying on Apache Cassandra, Elassandra is master-less and has no single point of write. All nodes can process the search requests, request a mapping update, and depending on the Cassandra replication factor, take write operations.
