The open source database and search engine for multi-cloud applications

Elassandra simplifies your data stack by integrating Elasticsearch® into Apache Cassandra®.

Cross Datacenter Replication

Apache Cassandra supports asynchronous multi-datacenters replication and various mechanisms to repair lost data. By closely integrating Elasticsearch with Cassandra, Elassandra provides search features on many datacenters.

Scale On-Demand

When you need to increase read/write throughput, Elassandra automatically re-shards your Elasticsearch indices as new machines are added, allowing you to smoothly scale-out to fit your business needs without down-time or heavy maintenance operations requirements.

Real-Time Analytics

By indexing cassandra data into Elasticsearch, Kibana will allow you to get continuous and real-time data visualization of your applications.

A Masterless Architecture

By using a distributed transaction, Elassandra removes the single point of failure of Elasticsearch to manage its configuration.

A Reliable Primary Datastore

Cassandra is designed for write-intensive workloads, hence, making Elassandra suitable for applications where a large amount of data is to be inserted (such as infrastructure logging, IOT, or events). So, Elasticsearch indices can be rebuilt whenever needed using the Cassandra tables without the creation of data duplication.

Continous Operations in the Cloud

Failover-based approaches do not truly achieve high availability as far as write operations are concerned. Thanks to its multi-master design, Elassandra is always available either when a server/container fails or restarts because of some maintenance operations.
