## What it is
Elassandra is a distribution of Apache Cassandra with Elasticsearch embedded in each node, providing full-text and spatial search over Cassandra tables. It offers a masterless, multi-datacenter, active/active database and search engine with JSON REST access and Kibana compatibility.

## Use cases
- add full-text search to my cassandra data
- run a masterless elasticsearch cluster with no single point of failure
- replicate search and database across multiple datacenters in active/active mode
- query and aggregate cassandra data via a JSON REST API without spark or hadoop
- use kibana dashboards on top of cassandra tables
- avoid resharding when scaling out search nodes

## When to choose
- you already run Cassandra and need advanced search, aggregation, or Kibana on that data
- you need a sharded multi-master search database with cross-datacenter replication and Cassandra repair mechanisms
- you want horizontal scaling without resharding indices

## When to avoid
- you only need plain Elasticsearch with no Cassandra dependency
- you need the latest Elasticsearch features or versions, since Elassandra tracks a forked codebase
- your workload is small enough for a standard Cassandra plus a separate Elasticsearch cluster

## Facets
- artifact type: application
- maturity: maintenance
- function: search-engine, database, http-server
- domain: databases, big-data
- platform: jvm, self-hosted
- tags: cassandra, elasticsearch, masterless, multi-datacenter, nosql, kibana, search, linux, docker
