## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)

## What it is
Titan is a scalable distributed graph database optimized for storing and querying graphs with billions of vertices and edges, supporting the Apache TinkerPop/Gremlin stack. It runs as a cluster on top of storage backends like Cassandra or HBase with indexing via Elasticsearch or Solr.

## Use cases
- store and query a graph with billions of vertices and edges
- run Gremlin traversals over a distributed graph
- build a social network or fraud-detection graph backend
- use Cassandra or HBase as a graph storage backend
- full-text search over graph properties with Elasticsearch

## When to choose
- you need a JVM-based distributed graph database with TinkerPop compatibility and are comfortable maintaining it yourself

## When to avoid
- starting a new project - the project is effectively abandoned and JanusGraph is its maintained successor
- small graphs that fit in a single-node database
- you need commercial support or active community fixes

## Facets
- artifact type: application
- maturity: abandoned
- function: database, search-engine, caching
- domain: databases, graph-processing, big-data, microservices
- platform: jvm, windows, cross-platform
- tags: graph-database, distributed, tinkerpop, gremlin, nosql, oltp, linux, macos
