What it is

Titan is a distributed graph database designed for storing and querying massive-scale graphs with billions of vertices and edges across multi-machine clusters. It separates graph processing from storage by delegating persistence to pluggable backends (Cassandra, HBase, BerkeleyDB) while providing ACID transactions, complex graph traversals, and analytic queries at scale. Multi-module Maven monorepo: core graph engine in the root with separate modules for storage backends (titan-cassandra, titan-hbase, titan-bdb), indexing backends (titan-lucene, titan-elasticsearch, titan-solr), and a Hadoop integration layer (Faunus). Configuration examples in docs/listings/ show typical deployment…

Start here

• pom.xml: Root Maven POM defines version (1.0.1-SNAPSHOT) and top-level dependencies for all submodules
• docs/datamodel.txt: Core specification of Titan's graph model, vertex/edge properties, and schema constraints
• docs/configref.txt: Complete configuration reference for all backends and runtime tuning parameters
• BUILDING.md: Build prerequisites and Maven commands required to compile the monorepo
• docs/cassandra.txt: Primary backend integration guide for the most commonly-used storage layer

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/thinkaurelius/titan.git
cd titan
mvn clean install

Refer to BUILDING.md for Maven prerequisites (2.2.1+) and TESTING.md for test suite execution.

Daily commands:

mvn clean test

for test suite; use docs/listings/titan_cfg.txt as a base configuration, then start with a specific backend (Cassandra/HBase/BerkeleyDB) as documented in docs/cassandra.txt, docs/hbase.txt, or docs/bdb.txt respectively.…

…shortened for this brief.

Key cautions & unknowns

• Stale — last commit 4y ago
• Concentrated ownership — top contributor handles 59% of recent commits
• Titan v1.0.1 is end-of-life; JanusGraph (a fork) is the actively maintained successor—you may want that instead. Storage backend versions matter critically: Cassandra/HBase/BerkeleyDB compatibility is tight, specified…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
