Docker Image for Titan Graph Database
Originally from apobbati
Titan is a free, open source database that is capable of processing
extremely large graphs and it supports a variety of indexing and storage backends,
which makes it easier to extend than some popular NoSQL Graph databases.
This docker image instantiates a Titan graph database that is capable of
integrating with an ElasticSearch container (Indexing) and a HBase container (Storage).
The default distribution of Titan runs on a single node, so I thought it would be helpful
if there was a modular way at runtime to hook up Titan to its dependencies.
Enter Docker. Now it is possible to run Titan and it's dependencies in separate Docker containers.
This container is using Titan 0.5.0. Please refer to
its page for more information.
Tinkerpop and Rexster
Tinkerpop is a vendor-independent API specification for
manipulating and access Graph databases.
Rexster is a service that provides protocols
for accessing a graph database. Currently it supports two protocols:
- REST over HTTP: Human-readable and good for testing - RexPro: Binary Protocol for performance
If you'd like to avoid vendor lock-in, then I'd recommend using Rexster as the API
for accessing your Graph database. It has support for popular graph databases,
so you can avoid refactoring your code. Take a look at Tinkerpop Gremlin for a
Groovy-DSL for querying graphs to see how RexPro and Gremlin provide syntactical
elegance to query graphs.
The minimum system requirements for this stack is 1 GB with 2 cores.
docker run -d --name es1 elasticsearch docker run -d --name hb1 nerdammer/hbase docker run -d -P --name mytitan --link es1:elasticsearch --link hb1:hbase mguindin/titan-rexster
8182: HTTP port for REST API
8183: RexPro for native access (Binary protocol)
8184: JMX Port (You won't need to use this, probably)
You can read more about it in the Rexster documentation.
To test out the REST API (over Boot2docker):
I've tested this container with the following containers:
- nerdammer/hbase: HBase db that works for Titan persistance - dockerfile/elasticsearch: This is the ElasticSearch Indexing backend for Titan. It provides search capabilities for Titan graph datasets.
