Geequel Shell

Geequel Shell is a powerful CLI for running GQL queries against ONgDB. It comes bundled with each ONgDB release and can be installed independently on many systems.

What is ONgDB?

ONgDB / Owen-Gee-Dee-Bee / which stands for Open Native Graph Database, is an open source, high performance, native graph store with everything you would expect from an enterprise-ready database, including high availability clustering, ACID transactions, and an intuitive, pattern-centric graph query language. Developers use graph theory-based structures that we call nodes and relationships instead of rows and columns. For many use cases, ONgDB will provide orders of magnitude performance benefits compared to non-native graph, relational and NoSQL databases.

What is Geequel?

Geequel is ONgDB’s powerful Graph Query Language. It is a declarative, pattern matching language optimized for querying graph networks. Geequel is an implementation of openCypher®, the most widely adopted, fully-specified, and open query language for property graph databases. Geequel provides an intuitive way to work with ONgDB, a property graph, and is a great on-ramp to the Graph Query Language (GQL) ISO standard. Geequel is easy to learn and human-readable, making Geequel approachable, useful and unifying for business analysts, data scientists, software developers and operations professionals. The declarative nature of Geequel allows users to simply express the data they wish to retrieve while the underlying Geequel query runtime completes the task without burdening the user with Geequel implementation details.

How to build

Use make help (gradlew tasks) to list possible tasks. But you probably want either

make build (gradlew installDist) which will build an uber-jar and runnable script for you at geequel-shell/build/install/geequel-shell
make zip which builds an uber-jar with runnable script and packages it up for you as: out/geequel-shell.zip Note that this will run a test on the script which requires a instance of ongdb (see Integration tests below).
make untested-zip which builds the same zip file but doesn't test it. It will be placed in tmp/geequel-shell.zip.

How to run, the fast way

This clears any previously known ongdb hosts, starts a throw-away instance of ongdb, and connects to it.

rm -rf ~/.ongdb/known_hosts
docker run --detach -p 7687:7687 -e ONGDB_AUTH=none graphfoundation/ongdb:1.0
make run

How to build packages

Packages require you to have pandoc available. It should be available in your local package manager.

Then just do

make debian rpm

To test the packages you need to have Docker installed:

make debian-test rpm-test

To get the versions correct when building packages you can override some variables, for example with:

make debian pkgversion=2

See make info for a list of variables and what the results will be.

Development

Integration tests

Prerequisites for running integration tests

ONgDB server with bolt driver configured
Authentication with username ongdb and password owengee

To run

Integration tests are usually skipped when you run make test (gradlew test)

Use make integration-test (gradlew integrationTest) to specifically run integration tests.

How to run the fast way

This clears any previously known ongdb hosts, starts a throw-away instance of ongdb, and runs the integration tests against it.

rm -rf ~/.ongdb/known_hosts
docker run --detach -p 7687:7687 -e ONGDB_AUTH=ongdb/owengee graphfoundation/ongdb:1.0
make integration-test
