Memgraph

Description

Memgraph is largely compatible with Neo4j and can use a lot of the Neo4j functionality in Apache Hop. Memgraph focuses on in-memory, realtime and scalable analytics.

The Memgraph compatibility with Neo4j allows you to use a lot of the Neo4j functionality in Apache Hop with Memgraph.

Run Memgraph in docker

The --bolt-server-name-for-init=Neo4j/ parameter needs to be set to allow Apache Hop to connect to a Memgraph database over the bolt protocol. More information is available in the memgraph docs.

Example command to start a Memgraph server in a container:

docker run -it -p 7687:7687 -p 7444:7444 -p 3000:3000 -e MEMGRAPH="--bolt-server-name-for-init=Neo4j/" memgraph/memgraph-platform

What works

Neo4j connections: make sure to specify bolt instead of the default neo4j protocol
most of the Neo4j graph output, Neo4j output, Cypher transforms and actions (except for index manipulation, see below) seem to work correctly. Please create a bug ticket if you find any issues.

known issues

Memgraph’s index syntax differs from the Neo4j syntax, which causes the Neo4j index and Neo4j constraint actions to fail.

Creating indexes through a Cypher action or a Cypher transform fails with an error similar to ERROR: org.neo4j.driver.exceptions.ClientException: Index manipulation not allowed in multicommand transactions..

Check the Memgraph docs for more information on indexing.
