# Memgraph ### Description [Memgraph](https://www.memgraph.com) 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](https://memgraph.com/docs/memgraph/connect-to-memgraph/drivers/java). 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](/data-shaper-1.21/knowing-the-data-shaper-designer/index-2/neo4j-connection.md): make sure to specify `bolt` instead of the default `neo4j` protocol * most of the [Neo4j graph output](/data-shaper-1.21/knowing-the-data-shaper-designer/pipelines/transforms/neo4j-graphoutput.md), [Neo4j output](/data-shaper-1.21/knowing-the-data-shaper-designer/pipelines/transforms/neo4j-output.md), [Cypher transforms](/data-shaper-1.21/knowing-the-data-shaper-designer/pipelines/transforms/neo4j-cypher.md) and [actions](/data-shaper-1.21/knowing-the-data-shaper-designer/workflows/actions/neo4j-cypherscript.md) (except for index manipulation, see below) seem to work correctly. ### Known issues Memgraph’s index syntax differs from the Neo4j syntax, which causes the [Neo4j index](/data-shaper-1.21/knowing-the-data-shaper-designer/workflows/actions/neo4j-index.md) and [Neo4j constraint](/data-shaper-1.21/knowing-the-data-shaper-designer/workflows/actions/neo4j-constraint.md) 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](https://memgraph.com/docs/memgraph/reference-guide/indexing) for more information on indexing. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.primeur.com/data-shaper-1.21/knowing-the-data-shaper-designer/technology/index-4.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
