| == Description |
| |
| Neo4j is an open source Graph database which you can download from **https://neo4j.com/download-center/[www.neo4j.com/download-center]** |
| |
| You can use it to represent information in way that allows for really fast graph queries to be executed. For more information on these unique graph algorithms see: https://neo4j.com/docs/graph-data-science/current/algorithms/#algorithms[Neo4j Graph Algorithms] |
| |
| == Execution lineage |
| |
| You can use Neo4j to store logging and execution lineage of your workflows and pipelines. |
| The way you do this is simply by setting the variable NEO_LOGGING_CONNECTION to the name of the Neo4j Connection where you want the logging and lineage to be written to. |
| |
| The Neo4j plugin offers a separate perspective to query this logging and lineage information. For example, it allows you to quickly jump to the place where an error occurred. |
