Gaffer is a large-scale graph database framework for storing very large graphs with rich properties, supporting backends like Accumulo, HBase, and an in-memory map store. It provides high-rate ingest, query-time aggregation and summarisation, fine-grained access controls, and a REST API.

Use cases

  • store and query very large graphs with rich node and edge properties
  • continually ingest high-volume data into a graph database
  • aggregate statistical properties like counts and histograms in-database
  • analyse graph data with Apache Spark
  • serve graph queries over a REST API
  • apply fine-grained access controls to graph data

When to choose

  • you need a general-purpose operational graph database with active community support
  • your dataset is small enough for lighter graph tools like Neo4j
  • you require ongoing maintenance and updates, since the project is archived
