IndraDB vs Neo4j

IndraDB: Rust graph database, inspired by Facebook's TAO, usable as an embedded library or a gRPC server. Neo4j: The default property-graph database, with Cypher, a big ecosystem and a managed cloud.

key differences

  • Neo4j is built for larger datasets (≤ 10 TB) than IndraDB (≤ 100 GB).
  • Horizontal scaling is none in IndraDB and addon in Neo4j.
  • Transactions: IndraDB offers limited ACID; Neo4j offers full.
  • Only IndraDB has json, in-memory.
  • Only Neo4j has transactions, full-text search, vector search, geospatial, change data capture.
  • IndraDB can run embedded in your application process.
