  • Upgrade to TinkerPop 3.7.0
  • Support for Cassandra 4
  • (Official) support for Java 11
  • Cache performance improvements
  • Upgrade to Log4j2
  • Use mixed indices for numeric aggregations (min(), max(), mean(), sum())
  • Support TEXTSTRING mapping in Solr
  • New graph API to evaluate Gremlin scripts if JanusGraph is used embedded
  • ConfiguredGraphFactory can now create different indexes for different graphs in Elasticsearch
  • Add management API to remove ghost vertices
  • Add possibility to remove stale graph index entries
  • Improved support for Geoshapes in GraphBinary
  • Remove dependency on cassandra-all
  • Support TTL for CQL backend on Amazon Managed KeySpace
  • Improved index life-cycle. Better index management, possibility to remove indexes.
  • Support for ElasticSearch 8
  • Possibility to use dedicated ScyllaDB driver when JanusGraph is used embedded
  • Possibility to explicitly remove configuration options
  • Possibility to use ASCI String for vertex ids
  • CQL storage layer transitioned to asynchronous calls instead of a thread pool
  • Enhanced CQL storage parallelism for queries using multiple slices in the same step (multiple edge labels or multiple property keys)
  • Retrieval of SINGLE properties is now grouped in CQL queries (by default up to 20 properties for a single vertex)
  • Added possibility to group CQL queries for different vertices stored on the same token ranges or same replica sets
  • Improved batch-query (multiQuery) capabilities. Enhanced parent steps usage. Added batch-query optimisation to almost all execution steps (exception: ‘match’ step).
