0.9.4

Documentation

• Javadoc 0.9.4
• Scaladoc 0.9.4

Changelog

• Graph elements are returned with the same structure, regardless of the underlying Gremlin Server and transport. (#20, #23)
• Bytecode translation now supports query parameters and is done directly, without generating intermediate GraphTraversal. (#25)
• Various translation improvements:
  • Function invocation on the right-hand side of WHERE binary expressions. (#22)
  • Variable, parameter, and null in UNWIND. (#29)
  • Cypher coalesce() function in RETURN. (#35)
  • Cypher properties() function in RETURN, plugin-only. (#37)
  • Support for UNWIND in Cosmos DB via the new flexible flavor mechanism. (#28)
• Translation optimizations:
  • Unused as() steps are removed, enabling some cases of Gremlin bulking optimization. (#31)
  • Generated map() steps with traversal arguments are inlined. (#33)

0.9.3

Javadoc

• 0.9.3

Changelog

• RETURN and WITH clauses are now translated in a uniform way. WITH should support everything that was previously only supported in RETURN, including aggregation functions and ORDER BY. (#11)
• Label and property predicates in MATCH and WHERE are now relocated next to the relevant step label. This allows filtering to happen sooner and makes it possible for Gremlin graph provider optimizations to take advantage of indexes, resulting in overall better query performance. (#15, #17, #18, #21)
• WHERE binary expression translation now supports property access on the right-hand side and constants on the left-hand side. (#6, #16)

0.9.2

Javadoc

• 0.9.2

Changelog

• Fixed RETURN of detached vertices
• Fixed nested traversal translation for Gremlin-Groovy
• Added node and relationship return value support to Cypher Gremlin Neo4j Driver

0.9.1

Javadoc

• 0.9.1

Changelog

• Upgraded to Cypher Frontend 3.3.3
• Added EXPLAIN support to all Cypher clients (#5)
• Uniform error handling in remote and in-memory Cypher clients
• Fixed classpath issues in Gremlin Server and Console plugins
