v0.11.0-alpha

Added

• Adds an initial implementation of GPML (Graph Pattern Matching Language), following
  PartiQL RFC-0025
  and RFC-0033.
  This initial implementation includes:
  • A file format for external graphs, defined as a schema in ISL (Ion Schema Language),
    as well as an in-memory graph data model and a reader for loading external graphs into it.
  • CLI shell commands !add_graph and !add_graph_from_file for bringing
    externally-defined graphs into the evaluation environment.
  • Evaluation of straight-path patterns with simple label matching and
    all directed/undirected edge patterns.
• Adds new TupleConstraint variant, Ordered, to represent ordering in StructType. See the KDoc for more information.

Changed

• Breaking: The fields attribute of org.partiql.types.StructType is no longer a Map<String, StaticType>. It is
  now a List<org.partiql.types.StructType.Field>, where Field contains a key (String) and value (StaticType). This
  is to allow duplicates within the StructType.

Deprecated

• None

Fixed

• Fixes the ability for JOIN predicates to access the FROM source aliases and corresponding attributes.

Removed
