keksmd opened a new issue, #950: URL: https://github.com/apache/incubator-graphar/issues/950
## Scope Implement the first graph-aware, pure-Java read vertical for `ordered_by_source` only: `GraphInfo` and `EdgeInfo` -> chunk/layout resolver -> offset range -> Parquet destination projection -> `neighbors(vertexId)` and streaming `scanEdges()`. The reader must use GraphAr offset and chunk semantics; it must not materialize an entire adjacency table for a small neighbor request. ## Acceptance - Test ordered source chunks and offsets against GraphAr fixtures, including nonzero vertex and edge chunks. - `neighbors` reads the corresponding `[start,end)` range and applies a limit as an IO hint. - `scanEdges` streams source/destination batches without a query engine or mandatory Arrow API. - Cross-language fixtures validate layout semantics. ## Dependencies and links - Architecture: #756. - Metadata gates: #943 and #944. - Storage: #947; IO contract: #948; Parquet backend: #949. - Remaining layouts, writer, and integrations stay out of this vertical. -- This is an automated message from the Apache Git Service.
