keksmd opened a new issue, #949: URL: https://github.com/apache/incubator-graphar/issues/949
## Scope Implement the first physical format backend as a separate pure-Java module: - Parquet reads with projection and row-range execution; - capability reporting for predicate/limit pushdown; - logical GraphAr type conversion including nullable and supported list types; - test fixtures that assert both values and reported pushdown behavior. ## Acceptance - Projection/range tests prove only requested columns and rows are delivered. - Java-produced/consumed GraphAr Parquet fixtures remain compatible with C++ where the C++ toolchain is buildable. - Physical-format dependencies remain outside `graphar-info`, storage API, and graph-facing API. ## Dependencies and links - Architecture: #756 and #738. - Metadata parity: #944; C++ devcontainer gate: #945. - Storage API: #947; IO contract: #948. - This enables, but does not itself implement, the ordered-by-source reader vertical. -- This is an automated message from the Apache Git Service.
