This was implemented in #880 (`53a747fe`, "feat(parquet): opt-in streaming reads for large data pages") — the PR didn't use a closing keyword, so the issue stayed open. `ReaderProperties` now has an opt-in `PageStreamingEnabled` flag that decodes eligible data pages incrementally instead of materializing the full uncompressed page buffer. Eligibility closely matches what was proposed here: V1/V2 PLAIN-encoded data pages larger than 1 MiB, of a streaming-capable unencrypted codec (UNCOMPRESSED/GZIP/BROTLI/ZSTD), for supported physical types. Every other page is read whole as before, and decoded values are unchanged either way. Closing as resolved — please open a new issue if you hit a page shape that still isn't covered. -- This is an automated message from the Apache Git Service.
