[PR] Add Comet 1.0.0 release announcement blog post [datafusion-site]
andygrove opened a new pull request, #200:
URL: https://github.com/apache/datafusion-site/pull/200
This PR adds a blog post announcing the Apache DataFusion Comet 1.0.0 release, scheduled for 2026-07-31.
The post follows the same format as previous Comet release announcements. It frames 1.0.0 as a maturity/GA milestone and summarizes the notable changes merged since the 0.17.0 tag, including:
- Native scalar expression performance optimizations (`get_json_object`, `regexp_extract`, casts, string/array kernels) and Parquet metadata caching
- New expression and aggregate support (approx/exact percentile and median, `base64`, interval types, `grouping`/`grouping_id`, `array_prepend`, `split_part`, MapType support)
- Experimental accelerated PyArrow UDFs
- Iceberg 1.11 support and delete-file / exchange-reuse correctness fixes
- gzip native Parquet writes and Azure authentication
- Execution and fallback improvements (mixed partial/final aggregation, stage-based fallback, codegen dispatch)
- JDK 11 and Spark 3.4 deprecation notice (removal in 1.1.0)
- DataFusion 54 and Arrow 58.3 upgrade
Notes for reviewers:
- The post is a draft dated for the planned release date; the changelog link points at the not-yet-generated `docs/source/changelog/1.0.0.md`.
- No benchmark chart is included in this post.
- Commit/contributor counts are approximate and will be finalized at release time.
