[I] [EPIC] [Parquet] Stabilize Variant support (remove the variant_experimental flag) [arrow-rs]
sdf-jkl opened a new issue, #10546:
URL: https://github.com/apache/arrow-rs/issues/10546
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
Successor to https://github.com/apache/arrow-rs/issues/6736 (initial implementation) and https://github.com/apache/arrow-rs/issues/8480 (finalization). Most of the work tracked there is done, so this epic tracks only what gates renaming `variant_experimental` to `variant` (https://github.com/apache/arrow-rs/issues/8297). Non-blocking follow-on work is tracked separately in #BBBBB.
