Please describe what you are trying to do.**\n\nI want to add custom physical plan optimizer rules, written in rust, to `datafusion-python`. Now that we have the ability to share execution plans across the FFI boundary we should be able to expose this interface.\n\n**Describe the solution you'd like**\n\n- Implement FFI upstream `datafusion`\n- Expose `with_physical_optimizer_rules` and/or `with_physical_optimizer_rule`\n\n**Describe alternatives you've considered**\n\nNone\n\n**Additional context**\n\nThis will support things like https://github.com/datafusion-contrib/datafusion-distributed in `datafusion-python`\n","author":{"url":"https://github.com/timsaucer","@type":"Person","name":"timsaucer"},"datePublished":"2025-09-15T23:11:10.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/1238/datafusion-python/issues/1238"}
