GitHub user alamb added a comment to the discussion: Does DataFusion Support JSON Path Filtering Like `jsonb_path_exists` in PostgreSQL?
You could create a function called `jsonb_path_exists` that takes a binary column and a json path string perhaps? You could take a look at how it is done https://github.com/datafusion-contrib/datafusion-functions-json There is a lower level API that lets you customize how expressions are planned, here: https://docs.rs/datafusion/latest/datafusion/logical_expr/planner/trait.ExprPlanner.html You can register them via https://docs.rs/datafusion/latest/datafusion/execution/trait.FunctionRegistry.html#method.register_expr_planner GitHub link: https://github.com/apache/datafusion/discussions/15264#discussioncomment-12523254 ---- This is an automatically sent email for github@datafusion.apache.org.
