@yjshen based on the sample code in your io source PR, it looks like you want the following API as a consumer of datafusion: ```rust let ctx = ExecutionContext::get(); // returns global context singleton ExecutionContext::set(ctx); // updates global context singleton ``` If so, I think this pattern can be implemented entirely within a self-contained crate that can be published in crates.io. The global singleton context crate could provide a get/set API like so: ```rust let ctx = global_df_ctx::get(); global_df_ctx::set(ctx); ``` The end user experience would stay the same, but the code would be better decoupled and users can choose to opt-in to the feature by simply adding the extension crate as a dependency. -- This is an automated message from the Apache Git Service.
