[jira] [Updated] (ARROW-9425) [Rust][DataFusion] Make
ExecutionContext sharable between threads
[ https://issues.apache.org/jira/browse/ARROW-9425?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jorge updated ARROW-9425:
-------------------------
Description:
I have been playing with pyo3 to ship and call this library directly from Python, and the current ExecutionContext can't be used within Python with threads due to the usage of `Box<dyn TableProvider>` on `datasources`, i.e. no `Sync` nor `Send`.
This issue likely affects integration of DataFusion with other libraries.
I propose that we allow ExecutionContext to be sharable between threads, e.g. using {{Box<dyn TableProvider + Send + Sync>}}.
