>          Issue Type: Improvement
>          Components: Connect

>
> PySpark Connect 4.3.0 applies per-RPC deadlines, {{RpcDeadlines}} of 
> {{pyspark.sql.connect.client}}: 10 minutes for each stream of a reattachable 
> {{ExecutePlan}} and each {{ReattachExecute}}, an hour for {{AnalyzePlan}} and 
> {{AddArtifacts}}, and 10 minutes for {{Config}}, {{Interrupt}}, 
> {{ReleaseSession}}, {{ArtifactStatus}}, {{CloneSession}}, {{GetStatus}} and 
> {{FetchErrorDetails}}. When the deadline of an execution's stream fires, the 
> operation continues on the server and the client opens a new 
> {{ReattachExecute}} stream to resume its results 
> ({{ExecutePlanResponseReattachableIterator}}); a {{DEADLINE_EXCEEDED}} of 
> another call raises {{SparkConnectGrpcException}}. So a call on a connection 
> that broke without an error does not wait forever.
> The Rust client sets no deadline on its calls, so such a call waits until the 
> connection fails, and a {{DEADLINE_EXCEEDED}} of an execution's stream, as 
> from a proxy, fails the execution where PySpark reattaches. Apply the 
> deadlines of PySpark 4.3.0 and reattach an execution whose stream exceeds its 
> deadline.
