To use a non-default Spark profile, it first needs to be imported into the Code Repository containing your transform. WebbThis method creates an Executor that uses a single worker thread operating off an unbounded queue. (Note however that if this single thread terminates due to a failure during execution prior to the shutdown, a new one will take its place if needed to execute subsequent tasks.)
