The default publisher limit exceeded behavior is inconsistent between Python and Java libraries. Python "silently" skips messages while Java blocks. I'm migrating an application from Java to Python, and I was surprised the behavior to be different. How come? Both libraries use thread pools without async-io (or it's java equivalent). At the very least this inconsistency should be documented and emphasized.
