Is it possible to make asynchronous calls to a stored procedure in VoltDB (an insert in a custom Java Stored procedure) using the Python client?
It looks like it isn't supported but is there a way to not wait for the response, or will I have to move to the Java client for async support?
The VoltDB python client does not support asynchronous calls. It may be possible to make calls from a multi-threaded python application, but we've never tested that, so I don't want to lead you into uncharted waters.
The java, C++, and Go clients support asynchronous calls.
If you're mainly trying to do fast inserts, you might leverage csvloader and you could probably execute csvloader from within a python application, but that's probably not what you're looking to do.
