Make it possible to use write sampler and read sampler in separate threads

[nosalan]

Currently, after opening the connection, it is stored in a thread local variable. It makes it impossible to use e.g. Parallel Controller to parallelize sending websocket messages and receiving them.

The problem is ilustrated in this article too:

Such feature would help in a more advanced web socket scenarios.

Hi,

Use of parallel controller does not match the design of this plugin. Just as a simple example: if a message is received on a shared connection, to which parallel thread it should be delivered?

I think most scenario’s can be implemented with combining the existing samplers and filters.

In my original scenario, I wanted to keep constant websocket sending rate from client to server, like every 200ms.
In order to avoid delays in sending I wanted to keep receiving elsewhere like in another thread.
However, I managed to implement this with currently available samplers, by having writes/reads intertwined and introduced a dynamically calculated delay.
So thins may be closed now.
Thanks.

Ok, thanks.
