Description

The default producer value for a Bridge (clustered or not) is -1, meaning unlimited.

We had seen scenarios where the target and source runs out of memory when running on slow networking or disk.

I have looked into changing the implementation to back pressure the networking, however values are added into an Executor (through an Actor), and we the alternate back pressure would mean to add a new value to this executor, binding it towards the network.

Which is a whole circle round back to the same problem... managing credits.

instead of adding a new value, I will change the default value for Bridges which would have the same impact.
