On the writer side, in io.deephaven.extensions.barrage.BarrageMessageWriterImpl , Barrage sets maxOutboundMessageSize to 100 * 1024 * 1024. We need to change the receive side to match.

Not your fault, but would be better to have a shared constant (IMO).

I feel the same way. We probably should do something nicer (maybe have the client request a max message size with the server). We will defer to a follow up PR.
