Hi, I have a application with HTTP Source with 3 custom sinks with Rabbit Binder. One sink is custom file sink. I use Commons IO to write data to file. I am using concurrency to 200 for writing into a file. I see lot of back pressure as the Message Rate is around 54/s as to incoming is 900/s. How would I improve it? Can I configure Prefetch limit on each concurrent consumer? Can anyone help me?
