[rabbitmq-discuss] publish/commit rate drops to 0 when consuming large queues from new persister

[alex chen]

Hi,

We use the new persister and tx_commit in publish.   When there are large number of messages backed 
up in the queues, starting the consumers would block the 
publish+commit.  it could take more than 20 seconds for the client to receive tx_commit_ok.

Is it possible to add an option on server side that can set the consume/publish ratio?  e.g.  ratio=2 meaning after consuming 2*N messages, server will process up to N publish messages (if there is any).

thanks.
