-Re: Async Producer

If you're using default producer config values you can turn some knobs
there to get more performance most likely.
|max.message.size| (maybe try setting this to 2MB or 4MB)
|compression.codec (try gzip or snappy compression if you aren't already)
| |batch.size (divide max.message.size by your message size and leave
some padding in case you have a larger message: try 1000 for starters
but use a max.message.size > 2MB)
queue.size| (tune this and queue.time if the above doesn't get you where
you need to be)
Hopefully this helps!

However when I ran the async producer to publish 1 million of such messages, after a few thousands of messages (about 30000) I am getting an exception indicating that the event queue is full. I also observed that after this exception if I run the consumer, the consumer is able to consume lesser messages (less than 30000), which also indicates that some messages got lost due to the event queue being full.
