Mike Percy commented on FLUME-1860:
-----------------------------------

Is it that bad to have a transaction capacity? Having sanity checks is 
typically a good thing. If we keep them, I'd advocate for bumping the default 
to 10,000 and clarifying the error messages to be very clear on how to resolve 
the configuration issue.

> Transaction Capacity was primarily meant to be a memory safeguard. It ensures 
> that we don't have queues which are massive and can cause OOMs. I wonder if 
> there is a way of fixing this and making sure a malicious RpcClient cannot 
> cause OOMs by sending batches of huge sizes
