@congwang - how is the performance after moving to size in MB? |

I don't have a chance to test it in data center yet. |

Currently mempool is unbounded and memory in mempool grows and settles on steady state. This causes stream manager could use a lot of memory in production. We need a mechanism to add a cap there, the heap usage of stmgr is reduced down to 10% and meanwhile performance is almost not affected at all.
This should resolve #1567
