I'm wondering about pbc_pool_master_workers Riak CS Stats metric. I want to clear its meaning for myself.
Is this metric means free pbc (to riak) connections in the pool or it indicates count of pbc connections established to riak without consideration of its usage and state (I mean is it checked out or not)?
I.e. if I have pool of pbc connections 64 and there is 32 tasks that trying to put some data. What value of this metric will be 64 or 32?
And what is request_pool_workers? Is it pbc_pool_master_workers + reserved connection pool?
