});

// add a connection to the connection pool
// client will either hang on to the connection or close it if it is not needed
callosumClient.newConnection(slot, socket);

Overview

TCP Client for Callosum: a self-balancing distributed services protocol. It servers as a connection pool.

Open available connections are maintained internally via two heap data structures. The min heap data structure is maintained in order to provide a connection from the pool with the lowest slot value. The max heap data structure is maintained in order to enable rapid checking and replacing of a connection with a high slot value if a new connection with a lower slot value becomes available.
