Pool
Pool is Used to manage and reuse client connections to service cluster.
Pool provides several key features:
-
General Purpose - Pool for GRPC,RPC,TCP.support RPC timeout.
-
Support Cluster - Connet to Cluster.
-
Danamic Update - Danamic update targets.
Pool runs on Linux, Mac OS X, and Windows.
Note: Random to pick a target to get one connection for loadbalance.
