This is the golang grpc client connection pool tool
Complete link state detection mechanism Every link obtained is efficient.
Basic api will not have more changes. They will be discussed on Github issues along with any bugs or enhancements
Provide a few interfaces, as efficient, stable and flexible as possible.

If it overflows for a long time you need to consider increasing the value of cap.
