Does pool's connection number can be adjusted dynamically based on different RPS?

How does radix's pool work

I checked the source codes, it works as below

• The pool will create all connections initial with pool.size number: https://github.com/mediocregopher/radix/blob/v3/pool.go#L359
• When use redis connection to get data, if some crtical network happens, the connection will be removed from the pool
  • This is test case for it: https://github.com/mediocregopher/radix/blob/v3/pool_test.go#L210
• refill operation will be executed periodically to add connection:
  • When do refill operation, allow some overflow
    • https://github.com/mediocregopher/radix/blob/v3/pool.go#L485
    • https://github.com/mediocregopher/radix/blob/v3/pool.go#L343
• doOverflowDrain operation will be executed periodically to delete the redundant connection:
  • If current connection number is greater than pool.size, the redundant connection will be deleted: https://github.com/mediocregopher/radix/blob/v3/pool.go#L520

(If i miss something, please tell me)

Does the pool work as below?

We expect the pool feature like below

• There should have minConnectionNumber and maxConnectionNumber configuration.
• Normally, the init connection number should be minConnectionNumber
• The connection number should be adjusted automatically according to how much the RPS against redis server
  • Under higher RPS, the connections should be created, but can't exceed maxConnectionNumber
  • Under lower RPS, the connections should be removed, but cannot be lower than the minConnectionNumber

Is it possible to make radix pool to support adjust the connection number dynamically based on RPS in future? (If already support, can share how to implement?)
