pooler 中文意思是什麼
pooler
解釋
普勒-
If a connection exists to a server that has disappeared, this connection can be drawn from the pool if the connection pooler has not detected the severed connection and marked it as invalid
如果存在一個與已消失的服務器的連接，如果連接池進程尚未檢測到斷開的連接並將連接標記為無效，可以從池中提取此連接。 -
If a connection exists to a server that has disappeared, it is possible for this connection to be drawn from the pool even if the connection pooler has not detected the severed connection and marked it as invalid
如果存在與已消失的服務器的連接，那麼即使連接池管理程序未檢測到已斷開的連接並將其標記為無效，仍有可能將此連接從池中取出。 -
This is the case because the overhead of checking that the connection is still valid would eliminate the benefits of having a pooler by causing another round trip to the server to occur
這種情況是因為檢查連接是否仍有效的系統開銷將造成與服務器的另一次往返，從而抵消了池進程的優勢。
