| The driver maintains a pool of connections. The pooled connections are reused by sessions and transaction to avoid overhead added by establishing new connections every time to run a query. | ||
| The connections in the pool are created on demand. The connection pool always start with no pooled connection. New connections are created on demand by sessions and/or transactions. When sessions and/or transactions finished using connections, healthy ones are returned to the pool. These pooled connections are then reused by new sessions and transactions to execute queries. | ||

| Three connection pool related configuration settings are exposed via driver configuration, namely `maxConnectionLifetime`, `maxConnectionPoolSize` and `connectionAcquisitionTimeout`. |
There was a problem hiding this comment.
The name of the settings are following java parameter naming pattern, suggest to avoid java variables by using maximum connection lifetime, etc.
