pub struct ConnectionPoolOptions {
    pub max_connections: Option<u32>,
    pub claim_timeout: Option<u64>,
    pub log: Option<Logger>,

}

The configuration options for a Cueball connection pool. This is required to instantiate a new connection pool.

Fields

max_connections: Option<u32>

An optional maximum number of connections to maintain in the connection pool. If not specified the default is 10.

claim_timeout: Option<u64>

An optional timeout for blocking calls (claim) to request a connection from the pool. If not specified the calls will block indefinitely.

log: Option<Logger>

An optional slog logger instance. If none is provided then the logging will fall back to using the slog-stdlog drain which is essentially the same as using the rust standard log crate.

rebalancer_action_delay: Option<u64>

An optional delay time to avoid extra rebalancing work in case the resolver notifies the pool of multiple changes within a short period. The default is 100 milliseconds.

decoherence_interval: Option<u64>

Optional decoherence interval in seconds. This represents the length of the period of the decoherence shuffle. If not specified the default is 300 seconds.

connection_check_interval: Option<u64>

Optional connection check interval in seconds. This represents the length of the period of the pool connection check task. If not specified the default is 30 seconds.
