}

Configuration knobs for the LANCE client connection pool, mirroring the resilience patterns documented in Architecture §§14 and 20.

Fields

max_connections: usize

Maximum number of connections in the pool

min_idle: usize

Minimum number of idle connections to maintain

connect_timeout: Duration

Connection timeout

acquire_timeout: Duration

Maximum time to wait for a connection from the pool

health_check_interval: Duration

Health check interval (0 = disabled)

max_lifetime: Duration

Maximum connection lifetime (0 = unlimited)

idle_timeout: Duration

Idle timeout before closing a connection

auto_reconnect: bool

Enable automatic reconnection

max_reconnect_attempts: u32

Maximum reconnection attempts (0 = unlimited)

reconnect_base_delay: Duration

Base delay for exponential backoff

reconnect_max_delay: Duration

Maximum delay for exponential backoff

tls_config: Option<TlsClientConfig>

TLS configuration (None = plain TCP)
