Configuration

public struct Configuration

A configuration object for connection pools.

Warning

This type has reference semantics due to ConnectionFactoryConfiguration.

  • The set of Redis servers to which this pool is initially willing to connect.

    Declaration

    Swift

    public let initialConnectionAddresses: [SocketAddress]
    Show on GitLab

  • The minimum number of connections to preserve in the pool.

    If the pool is mostly idle and the Redis servers close these idle connections, the RedisConnectionPool will initiate new outbound connections proactively to avoid the number of available connections dropping below this number.

    Declaration

    Swift

    public let minimumConnectionCount: Int
    Show on GitLab

  • The maximum number of connections to for this pool, either to be preserved or as a hard limit.

    Declaration

    Swift

    public let maximumConnectionCount: RedisConnectionPoolSize
    Show on GitLab

  • The configuration object that controls the connection retry behavior.

    Declaration

    Swift

    public let connectionRetryConfiguration: (backoff: (initialDelay: TimeAmount, factor: Float32), timeout: TimeAmount)
    Show on GitLab

  • Undocumented

    Declaration

    Swift

    public internal(set) var factoryConfiguration: ConnectionFactoryConfiguration { get }
    Show on GitLab

  • The logger prototype that will be used by the connection pool by default when generating logs.

    Declaration

    Swift

    public internal(set) var poolDefaultLogger: Logger { get }
    Show on GitLab

  • Creates a new connection configuration with the provided options.

    Declaration

    Swift

    public init(
    initialServerConnectionAddresses: [SocketAddress],
    maximumConnectionCount: RedisConnectionPoolSize,
    connectionFactoryConfiguration: ConnectionFactoryConfiguration,
    minimumConnectionCount: Int = 1,
    connectionBackoffFactor: Float32 = 2,
    initialConnectionBackoffDelay: TimeAmount = .milliseconds(100),
    connectionRetryTimeout: TimeAmount? = .seconds(60),
    poolDefaultLogger: Logger? = nil
)

    Parameters

    initialServerConnectionAddresses

    The set of Redis servers to which this pool is initially willing to connect. This set can be updated over time directly on the connection pool.
    maximumConnectionCount

    The maximum number of connections to for this pool, either to be preserved or as a hard limit.
    connectionFactoryConfiguration

    The configuration to use while creating connections to fill the pool.
    minimumConnectionCount

    The minimum number of connections to preserve in the pool. If the pool is mostly idle and the Redis servers close these idle connections, the RedisConnectionPool will initiate new outbound connections proactively to avoid the number of available connections dropping below this number. Defaults to 1.
    connectionBackoffFactor

    Used when connection attempts fail to control the exponential backoff. This is a multiplicative factor, each connection attempt will be delayed by this amount times the previous delay.
    initialConnectionBackoffDelay

    If a TCP connection attempt fails, this is the first backoff value on the reconnection attempt. Subsequent backoffs are computed by compounding this value by connectionBackoffFactor.
    connectionRetryTimeout

    The max time to wait for a connection to be available before failing a particular command or connection operation. The default is 60 seconds.
    poolDefaultLogger

    The Logger used by the connection pool itself.
