Type Members

1.  final case class ControlStatus(availableConnectionSlots: Long, pendingConnectionSlots: Int, availableAdmissionQueueSlots: Long, availableInflightSlots: Long) extends Product with Serializable
2.  final case class ControlsConfig(maxConnections: Int = 20, queueSize: Int = 1000, maxInflight: Option[Int] = None, inflightAdmissionTimeout: Option[FiniteDuration] = None, connectionAcquireTimeout: Option[FiniteDuration] = None) extends Product with Serializable

   Configuration for concurrency controls (connection pool sizing, queue limits, and timeouts).

   Configuration for concurrency controls (connection pool sizing, queue limits, and timeouts).

   Use slick.DatabaseConfig#withControls to attach a custom config to any database config:

   val config = DatabaseConfig.forConfig[H2Profile]("db")
     .withControls(ControlsConfig(maxConnections = 10, queueSize = 500))

   maxConnections

   Maximum number of concurrent database connections.

   queueSize

   Maximum number of actions waiting for a connection slot before being rejected.

   maxInflight

   Maximum number of actions that may be in-flight at once (i.e. admitted past the queue but not yet holding a connection). Defaults to None, which means 2 * maxConnections. The effective value is always at least maxConnections.

   inflightAdmissionTimeout

   How long an action may wait to be admitted as in-flight before timing out. None means wait indefinitely.

   connectionAcquireTimeout

   How long an action may wait to acquire a connection before timing out. None means wait indefinitely.

3.  trait Database[F[_], S[_]] extends Closeable

   Effect-polymorphic database API.

   Effect-polymorphic database API.

   F[_] is the effect type used for non-streaming execution (for example cats.effect.IO or scala.concurrent.Future), and S[_] is the stream type used for streaming results.

   Concrete wrappers (for example slick.cats.Database, slick.future.Database, slick.zio.Database) delegate to an underlying Slick backend database and adapt it into their effect/stream abstractions.

4.  trait DatabaseConfig extends AnyRef

   Common interface for database configuration objects that can open a database connection.

   Common interface for database configuration objects that can open a database connection.

   Both slick.basic.BasicDatabaseConfig (Typesafe Config-based) and slick.jdbc.JdbcDatabaseConfig (programmatic JDBC) implement this trait, allowing integration facades to accept either with a single method.

5.  class SlickException extends RuntimeException

   All Exceptions that are thrown directly by Slick are of type SlickException.

   All Exceptions that are thrown directly by Slick are of type SlickException. Other Exceptions originating in non-Slick code are generally not wrapped but passed on directly.

6.  class SlickTreeException extends SlickException

   A SlickException that contains a Dumpable with more details.
