SequenceFactory

trait SequenceFactory extends AnyRef

A trait that provides generating ID sequence

A concrete implementation for this trait must behave like below.

  • Generate unique ID only for the given subID This means that IDs generated with different subID can be the same value. We can think subID as a namespace.
  • A Generated ID should be in the range [0, maxSequence] (both inclusive)

Behaviors that are not described above are dependent on a concrete implementation.

Abstract Value Members

  1. abstract def maxSequence: BigInt

    The maximum ID that can be generated

    The maximum ID that can be generated

    returns

    The maximum ID

  2. abstract def nextId(subId: Option[String])(implicit tenant: Tenant): Future[BigInt]

    Generate the next ID for the given sub ID

    Generate the next ID for the given sub ID

    subId

    The namespace. If it is scala.None, a default sub ID is used.

    returns

    A scala.concurrent.Future containing the generated ID
