Module transact::scheduler

Batch scheduling with transaction execution APIs

A Scheduler is used to execute one or more Batch objects, receiving a BatchExecutionResult as a result of the execution of a Batch. A Batch contains one or more Transaction objects; each Transaction within a Batch is executed and then consolidated to generate a BatchExecutionResult.

In order for a Scheduler to execute batches, its associated SchedulerExecutionInterface must be consumed by a component responsible for iterating over the Transactions and providing ExecutionTaskCompletionNotifications back to the Scheduler via the SchedulerExecutionInterface.

Modules

• multi
  A Scheduler which runs multiple sub-schedulers. The primary purpose of the MultiScheduler is for testing; it enables running multiple schedulers in parallel to verify that they all produce the same results for a given workload.
• parallel
• serial
  A Scheduler which schedules transaction for execution one at time.

Structs

• BatchExecutionResult
  Result of executing a batch.
• ExecutionTask
  A transation and associated information required to execute it.
• InvalidTransactionResult

Enums

• ExecutionTaskCompletionNotification
• SchedulerError

Traits

• ExecutionTaskCompletionNotifier
  Allows sending a notification to the scheduler that execution of a task has completed.
• Scheduler
  Schedules batches and transactions and returns execution results.
• SchedulerFactory
  Creates new schedulers
