Track different stages of the execution of a transaction.

This is mostly meant for test instrumentation.

The default is a no-op implementation.

Abstract Value Members

  1. abstract def beginBackfill(): Unit

    Called after publishing the commit file but before the backfill attempt.

  2. abstract def beginDoCommit(): Unit

    Called before the first doCommit attempt.

  3. abstract def beginPostCommit(): Unit

    Called after backfill but before the postCommit attempt.

  4. abstract def createChild(): TransactionExecutionObserver

    Create a child instance of this observer for use in OptimisticTransactionImpl.split().

    Create a child instance of this observer for use in OptimisticTransactionImpl.split().

    It's up to each observer type what state new child needs to hold.

  5. abstract def preparingCommit[T](f: ⇒ T): T

    Wraps prepareCommit.

  6. abstract def startingTransaction(f: ⇒ OptimisticTransaction): OptimisticTransaction

    Wraps transaction creation.

  7. abstract def transactionAborted(): Unit

    Called once the transaction failed.

    Called once the transaction failed.

    *Note:* It can happen that transactionAborted() is called without beginDoCommit() being called first. This occurs when there is an Exception thrown during the transaction's body.

  8. abstract def transactionCommitted(): Unit

    Called once a commit succeeded.
