async postCommit(respData) → {*}

tx-api.js, line 90

Called after the transaction commits (and ONLY if it commits successfully). May alter the response by returning a new response value, or throwing RequestDone.

Parameters:

Name	Type	Description
respData	*	the response data

Returns:

* - the (possibly updated) response data

async preCommit(respData) → {*}

tx-api.js, line 80

Called just before the transaction ATTEMPTS to commit. May alter the response by returning a new response value, or throwing RequestDone. Throwing an error will be propagated and handled by Transaction.run(), and will prevent the transaction from committing (unless the error is retryable).

Parameters:

Name	Type	Description
respData	*	the response data

Returns:

* - the (possibly updated) response data

async preTxStart()

tx-api.js, line 68

Called just before the transaction starts. Useful to do async computation outside the transaction (reducing the window for contention).
