Sorry I should have posted more code. I am using it: I am converting the
future into a scalaz.Task and then sequencing a Seq[Task[T]] to get a
Task[Seq[T]] . However the ask is not sending the message, it's trivial to
detect because wrapped into the LoggingReceive the receive method of my
target actor.
val batchesInsertionResult = batches map {
recordBatch => recordBatch map {
records =>
val successes = records collect { case \/-(x) => x }
val failures = records collect{ case -\/(x) => x}
val insertionResult = persistance flatMap {
x => x.ask(UpdateIntradayRecordsRequest(successes))(timeout)
}
asTask(insertionResult) flatMap{
case x:IntradayRecordsUpdateResult => Task now
(successes,failures,\/-(x))
case other => Task now (successes,failures, -\/( new
IllegalArgumentException(s"The result of injection " s"of $successes is
$other, which is not of expected type IntradayRecordsUpdateResult ")))
}
}
}
val insertionResult = for {
r1 <- batchesInsertionResult
r2 <- Task gatherUnordered r1.toSeq
} yield {
val parseIntradayBatchResult = r2.zipWithIndex.map {
case (entry,idx) =>
ParseIntradayRecordBatchResult(entry._1,entry._2,idx,entry._3)
}
ParseIntradayRecordResult(folder, parseIntradayBatchResult)
}
insertionResult.runAsync{
case \/-(x)=> requestor ! x
case -\/(y) => println("hello world")}
