  5. def batchedSequentialTraverse[X, M[_], S](parallelism: Int, chunkSize: Int)(xs: Seq[X])(processChunk: (Seq[X]) => M[Seq[S]])(implicit M: Parallel[M]): M[Seq[S]]

    Batched version of sequential traverse

    Batched version of sequential traverse

    Can be used to avoid overloading the database queue. Use e.g. maxDbConnections * 2 as parameter for parallelism to not overload the database queue but to make sufficient use of the existing resources.

  18. def parTraverseWithLimit[X, M[_], S](parallelism: Int)(xs: Seq[X])(processElement: (X) => M[S])(implicit M: Parallel[M]): M[Seq[S]]

  19. def repeatFlatmap[M[_], A](m: M[A], f: (A) => M[A], counter: Int)(implicit monad: Monad[M]): M[A]

    Repeatedly apply the same function to a monadic value m.

    Repeatedly apply the same function to a monadic value m. This can be used to retry until the limit counter is reached or the monad m aborts.

    The caller must ensure that the underlying data structure of the iterator is immutable

    Do not use Cats' .traverse_ methods as Cats does not specify whether the step runs sequentially or in parallel for future-like monads. In fact, this behaviour differs for different versions of Cats.

  23. def sequentialTraverse_[M[_], A](xs: Iterable[A])(step: (A) => M[_])(implicit monad: Monad[M]): M[Unit]

    The implementation of traverse in cats is parallel, so this provides a sequential alternative.
