Concurrent, order-preserving mapping Conduit for Haskell

conduit-concurrent-map

Provides a Conduit that maps a function concurrently over incoming elements, maintaining input order.

Note that this is not about running different parts of a conduit pipeline concurrently (see stm-conduit for something that does that). Instead, it it provides one pipeline element that processes elements concurrently internally.

Comparison to other libraries

• conduit-algorithms
  • Data.Conduit.Algorithms.Async's asyncMapC is similar but only does pure maps (a -> b) instead of monadic maps (a -> m b)
  • Data.Conduit.Algorithms.Async's asyncMapC is not async exception safe
• stm-conduit
  • Completely different goal: Connects multiple conduit components so that they run concurrently.
