Streamly, short for streaming concurrently, provides monadic streams, with a
|
|
|
|
|
simple API, almost identical to standard lists, and an in-built support for
|
|
|
|
|
concurrency. By using stream-style combinators on stream composition,
|
|
|
|
|
streams can be generated, merged, chained, mapped, zipped, and consumed
|
|
|
|
|
concurrently – providing a generalized high level programming framework
|
|
|
|
|
unifying streaming and concurrency. Controlled concurrency allows even
|
|
|
|
|
infinite streams to be evaluated concurrently. Concurrency is auto scaled
|
|
|
|
|
based on feedback from the stream consumer. The programmer does not have to
|
|
|
|
|
be aware of threads, locking or synchronization to write scalable concurrent
|
|
|
|
|
programs.

|
|
|
|
The basic streaming functionality of streamly is equivalent to that provided by
|
|
|
|
|
streaming libraries like
|
|
|
|
|
<https://hackage.haskell.org/package/vector vector>,
|
|
|
|
|
<https://hackage.haskell.org/package/streaming streaming>,
|
|
|
|
|
<https://hackage.haskell.org/package/pipes pipes>, and
|
|
|
|
|
<https://hackage.haskell.org/package/conduit conduit>.
|
|
|
|
|
In addition to providing streaming functionality, streamly subsumes the
|
|
|
|
|
functionality of list transformer libraries like @pipes@ or
|
2018-05-04 21:53:03 +03:00
|
|
|
|
<https://hackage.haskell.org/package/list-t list-t> and also the logic
|
|
|
|
|
programming library <https://hackage.haskell.org/package/logict logict>. On
|
|
|
|
|
the concurrency side, it subsumes the functionality of the
|
|
|
|
|
<https://hackage.haskell.org/package/async async> package. Because it
|
|
|
|
|
supports streaming with concurrency we can write FRP applications similar in
|
|
|
|
|
concept to <https://hackage.haskell.org/package/Yampa Yampa> or
|
|
|
|
|
<https://hackage.haskell.org/package/reflex reflex>.

For file IO, currently the library provides only one API to stream the lines
|
|
|
|
|
in the file as Strings. Future versions will provide better streaming file
|
|
|
|
|
IO options. Streamly interworks with the popular streaming libraries, see
|
|
|
|
|
the interworking section in "Streamly.Tutorial".

|
|
|
|
|
Why use streamly?
|
|
|
|
|
.
|
|
|
|
|
* /Simplicity/: Simple list like streaming API, if you know how to use lists
|
|
|
|
|
then you know how to use streamly. This library is built with simplicity
|
|
|
|
|
and ease of use as a primary design goal.
|
|
|
|
|
* /Concurrency/: Simple, powerful, and scalable concurrency. Concurrency is
|
|
|
|
|
built-in, and not intrusive, concurrent programs are written exactly the
|
|
|
|
|
same way as non-concurrent ones.
|
|
|
|
|
* /Generality/: Unifies functionality provided by several disparate packages
|
|
|
|
|
(streaming, concurrency, list transformer, logic programming, reactive
|
|
|
|
|
programming) in a concise API.
|
|
|
|
|
* /Performance/: Streamly is designed for high performance. See
|
|
|
|
|
<https://github.com/composewell/streaming-benchmarks streaming-benchmarks>
|
|
|
|
|
for a comparison of popular streaming libraries on micro-benchmarks.
