ParallEx is a group of common parallel collections. The intent is to make it easy to process large amounts of data.
- Create immutable parallel collections for Elixir.
- Conform to the existing Enum protocol.
- Vastly improve the performance of sequential collections of large data sets.
- Use the sequential data structures as-is where possible.
- Allow for other sequential collections to be easily parallelized.
The initial design of ParallEx is largely influenced by the design of Scala's and Clojure's parallel collections. ParallEx also references A Generic Parallel Collection Framework by Aleksandar Prokopec, Tiark Rompf, Phil Bagwell, and Martin Odersky
Currently, ParallEx supports the following data structures. More will come.
ListHashDictHashSetRange
ParallEx supports a subset of the Enum operations. More will come over time; however, some of the Enum operations are not parallelizable. The supported operations include:
reducemapfiltereachcountmember?
