Scala High Performance

Open-source Scala projects categorized as High Performance

Top 6 Scala High Performance Projects

  • Akka

    Build highly concurrent, distributed, and resilient message-driven applications on the JVM

    Project mention: Modern Async Primitives on iOS, Android, and the Web | | 2023-12-06

    Kotlin also has a construct for asynchronous collections/streams. Kotlin's version of AsyncSequence is called a Flow. Just as Swift's AsyncSequence builds upon prior experience with RxSwift and Combine, Kotlin's Flow APIs build upon earlier stream/collection APIs in the JVM ecosystem: Java's RxJava, Java8 Streams, Project Reactor, and Scala's Akka.

  • incubator-pekko

    Build highly concurrent, distributed, and resilient message-driven applications using Java/Scala

    Project mention: Is akka still worth learning to be employable? | /r/scala | 2023-12-07

    Pekko is open source, has the same API. So there's no problem there.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • jsoniter-scala

    Scala macros for compile-time generation of safe and ultra-fast JSON codecs

    Project mention: The Newest Java Json Benchmark Results just dropped | /r/java | 2023-05-01

    Afaik dsl-json came up with a lot of improvements and inspired a several other libraries like JsonIter and jsonIter-scala. Jsoniter-scala by u/plokhotnyuk is probably the most optimized JSON library on the JVM at this point, and seems to power most of the Scala ecosystem. Some implementations/optimizations eventually made their way back into Jackson and other libraries.

  • Compute.scala

    Scientific computing with N-dimensional arrays

  • rtree2d

    RTree2D is a 2D immutable R-tree for ultra-fast nearest and intersection queries in plane and spherical coordinates

  • fast-string-interpolator

    Scala macro that generates ultra-fast string interpolators.
