Agrona - Library to build high-performance applications in Java and C++

Agrona provides a library of data structures and utility methods that are a common need when building high-performance applications in Java and C++. It supports Buffers, Map, Sets, Cache, Queues and lot more.

Buffers - Thread safe direct and atomic for working with on and off heap memory with memory ordering semantics.
Lists - Array backed lists of int/long primitives to avoid boxing.
Maps - Open addressing and linear probing with int/long primitive keys to object reference values.
Maps - Open addressing and linear probing with int/long primitive keys to int/long values.
Sets - Open addressing and linear probing for int/long primitives and object references.
Cache - Set Associative with int/long primitive keys to object reference values.
Clocks - Clock implementations to abstract system clocks, allow caching, and enable testing.
Queues - Lock-less implementations for low-latency applications.
Ring/Broadcast Buffers - implemented off-heap for IPC communication.
Basic Agent framework.
Signal handling to support "Ctrl + c" in a server application.
Scalable Timer Wheel.
Basic code generation from annotated implementations that can vary on primitive types.
Off-heap counters implementation for application telemetry and position tracking.
Implementations of InputStream and OutputStream that can wrap direct buffers.
DistinctErrorLog: A log of distinct errors to avoid filling disks with existing logging approaches.

Eclipse Collections - Best Java Collection Framework

Eclipse Collections is a collections framework for Java. It has JDK-compatible List, Set and Map implementations with a rich API, additional types not found in the JDK like Bags, Multimaps, and set of utility classes that work with any JDK compatible Collections, Arrays, Maps, or Strings. The iteration protocol was inspired by the Smalltalk collection framework. It maximizes the power of Java 8 Lambda expressions and method references with rich APIs directly available on your collections.

Boon - Low Ceremony. High Productivity. A real boon to Java to developers!

The main goal of Boon is to reduce the productivity delta between Java and Python/Groovy/Ruby. The idea is to just create a lower ceremony APIs. Less Java like APIs, and more getting things done quickly APIs. If reading a file takes one line of code in Ruby/Python/Groovy, then it will also in Java. If slice notation is part of those language, then Boon will have it to.

DynamicData - Reactive collections based on Rx.Net

Dynamic Data is a portable class library which brings the power of Reactive Extensions (Rx) to collections.Rx is extremely powerful but out of the box provides nothing to assist with managing collections. In most applications there is a need to update the collections dynamically. Typically a collection is loaded and after the initial load, asynchronous updates are received. The original collection will need to reflect these changes. In simple scenarios the code is simple. However, typical applications are much more complicated and may apply a filter, transform the original dto and apply a sort. Even with these simple every day operations the complexity of the code is quickly magnified. Dynamic data has been developed to remove the tedious code of dynamically maintaining collections. It has grown to become functionally very rich with at least 60 collection based operations which amongst other things enable filtering, sorting, grouping, joining different sources, transforms, binding, pagination, data virtualisation, expiration, disposal management plus more.

Trove - High performance collections for Java

Trove provides fast, lightweight implementations of the java.util Collections API. These implementations are designed to be pluggable replacements for their JDK equivalents. This gap in the JDK is often addressed by using the "wrapper" classes (java.lang.Integer, java.lang.Float, etc.) with Object-based collections. For most applications, however, collections which store primitives directly will require less space and yield significant performance gains.

Koloboke - Java Collections till the last breadcrumb of memory and performance

Koloboke aims to replace the standard Java collections and streams with more efficient implementations. The current version of Koloboke focuses on replacing java.util.HashSet and java.util.HashMap. It provides a complete set of primitive type implementations for each collection. Its able to avoid the expensive boxing/unboxing of primitives and saves memory for boxed primitive objects. It is the fastest and the most memory efficient library implementing hash maps and sets.

immutable-js - Immutable persistent data collections for Javascript which increase efficiency and simplicity

Immutable data cannot be changed once created, leading to much simpler application development, no defensive copying, and enabling advanced memoization and change detection techniques with simple logic. Persistent data presents a mutative API which does not update the data in-place, but instead always yields new updated data.

gota - Gota: DataFrames and data wrangling in Go (Golang)

This is an implementation of DataFrames, Series and data wrangling methods for the Go programming language. The API is still in flux so use at your own risk.The term DataFrame typically refers to a tabular dataset that can be viewed as a two dimensional table. Often the columns of this dataset refers to a list of features, while the rows represent a number of measurements. As the data on the real world is not perfect, DataFrame supports non measurements or NaN elements.

icepick - Utilities for treating frozen JavaScript objects as persistent immutable collections

Utilities for treating frozen JavaScript objects as persistent immutable collections. Object.freeze() is a quick and easy way to get immutable collections in plain JavaScript. If you recursively freeze an object hierarchy, you have a nice structure you can pass around without fear of mutation. The problem is that if you want to modify properties inside this hierarchical collection, you have to return a new copy with the properties changed.

Tape - A lightning fast, transactional, file-based FIFO for Android and Java.

A lightning fast, transactional, file-based FIFO for Android and Java. QueueFile is a lightning-fast, transactional, file-based FIFO. Addition and removal from an instance is an O(1) operation and is atomic. Writes are synchronous; data will be written to disk before an operation returns. The underlying file is structured to survive process and even system crashes and if an I/O exception is thrown during a mutating change, the change is aborted.
