twitter/algebird

Algebird is a Scala library that provides algebraic data structures and functional programming abstractions for data aggregation and statistical computation. It offers core types like Monoids, Semigroups, and Rings, alongside probabilistic data structures such as Bloom Filters and HyperLogLog. The system supports distributed processing via Spark RDDs, asynchronous aggregation through utility classes, and seamless integration with Java and other Scala libraries.

This period focused on expanding the library's algebraic capabilities by introducing new data types, such as AdaptiveCache and BloomFilter, and providing Java and Scala 2.12/2.13 compatibility layers. The team also established robust property-based testing for these new structures and automated the generation of tuple aggregators to reduce boilerplate.

This period focused on expanding Algebird's capabilities for concurrent and distributed data processing, introducing asynchronous aggregation implementations and Spark RDD enrichment. The team also standardized performance measurement by migrating benchmarks to JMH and significantly enhanced the testing infrastructure with comprehensive property-based and compilation tests across core, generic, and utility modules.
