Delta encoding, delta-of-delta, simple-8b, and run-length encoding applied to integer-like data with backward-scan decompression.
Distinct from Transparent Column Compression: Distinct from Transparent Column Compression: specifies the specific algorithms (delta encoding, simple-8b, run-length) for integer data, not general transparent compression.

CppGuide is a curated collection of educational resources and practical guides focused on C++ server development, Linux kernel internals, concurrent programming, network protocols, and security exploitation. It provides structured learning paths for backend developers, covering everything from interview preparation to building high-performance network servers and understanding operating system fundamentals. The guide distinguishes itself by offering in-depth, hands-on tutorials that walk through real-world implementations, including building a Redis-like server from scratch, designing custom
Encodes numeric fields using fewer bytes than native representation to reduce wire size.
RoaringBitmap is a compressed integer set library designed for memory-efficient storage and high-speed in-memory analytics. It provides a professional implementation of the Roaring Bitmap format to maintain compact representations of integer collections. The project features a standardized binary serialization format that enables the exchange of compressed bitmap data across different programming languages and hardware architectures. This allows for consistent data portability and cross-language data exchange. The library performs rapid logical set operations, including intersections, unions
Dynamically switches between bitsets, sorted arrays, and run-length encoding based on data density.
