RocksDB?

What is RocksDB?

RocksDB is an embeddable persistent key-value store for fast storage. RocksDB can also be the foundation for a client-server database but our current focus is on embedded workloads.
RocksDB builds on LevelDB to be scalable to run on servers with many CPU cores, to efficiently use fast storage, to support IO-bound, in-memory and write-once workloads, and to be flexible to allow for innovation.

Supersonic Query Engine

Introduction

Supersonic is an ultra-fast, column oriented query engine library written in C++. It provides a set of data transformation primitives which make heavy use of cache-aware algorithms, SIMD instructions and vectorised execution, allowing it to exploit the capabilities and resources of modern, hyper pipelined CPUs. It is designed to work in a single process.
Supersonic is intended to be used as a back-end for various data warehousing projects. The functionalities it provides are:

• speed
• cache consciousness
• instruction pipelining
• SIMD use
• efficient memory allocation
• custom data structures

• reliability
• failure handling
• high test coverage (under development)

• robustness
• support for standard columnar database operations
• a wide range of specialised expressions (including many math, string and date manipulation functionalities)
