Thread safe in memory B+ Tree

Here we have implemented B-Plus Tree for data block indexing as a data system project

GrayDB is a minimal, high-performance embedded database engine written entirely in C. Inspired by the architectural simplicity of SQLite and the modular power of PostgreSQL internals, it uses its own memory-efficient B+ Tree index, open-addressing Hash Table, and a small, expressive domain-specific language (DSL) for querying.

一颗b+树的实现

This repository contains several projects that simulates, for example, file system or database manager systems etc.

经典数据结构和算法，Python实现，附带详细注释和完整测试用例。持续更新中……

A persistent storage (in file) based using B+ tree with byte-slice keys and values

A key-value persistent database that supports SQL queries over B+ and LSM trees

Most advanced key-value database written in Go, extremely fast, compatible with LSM tree and B+ tree.
