LanguageProject Introduction
Summary
TiKV is an open-source, cloud-native distributed key-value database that offers transactional consistency (ACID) at scale. It's a foundational component for building robust, scalable, and highly available data platforms and applications.
Problem Solved
Building applications that require both massive scale and strong data consistency (ACID guarantees) in a distributed environment is challenging. Traditional databases struggle with scaling horizontally while maintaining transactional integrity. TiKV solves this by providing a distributed, transactional key-value layer designed for such demanding scenarios.
Core Features
Distributed ACID Transactions
Supports distributed ACID transactions, guaranteeing data consistency across multiple nodes.
Horizontal Scalability
Achieves horizontal scalability by automatically sharding data and distributing load across clusters.
High Availability & Fault Tolerance
Employs Raft consensus algorithm for high availability and fault tolerance, automatically handling node failures.
Low Latency
Provides low-latency read and write operations for large datasets.
Tech Stack
Rust
Raft
gRPC
RocksDB

nmapnmap
Nmap is a free and open-source utility for network discovery and security auditing. It uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It is widely used by network administrators for network inventory, managing service upgrade schedules, and monitoring host or service uptime, as well as by security professionals.
