Tinykv
TinyKV 是一个分布式键值存储，旨在跨多个节点存储和检索数据，具有高可用性。它作为一个分布式数据库系统，包含一个专用的键值存储引擎，用于在单个节点上进行原始数据持久化和检索。
该项目包含一个 Raft 共识引擎，以确保集群服务器之间的数据一致性和容错能力。它还具有一个分布式事务管理器，用于协调原子提交和并发控制，以维护分片之间的数据完整性。
该系统涵盖了集群成员管理（包括领导者选举）和数据分片以平衡负载。它实现了分布式事务管理和基于复制的共识引擎以保持状态稳定性。
Features
- Distributed Key-Value Stores - Provides a distributed key-value store for high-availability data storage and retrieval across multiple nodes.
- Consensus Engines - Features a dedicated consensus engine to maintain fault tolerance and state consistency across the cluster.
- Distributed Atomic Transactions - Coordinates distributed atomic transactions to ensure data integrity across multiple database shards.
- Storage Engines - Incorporates a low-level storage engine for raw data persistence and retrieval on individual nodes.
- Standalone Servers - Provides a standalone key-value store with a dedicated storage engine and request handlers.
- Log-Structured Merge-Trees - Uses a Log-Structured Merge-Tree storage engine to optimize write throughput via sequential disk operations.
- Raft Consensus Implementations - Implements the Raft consensus protocol to ensure consistent state replication and leader election.
- Distributed Transaction Coordinators - Ships a distributed transaction manager to coordinate atomic commits and concurrency control.
- Distributed Transaction Management - Implements distributed transaction management using concurrency control and atomic commit protocols.
- Cluster Range Partitioning - Organizes the keyspace into contiguous ranges assigned across nodes to balance data loads.
- Cluster Load Balancing - Balances load and maintains stability by redistributing data shards and managing leader elections.
- Dynamic Cluster Membership Management - Manages dynamic cluster membership including leadership changes and data sharding.
- Optimistic Concurrency Control - Employs optimistic concurrency control to manage parallel transactions and verify conflicts during commit.
- Node Failure Detection - Implements heartbeat-based monitoring to detect node failures and trigger leader elections.
- Two-Phase Commit Protocols - Provides a two-phase commit protocol to guarantee atomic transactions across distributed shards.
