TiDB
An open-source distributed relational database developed by PingCAP. TiDB supports an HTAP architecture and is compatible with the MySQL protocol, enabling transactional and analytical workloads to be handled within the same system.
Timeline (last 90 days)
Representative HTAP implementations include TiDB, OceanBase and SingleStore, among others, and the core idea is to use the same storage with different execution engines to serve transactional and analytical queries respectively.
Representative products of HTAP include TiDB and SingleStore.
Traditional HTAP systems achieve parallel transactional and analytical processing by maintaining two data copies—row-store and column-store—within the same database engine; Oracle, TiDB, and SingleStore all adopt this approach.
New-generation OLTP databases such as Neon and TiDB have begun exploring building their storage layer on top of object storage
New-generation databases such as TiDB and CockroachDB attempt to simultaneously support both OLAP and OLTP workloads within a single system (HTAP).
以 CockroachDB、TiDB、YugabyteDB 为代表的 NewSQL 数据库通过内置 Raft 共识协议可将 failover 时间压缩到亚秒级别
TiKV, the storage engine of TiDB, uses a Multi-Raft architecture where each data shard (Region) runs an independent Raft group
