[TiFlash](https://docs.pingcap.com/tidb/stable/tiflash-overview) is a columnar storage component of [TiDB](https://docs.pingcap.com/tidb/stable). It mainly plays the role of Analytical Processing (AP) in the Hybrid Transactional/Analytical Processing (HTAP) architecture of TiDB.
TiFlash stores data in columnar format and synchronizes data updates in real-time from [TiKV](https://github.com/tikv/tikv) by Raft logs with sub-second latency. Reads from data replicas in TiFlash are guaranteed transactional consistent with Snapshot Isolation level. TiFlash utilizes the Massively Parallel Processing (MPP) computing architecture to accelerate the analytical workloads.
