Closed SteNicholas closed 1 year ago

SteNicholas commented 1 year ago

TiFlash is a columnar storage component of TiDB and TiDB Cloud which 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 by Raft logs with sub-second latency. TiFlash Catalog should introduce to integrate with the metadata of TiFlash.
