TiKV Introduction
TiKV is a highly scalable, low latency, and easy to use key-value database that delivers performance less than 10 ms at any scale.
TiKV is intended to fill the role of a unified distributed storage layer. TiKV excels at working with large-scale data by supporting petabyte-scale deployments spanning trillions of rows.
As a graduate project of the Cloud Native Computing Foundation, TiKV is originally created by PingCAP to complement TiDB.
Architecture
A TiKV cluster consists of the following components:
- A group of TiKV nodes: store key-value pair data
- A group of Placement Driver (PD) nodes: work as the manager of the TiKV cluster
TiKV clients let you connect to a TiKV cluster and use raw (simple get/put) API or transaction (with transactional consistency guarantees) API to access and update your data. TiKV clients interact with PD and TiKV through gRPC.
