To use both the raw and transactional APIs in the same cluster, please enable API V2.
Interact with TiKV using the raw key-value API or the transactional key-value API.
TiKV offers two APIs that you can interact with:
|Raw||A low-level key-value API to interact directly with individual key-value pairs||Single key||Your application requires low latency and does not involve distributed transactions.|
|Transactional||A high-level key-value API to provide ACID semantics.||Multiple keys||Your application requires distributed transactions.|
TiKV provides the following clients developed in different programming languages:
