Sorry for the unclear response. 1) We use TerarkDB under a distributed SQL database and TerarkDB helps to store its pages (16KB page), its one of the most widely used SQL database inside Bytedance. 2) We use TerarkDB under a Redis compatible distributed cache system to store raw key value pairs.

Almost all kinds of workloads are here since TerarkDB runs under too many database clusters (each cluster only serves a single application)
