Reference:

https://github.com/facebook/rocksdb/wiki/Read-only-and-Secondary-instances

현재 Giganto는 UI로부터의 로그 검색 혹은 Export할 때 저장 성능이 최대 1/6까지 떨어집니다.
이에 대한 대책중의 하나로 로그 검색 부분을 별도의 Read-only Instance를 활용하는게 어떨까요?

문서에 이런 내용이 있습니다.
Read-only and Secondary instances can be used to distribute read workloads and to scale read performance.

요약:

Publish, GraphQL 인터페이스에서는 read-only instance를 사용
Ingest 인터페이스에서는 read-write instance (Primary)를 사용

다행이도 우리가 사용중인 rocksdb-0.21.0에서도 read-only 모드를 지원하네요.
