Query Service

Query service is the interface between forntend and databases. It is written in Golang. It will have modules for all supported databases. Query service is responsible to:

  • parse the request from Frontend
  • create relevant Clickhouse queries (and all other supported database queries)
  • parse response from databases and handle error if any
  • clickhouse response in the format accepted by Frontend

Configuration

  • Open ./constants/constants.go

    • Replace const RELATIONAL_DATASOURCE_PATH = "/var/lib/signoz/signoz.db"
      with const RELATIONAL_DATASOURCE_PATH = "./signoz.db".

  • Query Service needs below env variables to run:

    ClickHouseUrl=tcp://localhost:9001
    STORAGE=clickhouse

Build and Run locally

cd pkg/query-service
go build -o build/query-service main.go
ClickHouseUrl=tcp://localhost:9001 STORAGE=clickhouse build/query-service
