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 Druid queries (and all other supported database queries)
  • parse response from databases and handle error if any
  • build response in the format accepted by Frontend

Druid Queries

Internally we use both native and sql queries to Druid.

Configuration

Query Service needs below env variables to run:

    DruidClientUrl: http://signoz-druid-router:8888
    DruidDatasource: flattened_spans

The above values are the default ones used by SigNoz and are kept at deploy/kubernetes/platform/signoz-charts/query-service/values.yaml

Build and Run locally

cd pkg/query-service
go build -o build/query-service main.go
DruidClientUrl=xxxx DruidDatasource=flattened_spans build/query-service
