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
