Question

Hi wave I was wondering does SigNoz uses query engine apart from Prometheus <https github com SigNoz signoz blob main pkg query service app clickhouseReader reader go L47|https github com SigNoz signoz blob main pkg query service app clickhouseReader reader go L47> for the clickhouse db

< U02D38GBF9S> We don t use TSDB Time Series Database of Prometheus but we use promQL and alerting from prometheus because they are very powerful

Ankit Nayan · Answer

So the query service of signoz is exactly how Prometheus API is but it fetches data from ClickHouse rather than prometheus tsdb

Yash Sharma · Answer

Okay so it s more like using Prom Engine but fetching data from Clickhouse Do we use the same engine for storing traces as well

Ankit Nayan · Answer

No trace data has very different format for storage and querying It is inspired from the discussions at <https github com jaegertracing jaeger issues 1438>

Ankit Nayan · Answer

So the tracing system at SigNoz is inspired from jaeger metrics system from prometheus We shall try to standardise all inspirations after we have logs also
