About Add greptimedb to OpenTelemery Collector exporter

[JasonChen86899]

Hello, greptimedb members.

I recently do something with opentelmetry collector and have an idea. Just make greptimedb to be an exporter of opentelemetry collector. opentelemetry data is all timeseries data inclulde trace metric log, so use greptimedb as backend store is a good idea and a good plan and try

If ok, I will go to opentelemetry community to make a issue or discussion

Good idea. Looks like we have to implement the OpenTelemetry protocol in frontend

https://opentelemetry.io/docs/reference/specification/protocol/otlp/

We already support many protocols https://docs.greptime.com/user-guide/clients/overview#protocols
I don't know whether the OpenTelemetry collector supports other protocols.

Thanks for your information. Let's do this work. It's kind full if you can create an issue in greptimedb and opentelemetry, then we can track the progress.

Great！Another question , I see only use request.Metric in greptimedb-client-go. How I can store tracing and log data with greptimedb . Is it just also with request.Metric or need add models like tracing or log in client library?

We currently only support metric-type data, but if you want to store log and trace data in greptimedb, you can temporarily use the metric model. You can put the data you need to query into the tag column and set the information for display only in the field column. Then, you can use SQL to perform queries.
Client-go is still in the early development stage, and there may be some incompatible changes in the near future. Thank you for your continued interest in greptimedb. If you have any questions, please feel free to contact us here at any time.

Thx a lot！Looking forward to the new features of client-go！I hope I can participate in the design and discussion of oltp or tracking and log related functions in client-go.

now two idea about this

1. add tracing and log protocol in client-go
2. add another backend build on greptimedb just like promscale which is another tsdb component.
