I did use stackdriver for quite a while before I moved to Mimir. TBH its great that you are still sticking to opentelemetry. Stackdriver as metric storage is not even a wise option in todays world give there are some really good TSDB providers SaaS or otherwise that would do a much better job.

I moved away because of 2 primary reasons

1. The cost of stackdriver can add up with large-scale deployments or high-frequency metrics. It's essential to monitor and control usage to avoid unexpected billing.

2. I have experienced delays in metric updates, specifically at high frequency data. While the delays are usually minimal, they may not be ideal for some real-time monitoring use cases. FYI GCP on its own resources makes metrics available after 210s so you are always behind.

Going the TSDB route to reliably run storage has worked for me.
