We have a lot of metrics(> 10000) and a lots of instances (> 1000)，how
to optimize prometheus memory usage？Thanks~
To reduce memory usage you would need to reduce the number of time
series being scraped. This is often done by sharding - different
Prometheus servers for different groups of targets or different
applications.
