New also records the stack trace at the point it was called
errors.New should not be cached for usages
If error checking is necessary, we should introduce an error type and use errors.Is

Summary
No longer erring out if one batch fails
Motivation
We want as many metrics to try and get written, errors may be related to things like writing duplicate time series which shouldn't stop the entire loop.
