What type of enhancement is this?

API improvement, User experience

What does the enhancement do?

We currently face several limitations with the metric engine:

  • It does not support multiple fields.
  • It only supports float64 as the data type for fields.
  • The tag column (primary keys) must be of string type.

I believe these restrictions significantly limit the potential of both the metric engine and PromQL.

We should devise a plan to remove these limitations.
