Java agent instrumentation and suggest warm-up for slow code

[alexFilichkin]

Is your feature request related to a problem? Please describe.
We actively use AWS Snapstart for Java. However, the main challenge is understanding what code should be pre-warmed in Snapstart hook (priming). For example objectMapper should be warmed skd clients, etc.

Describe the solution you'd like
We can run lambda with a java agent that will instrument code and log the most time-consuming lines of code and advise to warm it. Maybe ideally add AI suggestions (but it's optional :) )

Describe alternatives you've considered
The alternative is to locally add system.out.println for every line and see what line of code is slow

Additional context
In this case we will have better adoption os snapstart

Hi @alexFilichkin,

thank you for the feature request! I am trying to understand better what the desired solution is.

Can you elaborate on your use-case and what exactly it is you are trying to achieve with Powertools?

We currently have an open issue to support Priming using CraC in Powertools #1588. Is your question the same?
