Summary

Issue: Wrong caching for metric expressions apart from panel type graph in v3
According to current implementation , we are not caching queries, we are only caching expressions, we are caching if the panel type is graph, so if we are not caching single value panel type queries, we should not also be caching the result of the expression.

for eg-
If the expression is 'A+B', caching key would be '+' that dosen't consider the fact that wether A or B were same or not.

So while creating caching keys for expression , added a check if the version is not v4 then don't proceed unless its panelType: Graph

Screenshots

We are getting cached result with actual result which are vague

Affected Areas and Manually Tested Areas

Manually tested Aread ->
1.) Api -> /api/v3/query_range, tested with different panel type and checking wether we were getting correct result or not

Important

Fix caching behavior in GenerateKeys of query_builder.go to skip non-graph panel types in non-v4 versions.

• Behavior:
  • In GenerateKeys of query_builder.go, skip caching for expressions if version is not v4 and panel type is not Graph.
• Caching:
  • Ensures caching only for Graph panel type in non-v4 versions to prevent incorrect cache results for other panel types.

• Draft comment:
  The condition if params.Version != "v4" && params.CompositeQuery.PanelType != v3.PanelTypeGraph is used to prevent caching for non-graph panel types in v3. Ensure this logic is consistently applied across all relevant sections of the codebase where caching decisions are made.

2. pkg/query-service/app/queryBuilder/query_builder.go:441

• Draft comment:
  Avoid using the component/index.tsx file structure approach, as it makes it difficult to debug and find components using global search tools like VS Code.
• Reason this comment was not posted:
  Comment was on unchanged code.
