Code Review
This pull request adds documentation and step-by-step comments to the CachedState function in pkg/ddc/alluxio/operations/cached.go to clarify how the Alluxio cluster's cached capacity is retrieved and parsed. Feedback on these changes suggests improving the robustness of the parsing logic by replacing a redundant len(values) == 0 check with a check for len(values) < 3 to ensure that a capacity value is actually present before attempting to parse it.

The check len(values) == 0 is redundant and acts as dead code because the preceding strings.Contains(s, "Used Capacity:") check guarantees that the string s contains non-whitespace characters, meaning strings.Fields(s) will always return at least 2 elements.
To make this check robust and prevent potential out-of-bounds or parsing issues (e.g., if the line is exactly "Used Capacity:" without a value, which would result in values[len(values)-1] being "Capacity:"), we should verify that len(values) is at least 3. This ensures that there is actually a capacity value field to parse.

return cached, fmt.Errorf("failed to parse %s", s)

Thanks for adding documentation to the CachedState function, @YifeiZhang0508!
What looks good:
- The function-level doc comment is well-structured and follows Go conventions (describes behavior, documents return values). This is genuinely useful for GoDoc.
Suggestions:
-
DCO check is failing -- your commits need a
Signed-off-byline. Please amend your commit(s) withgit commit --amend -s(orgit rebase --signoffif multiple commits) and force-push. -
Consider removing the numbered inline comments (// 1., // 2., // 3., // 4.) -- the function body is short (~20 lines) and the code is self-explanatory. In Go, inline comments that simply restate what the code does tend to add noise rather than clarity. The function doc comment you added already explains the overall logic well. If you want to keep inline comments, drop the numbering and only annotate the non-obvious parts (e.g., the unit conversion step).
-
Minor nit: in the doc comment, "for returning" reads slightly awkward. Consider: "...converts the value to bytes." (dropping "for returning").
Blocking: DCO sign-off is required before this can merge.
