🧪 Relevant tests	No
🔒 Security concerns	No
⚡ Key issues to review	Possible Bug: The variable name hasPrintedPrepareComapct appears to be a typo. It should likely be hasPrintedPrepareCompact.
	Performance Concern: The debug logging logic in PrintPrepareCompactDebugLog method could potentially slow down the system if the logging is extensive due to the loop over object iterations and multiple lock operations.

PR Code Suggestions ✨

Category	Suggestion	Score
Maintainability	Correct a typo in the variable name to maintain consistency The variable name hasPrintedPrepareComapct contains a typo. It should be hasPrintedPrepareCompact to maintain consistency and avoid confusion. pkg/vm/engine/tae/catalog/object.go [45] -hasPrintedPrepareComapct bool +hasPrintedPrepareCompact bool Apply this suggestion Suggestion importance[1-10]: 10 Why: The suggestion correctly identifies and fixes a typo in the variable name, which is crucial for code clarity and maintainability.	10
Possible bug	Add a nil check for lastNode to prevent potential runtime panics Add a check to ensure lastNode is not nil before accessing its methods to prevent potential runtime panics. pkg/vm/engine/tae/catalog/object.go [657-658] lastNode := entry.GetLatestNodeLocked() +if lastNode == nil { + return false +} startTS := lastNode.GetStart() Apply this suggestion Suggestion importance[1-10]: 10 Why: This suggestion is essential as it addresses a potential runtime panic by adding a nil check before accessing methods on lastNode.	10
Enhancement	Simplify the function by removing redundant variables and directly returning the result Simplify the PrepareCompact function by directly returning the result of obj.meta.PrepareCompact() and removing the redundant variable. pkg/vm/engine/tae/tables/obj.go [66-70] -prepareCompact := obj.meta.PrepareCompact() -if !prepareCompact && obj.meta.CheckPrintPrepareCompact() { +if !obj.meta.PrepareCompact() && obj.meta.CheckPrintPrepareCompact() { obj.meta.PrintPrepareCompactDebugLog() + return false } -return prepareCompact +return true Apply this suggestion Suggestion importance[1-10]: 8 Why: This suggestion simplifies the function significantly, enhancing readability and reducing unnecessary code, which is beneficial for maintenance.	8
	Combine repeated conditions to reduce redundancy and improve readability Combine the repeated CheckPrintPrepareCompact condition to reduce redundancy and improve readability. pkg/vm/engine/tae/tables/aobj.go [126-143] if obj.meta.CheckPrintPrepareCompact() { obj.meta.PrintPrepareCompactDebugLog() -} -... -if obj.meta.CheckPrintPrepareCompact() { logutil.Infof("obj %v, data prepare compact failed", obj.meta.ID.String()) -} -... -if !prepareCompact && obj.meta.CheckPrintPrepareCompact() { - logutil.Infof("obj %v, data ref count > 0", obj.meta.ID.String()) + if !prepareCompact { + logutil.Infof("obj %v, data ref count > 0", obj.meta.ID.String()) + } } Suggestion importance[1-10]: 7 Why: The suggestion improves code readability and efficiency by combining repeated conditions, although it's not a critical issue.	7
