Use faster string construction for PlanExplainerExpress::getPlanSummary

    • Query Execution
    • Fully Compatible
    • v8.0
    • 200

      The string construction here is not efficient because it reallocates a new string every for every += operator along with a copy.

      To be maximally efficient, we could have the caller pass in a StackStringBuilder to getPlanSummary() to avoid any memory allocations in most cases. Otherwise, a regular StringBuilder should be better than what exists currently.
