# Proposed changes Issue Number: close #xxx ## Problem Summary: The PR is for #10136. In that, every rowset will presist a tablet schema and use in memory by rowsetMetaPB. But When tablets and rowsets in tablet too more, memory will has a lot of pressure. So we need a way to avoid it. In this pr, it will implement a global tablet schema cache. Every rowset will hold a tablet schema sptr from cache. That mean even we has tens of thousands of rowsets, if their schema is same, there will be one schema in memory. ## Checklist(Required) 1.
