[jira] [Created] (IGNITE-16048) Extract result rows for IndexQuery sequentially from pages

Maksim Timonin created IGNITE-16048:
---------------------------------------

             Summary: Extract result rows for IndexQuery sequentially from pages
                 Key: IGNITE-16048
                 URL: https://issues.apache.org/jira/browse/IGNITE-16048
             Project: Ignite
          Issue Type: Bug
            Reporter: Maksim Timonin
            Assignee: Maksim Timonin


Currently IndexQueryProcessor extract rows from cache pages by ordered list of IndexRows. It leads to access random page for every new item. 

We can optimize this process:
 # Traverse for all IndexRow and found required pageId
 # Access every page with batch of entries
 # Put them to final list in order defined with index rows.
