    Description

      Currently the EXAMINED_ROWS column in INFORMATION_SCHEMA.PROCESSLIST is of type INT, so limited to 2^31, or about two billion max.

      When doing an UPDATE that requires a full table scan on a table with more than two billion rows, EXAMINED_ROWS value for that session goes up to 2147483647 but then stops at that value even though the query is still scanning more rows.
