What's Wrong?
i have a unique model table, 600w rows,when i use select * from table limit 7000000, query failed caused by memory exceed limit; use mem_tracker can see query use large memory
my be server still have 3g available memory
i think a sql without group by order by .. just scan full table data should not use too many memory, because be need not to load all data into memory from disk ,then send to client
