title: auto increment primary leaving gaps in counting
body: <p>I have got a table with auto increment primary key. This table is meant to store millions of records and I don't need to delete anything for now. The problem is, when new rows are getting inserted, because of some error, the auto increment key is leaving some gaps in the auto increment ids.. For example, after 5, the next id is 8, leaving the gap of 6 and 7. Result of this is when I count the rows, it results 28000, but the max id is 58000. What can be the reason? I am not deleting anything. And how can I fix this issue. </p>
  
  <p>P.S. I am using insert ignore while inserting records so that it doesn't give error when I try to insert duplicate entry in unique column.</p>
