title: Do i need to reindex the table in mysql?
body: <p>I have a table in mysql with a lot of INSERT and SELECT at every second. And there is a bulk delete of some older data once in a day. Do I need to reindex the table after delete? I want to increase the performance. Can anybody suggest some tips? Using 'innodb' as engine. Do I need to change it? I think its better for concurrent insert and select. pls give your suggestions. Do I need reindexing?</p>
  
  <p>Thanks in advance.. </p>
