Hi,<br>.<br>To improve Drupal performance, our client has suggested to change the field types from varchars to integers in some tables.<br><br>A few tables with varchar fields are as follows:<br><br>node : type<br>permissions : perm
<br>node_access : realm<br>blocks_roles : module<br><br>(It means we are numbering node types from node/comment/page/story to 1/2/3/4..... like that)<br><br>I guess i need to change the drupal core code as well - if i change the core tables field types.
<br>I would like to know whether this is feasible or not.<br><br>And what would be the impact, if i change the data types of the core tables.<br><br><br>Thanks & Regards,<br>T.Melantias<br>
