title: Sql Server ldf files growing very fast
body: <p>I am using Sql Server 2012.<br>
  My <strong>LDF</strong> files are growing very fastly.<br>
  For example,<br>
  If I try to change the data type of a 3-4 columns from varchar(10) to varchar(5), then almost <strong>4-5 GB</strong> of disk space is consumed.  </p>
  
  <p>Even, when i run simple insert queries, a significant amount of disk space is consumed.  </p>
  
  <p>Please tell me What are the possible reasons for growing ldf files so fastly?<br>
  How can I solve this issue?</p>
  
  <p>Thanks.</p>
