title: What is default timeout for MongoDB operation (CRUD and aggregate)?
body: <p>I didn't find information about what is default value for executing operation in MongoDB. Some of my aggregate commands takes minutes (very large reports). It is OK for me to waiting this time, but I'm afraid to get error.</p>
  
  <p>I know, that I can set it. But a lots of my software users use their own servers. Of course with default settings.</p>
