My suggestion is to go ahead and commit this PR with Jyothsna's change to
disable the "graceful" part of the graceful shutdown. The feature will be in
the product and people can turn it on to play with it. Then, @dvjyothsna should
file a JIRA for the improvements we discussed (enabling by default for true
servers, disabling for embedded.)
> Have an ability to put server in quiescent mode of operation

> I think drill will benefit from mode of operation that is called "quiescent"
> in some databases.
> From IBM Informix server documentation:
> {code}
> Change gracefully from online to quiescent mode
> Take the database server gracefully from online mode to quiescent mode to
> restrict access to the database server without interrupting current
> processing. After you perform this task, the database server sets a flag that
> prevents new sessions from gaining access to the database server. The current
> sessions are allowed to finish processing. After you initiate the mode
> change, it cannot be canceled. During the mode change from online to
> quiescent, the database server is considered to be in Shutdown mode.
> {code}
> This is different from shutdown, when processes are terminated.
