Victoria Markman created DRILL-4286:
---------------------------------------
Summary: Have an ability to put server in quiescent mode of
operation
Key: DRILL-4286
URL: https://issues.apache.org/jira/browse/DRILL-4286
Project: Apache Drill
Issue Type: New Feature
Components: Execution - Flow
Reporter: Victoria Markman
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.
