Hi,
We are trying to introduce a thread that monitors the creation of the trigger_file. As and when the file is created, the process that monitors postgres server needs to be notified through the inotify API.
This is to reduce the 3-4 seconds delay that exists with the current implementation in postgres. As per the current implementation, the thread checks for the existence of the file every 5 seconds. If the file got created just 1 second after the sleep, there is a wait time of 4 seconds before we know whether the file is present or not. We intend to avoid this delay by using inotify().
PostgreSQL version number you are running: postgres 9.1.5
How you installed PostgreSQL: Downloaded and compiled the sources
Does anyone have suggestions on the appropriate place to add inotify_add_watch to achieve our objective?
Thanks in advance.
Thanks in advance.
