It may or may not be, but it doesn't help the OP, who already knows
where the file is, and just wants the full absolute path.  locate will
not help him there, especially if there are multiple files with the same
filename.ext on that filesystem.

locate has been around for many many years, certainly since at least
CentOS 4, likely much earlier.

There is (or at least, there should be) a script in /etc/cron.daily 
which updates it nightly.

You can configure locate (in /etc/updatedb.conf) with which directories
to index or not index.  Then you do not need to maintain your own
indexes, you can simply use the single system index.
