OK. Will fix this. Eclipse didn't pop it up for me.

> Project: Apache Drill
> Issue Type: Improvement
> Components: Web Server

> Priority: Major
> Fix For: 1.14.0

> Currently, as the number of profiles increase, we reload the same list of
> profiles from the FS.
> An ideal improvement would be to detect if there are any new profiles and
> only reload from the disk then. Otherwise, a cached list is sufficient.
> For a directory of 280K profiles, the load time is close to 6 seconds on a 32
> core server. With the caching, we can get it down to as much as a few
> milliseconds.
> To render the cache as invalid, we inspect the last modified time of the
> directory to confirm whether a reload is needed.
