Status
------
This change has been marked as submitted.
Review request for Plasma.
Repository: plasma-mediacenter
Description
-------
We started caching results from media sources due to our primary data source \
(Nepomuk) was quite slow and the experience was quite bad both for fetching media and \
searching through it. Going forward, Baloo is our primary data source, and was found \
to be quite performant. Given this, the additional complexity of maintaining a cache \
in DB is too much for the 1-2 second increase in Media Library load times.
Note that we are still able to pull in data from multiple data sources, we just won't \
store it on disk.
