Description

ownCloud uses the filecache table to propagate filechanges in the file hierarchy.
Under heavy usage this causes the table to become a bottleneck because multiple UPDATES
might wait for a lock on the same tupel. By storing the metadata directly in a
filesystems extended attributes and ACLs we can completely get rid of the filecache table.
Using existing filesystem capabilities we can scale ownCloud beyond what is currently
possible.
