Hi Bo. You're not to know, but we have a long standing policy of not putting features into Mantis. This hasn't been
clear and has lapsed a bit.
So I cleaned up [1] a bit, which is the wiki place for feature proposals. However, any proposal should be run by this
list here. And either the proposer will have to be prepared to implement it themselves (which still doesn't guarantee
inclusion) or persuade other people to implement it (which is difficult). If they don't do these things then it will
almost certainly simply be ignored.
At some point possibly very soon I will be closing all the feature requests in the wiki and redirecting people to this
list and that wiki location.

Hello,
i put my idea about live and backup assets tables which i mentioned here
before into a Mantis.

I think that we don't really need to purge assets. Only what we need is have
unused assets, inventory folders and inventory items in separate backup tables
so most of the operations is done within small tables and even grids with rich
history can have very fast assets servers.

Needless to say, distributed garbage collection is extremely hard.
A year ago I broke out the 20 million assets OSGrid had by file size[1],
and 50% of them were<= 4KB uncompressed. With deduplication and
compression those 20 million assets would've taken up about 125GB of space
on disk. That was 3 years of stuff from tens of thousands of users. It
was easier and cheaper just to throw hardware at the problem and not worry
about it than to come up with a mechanism to cull unused assets.
Granted, that was before mesh started picking up steam, and another grid's
experience won't necessarily mirror that of OSGrid's. But it's a data
point.
