Cost of updating many small keys in Badgedb?

[kevina]

One of the arguments against storing pinning information as part of an inode () is the cost of largescale updates.

This issue is to get a handle on the cost. If nothing us to document it.

@eingenito idea of not having to update every block when a pin is updated may help make this less important,

@magik6k is this a known issue with badger?

[magik6k]

Cost of updating keys should be roughly the same as just writing new ones, so that's not really an issue. The issue is GCing old versions (afaik updates to keys just leave old versions behind to be GCed).

Got it. That should be fine given that ipfs/go-ds-badger#54 has been fixed.
