Subject: stratified B-trees
Date: Wed, 23 Mar 2011 12:08:52 -0430 [thread overview]
Message-ID: <201103231208.52592.tierpluspluslists@gmail.com> (raw)
I just noticed this out today on the arXiv : http://xxx.lanl.gov/abs/1103.4282
The paper describes "stratified B-trees" and quoting from the abstract:
"
We describe the `stratified B-tree', which beats the CoW B-tree in every way.
In particular, it is the first versioned dictionary to achieve optimal
tradeoffs between space, query and update performance. Therefore, we believe
there is no longer a good reason to use CoW B-trees for versioned data stores.
"
The paper mentions that a company called "Acunu" is developing an
implementation.
Are these stratified B-trees something which the btrfs project could use?
