Correction-on-use and correction-on-change on Scalaris?

Hi all,

I recently have been playing with Scalaris, and in the UserDev Guide I found a reference to DKS.
Hence I'm wondering if Scalaris has implemented the features of "correction-on-use" [1] and "correction-on-change" [2], that replace the traditional stabilization mechanisms of Chord?

If not, what would be the simplest route to implement them?

Thanks, best regards!

for the ring maintenance of Scalaris is supported by a T-MAN [3] based
approach, which is a gossiping based schema that uses Cyclon [4] to
find random nodes and thereby is able to fix correlated node
failures that span more than the length of the succesor list.

As far as I know, it does not implement "correction-on-use", but
"correction-on-change" (maybe not exactly the way as described in [2]).

If you want to add that, you would roughly have to detect outdated
ring maintenance information during the lookup_aux and lookup_fin
messages and tell the ring maintenance (rm_... modules) to fix it.
