Re: [Pharo-project] Experience using multiple images as a distributed datastore?
Hi Martin, Hmm, through google it works, and removing the ? isn't enough. It is a paper on resilient distributed datasets. Lazy distributed collections, basically. http://www.cs.berkeley.edu/~matei/papers/2012/nsdi_spark.pdf Stephan
You might look at http://openreplica.org/ if you haven't. Its a python distributed object store that uses Paxos to ensure enough identical copies are preserved across machines. Instead of passing objects the messages sent to objects are sent to enough machines so that there is a quorum that have identical state. If one machine does down a replacement has the objects loaded via serialization. But most of the time its just sending messages around. Or something like that. Also probably need a faster GC.

And with OpenQwaq's Smalltalk-Python bridge you might even be able to pretend it's Smalltalk turtles all the way down, without having to attempt to re-implement Paxos? frank
