Today, Cloudant released BigCouch 0.4, which adds new 'zone' functionality to help users control where they put data copies. This is good news for those of you worried about the potential unexpected loss of data on the server side. Now, using zones on BigCouch can allow the same data set to be stored in different locations. The Cloudant Blog offers one example of the potential of using zones . . .
. . . our west coast cluster “Meritage” is actually spread over two different data centers in two distinct geographic regions. We use zone-support to ensure that at least one copy of all of our customers’ data exists in both locations. That way, if one location falls into the ocean or is subject to nuclear attack, our customers’ data is still safe and available. With this feature now in BigCouch, you can extend clusters across multiple locations.
BigCouch 0.4 also adds support for the replicator database to help manage multiple replications, according to the release post.
