ElasticSearch 1.0 springs out: The search-oriented NoSQL database, built upon Lucene, ElasticSearch has hit version 1.0. It’s a big release with a lot of changes and a lot of new features – an API for selective snapshot/restore, federated search, aggregation, distributed percolation and software “circuit breakers” to stop some more dangerous actions from overwhelming the system. An interesting post from Found.no on ElasticSearch sums up the pros and cons (like no authentication or authorisation) places ElasticSearch in the domain of “secondary store” to be used alongside a primary database.
TokuMX 1.4: Tokutek’s “MongoDB-with-Toku-engine”, TokuMX, has hit version 1.4 and is addressing the performance of sharding and replication. Toku’s engine is reputed to be very good for particular use cases and it’s interesting to see alternative storage engines under the MongoDB infrastructure.

In an announcement. It can be downloaded from the Akaros project (or cloned from the GitHub repo) which seems to be breeding Inferno/Plan 9 with their own many-core large-smp research.
