JasperSoft announces reporting support for Hadoop and leading NoSQL databases.
Foursquare recently suffered a total site outage for eleven hours. The outage was caused by unexpected uneven growth in their MongoDB database that their monitoring didn't detect. The system outage was prolonged when an attempt to add a partition didn't work due to fragmentation, and required taking the database offline to compact it. Learn what happened and what responses are planned.
The first four NoSQL datastores are available as Add-ons for the Heroku PaaS (platform-as-a-service) platform. Using the Add-on system that was introduced in October 2009, CouchDB from Cloudant, Membase from NorthScale, MongoDB from MongoHQ and Redis were made available for Heroku users.
Couchio, the company founded by Damien Katz, creator of CouchDB, has announced the release of CouchDB SDK for Android, a mobile version of the document database that can be used offline.
The 2nd annual RubyConf China, this year in Shanghai, China, featured Ruby creator Matz who talked about Ruby Community and Ruby 2.0. InfoQ takes a look at the other talks and what tools and databases Ruby developers in and around China use.
In this talk from RubyFringe, Damien Katz explains what drove him to create CouchDB, why he chose Erlang, how it ended up as an Apache project and much more.
In a recent blog post, Martin Fowler, a renowned software thought leader, observed at last week's QCon that the deep freeze in thinking about databases in application architectures is thawing. The world has been stuck using RDBMS databases for every application use case, but the time has come to also consider RISC RDBMS or distributed document-oriented databases.
In a world of services, RDBMS are not the solution to every problem. Document Oriented Distributed Databases try to solve this and add a new way of storing documents. CouchDB (written in Erlang) is in its alpha stage and evolving on a regular basis. InfoQ caught up with Anthony Eden who is implementing the same concept in Ruby with RDDB.
