Want to replace MongoDB with an HDFS-based database in my architecture. Note that this is a new system, not a rewrite of an old one.
Are there any open-source "fast" read/write database built on HDFS with a model similar to a document-store, that can hold my regular business logic and enables an object model in Python? (E.g.: via Data Mapper or Active Record patterns) Thanks for all suggestions PS: I am using the "Big data" definition from Cloudera, i.e.: any data which expands more than one machine
