Subject Re: HDFS-based database for Big and Small data?
Date Sat, 03 Jan 2015 08:28:56 GMT

Hbase, a NoSQL database of the Hadoop family, is what you says   that is built upon HDFS,
but is there really strong reason that you would move from MongoDB to Hbase? Is your data
really that huge?

As far as I tell, Hbase is extremely hard to use, hard to maintain as well. If I standood
in your position, I would choose MongoDB with no hesitate

Subject: HDFS-based database for Big and Small data?
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
