Robby Grossman talked at Boston Riak meetup about Shareaholic’s migration from MongoDB to Riak and their requirements and evaluation of top contenders: HBase, Cassandra, Riak.
Why not MongoDB?
- working set needs to fit in memory
- global write lock blocks all queries despite not having transactions/joins
- standbys not “hot”
Bullet point format pros and cons for HBase, Cassandra, and Riak are in the slides.
