Cassandra and Puppet
Wednesday, March 23, 2011 at 8:00AM | Derek Stainer Constant Contact, the email marketing program has integrated social media into its capabilities by using Cassandra and Puppet, allowing Constant Contact users to easily add Facebook and Twitter links to their email marketing campaigns.
The main challenge they faced was the 10x-100x greater data volume over email with social media integration, which caused them to go to NoSQL along with Puppet and DevOps to save time and money.
Other interesting points from the article:
- With Puppet they could continiously deploy improvements to the trending and analysis tool across the cluster in a uniform way
- The machine specification selected was 3 500GB disks, 1 250GB disk, 32GB memory, No Swap, and RAID Zero Partition and Data Storage. 3 nodes were chosen as optimal, with two data centers, where each node can only use half the available disk because of RAID.
- Operational efficiencies were garnered though using Puppet with Cassandra
- There does not exist "one neck to wring" with Cassandra but again you can get paid support and training at DataStax and Constant contact used them and was happy with it
