Overall Satisfaction with Cassandra

It’s one of the database platforms we offer to the development community in our organization. We have various selections when it comes to databases including DB2, SQL Server, Oracle, and hadoop for data warehousing. Cassandra becomes the choice when developers want to use a highly available NoSQL db.
  • Availability
  • Fast performance
  • Horizontal scalability
  • Memory first
  • Partition based
  • Dealing with tombstone
  • Maintenance/upgrade
  • Compaction and repair
  • High availability, which makes us use the tool
  • Partition key distribution mechanism is well defined
  • Horizontal scalability when needed for high volume days
  • Complex tombstone management
It was packaged with the vendor product we bought. Also, it’s good for high performance transactional systems. I'm part of our NoSQL team and Cassandra quickly became a favorite for developers with agile teams.
Overall, the product is a little hard to deal with when it comes to upgrading as there are always new versions released every quarter. Also, it’s backup and restore processes are still in their baby steps.
We use it for collecting user preferences on our website which can be quickly reused. It's also well suited for document ID lookup systems. It’s not good for high consistency level of information like account balance in your banking system.

Evaluating Cassandra and Competitors

Yes - Oracle and it was the decision from vendor
  • Product Usability
  • Product Reputation

I was not the decision maker in thus process however I like the easy use of OpsCenter .
Include more pilot groups ie developers to try out different features and do more stress testing.

Cassandra Implementation

  • Third-party professional services
CA and broadcom
Yes - Dev/test/prod and slow rollout when implementing in prod.
