As word about Scylla continues to spread, we’re seeing more and more downloads of our open source software. We’re not always privy to our users’ experiences, but we’re very glad when we have the opportunity to share their results. A recent example of this is from Alexys Jacob of Numberly, who shared his experience evaluating Scylla for production on his personal Blog. In the first installment of a 2-part series, he describes his preparation for a successful POC-based evaluation with the help of the ScyllaDB team.
Numberly began using MongoDB but found that MongoDB’s primary/secondary architecture hinders performance because of a loss of write throughput. Also, when you want to set up a cluster, it appears to be an abstraction added on top of replica-sets. As Alexys summarizes his MongoDB experience, “To say the least, it is inefficient and cumbersome to operate and maintain.”
Alexys also took a look at using Apache Cassandra for Numberly but was apprehensive about using a Java solution because of the heap sizes and tuning, Java overhead, and garbage collection that can temporarily stop the service. He heard about Scylla, a NoSQL database built in C++, which allows users to get more out of their machines, and decided to put it to the test.
Alexys openly provided feedback on the entire process, which is helpful to any organization evaluating a new technology. If an organization is not clear in what they are trying to achieve during a POC, problems can occur down the road when evaluating a product. Alexys also had good feedback from his experience working with the ScyllaDB staff. Here at ScyllaDB, we love feedback and always want to do better for our users.
Alexy’s blog post covers these seven lessons for evaluating Scylla:
- Have some background
- Work with a shared reference document
- Have monitoring in place
- Know when to stop
- Plan some high availability tests
- POC != production
- Make time
Get all the details in the blog post.
We’re looking forward to part two of Alexys’s series when he covers the technical aspects and details of the Scylla POC.
