2017 Q3 Apache Cassandra User Survey

The 2017 Q3 Apache Cassandra User Survey conducted by ScyllaDB gathered insights from 70 expert users managing over 200 clusters and 600TB of data to understand how Apache Cassandra is utilized in production. Key findings reveal that performance, tuning, and administration are significant challenges, making up 70% of issues faced by users. Despite these challenges, more than 60% of users prefer Amazon Web Services for infrastructure, while Open Source deployments surpass DataStax in popularity. DataStax OpsCenter emerges as the leading monitoring tool, though no clear leader dominates the community. The survey highlights that more than half the deployments use Cassandra Version 2.x, with Linux packages and Docker being the favored deployment methods. Java is the predominant programming language for application development, and SSD is the preferred storage type. The survey aims to offer the Cassandra community a benchmark for making informed database decisions, with nearly half of respondents utilizing multi-tenant deployments and a significant number managing operations across multiple data centers.
