This blog post addresses FUD (Fear, Uncertainty, and Doubt) directed at Couchbase by DataStax. The author argues that the best way to deal with FUD is to address it directly, rather than ignoring or dismissing it. However, some claims made about Couchbase in the original post are misleading or incorrect, such as its handling of asynchronous writes and performance characteristics. In contrast, DataStax Enterprise (Apache Cassandra) also has its own strengths and weaknesses, including its use of commitlog and journaling to manage consistency and availability. The author provides recommendations for benchmarking distributed databases, including avoiding benchmarks with virtual machines, shared storage, or inadequate load settings.
