Motivation Many times in real life installations, one of the most important parameters of the system is the longest response time. Naturally, the shorter, the better. Therefore capturing the request that took a long time and understanding why it took it so long is a very critical and challenging task. Slow query tracing to the rescue!
Tracing is a ScyllaDB tool that is meant to help developers and administrators analyze internal data flows in a Scylla cluster. One example of such a flow is CQL request processing. Tracing works much as it does in Apache Cassandra, so Cassandra tracing advice that you find online should be helpful on Scylla, too.
