Slides: https://www.slideshare.net/DataStax/advances-in-cassandra-tracing-with-zipkin-michael-semb-wever-the-last-pickle-c-summit-2016 | Extending Apache Cassandra tracing to use Zipkin has opened the possibility of a single tracing view from HTTP into the Database. The work, done in CASSANDRA-10392, was completed this year and is part of a broad number of improvements in open source tracing. Together they make it easy to identify which database queries take the longest and trace how the application made them. In this talk Mick Semb Wever, Consultant at The Last Pickle, will discuss the formation of the OpenTracing Project, its goals for making tracing ubiquitous, and its work improving the way Zipkin uses Apache Cassandra. He will present examples of tracing application requests through to Cassandra reading from disk, including Zipkin tracing its own operations.
