Reading from Cassandra — internals and performance

This talk is about the detailed analysis of how the process of reading from the Apache Cassandra database takes place in terms of performance, what are the stages of processing requests, how long they take, which threads are responsible for what and how caching is organized. You will learn about the current stable version 3.11.x and also about the information on the read performance changes made in version 4.0.

The targeted audience — developers and administrators using Apache Cassandra. The talk will allow you to better understand how Cassandra works internally, what determines its read performance and what bottlenecks there are for this type of request.
