Writes in Cassandra — internals and performance

This talk is dedicated to a detailed analysis of how the process of writing to Apache Cassandra database occurs in terms of performance, what are the stages of requests processing, how long they take, what streams are responsible for. This talk covers the current stable version 3.11.x, but will also include information on changes in terms of writes performance recording made in version 4.0.

The targeted audience — developers and administrators that use Apache Cassandra. The talk will allow you to better understand how Cassandra is arranged internally, what determines performance of write operations and what are the bottlenecks for this type of request.
