Chapter 11: Performance Benchmarking and Migration

In Chapter 10, Troubleshooting Issues, we learned how to troubleshoot issues with the help of metrics and logs. In this chapter, we will go over some important parameters that we should consider during performance benchmarking, how to do performance benchmarking, and important things to consider during migration. Finally, we will look at some specific examples of migrating from some traditional databases, such as PostgreSQL.

The following topics will be covered in this chapter:
