A frequently asked question with HammerDB is when a user is using the TPROC-C workload to test database failure and failover scenarios, by deliberately killing connections or shutting down the database during a workload and then restarting it. We can also configure multiple databases in the same instance to test at the same time as well.

Key metrics like throughput, request latency, and memory utilization are essential for assessing Redis health, with tools like the MONITOR command and Redis-benchmark for latency and throughput analysis and MEMORY USAGE/STATS commands for evaluating memory. This plays a crucial role in supervising the replication process.

You can even go one step further and integrate your performance budgets with your CI/CD process, so that you not only get alerts but even break the build if a new deploy would violate any of your budgets. Integrating your budgets with your CI process is like having your security cameras trigger your guards to rush in and stop the bad guys.
