Profile Clojure applications before tuning database calls, allocation hot spots, serialization, or JVM runtime settings.
This section bridges the chapter overview and the detailed lessons below. For Java engineers, the practical question is how to handle profiling and tuning Clojure NoSQL applications in Clojure code at the database boundary.
| Review focus | What to check |
|---|---|
| Evidence | Measure before changing code or database settings. |
| Hot path | Focus on transformations and calls that dominate latency. |
| JVM reality | Include allocation, garbage collection, and thread behavior. |
Use the child lessons to move from concept to implementation. The section goal is to make the trade-off visible before the code hardens around a database assumption.
