Prepare MongoDB for Clojure examples by installing the database, configuring local instances, and verifying connectivity.
This section bridges the chapter overview and the detailed lessons below. For Java engineers, the practical question is how to handle MongoDB setup for Clojure development in Clojure code at the database boundary.
| Review focus | What to check |
|---|---|
| Installation | Use a repeatable local setup for examples. |
| Configuration | Know which defaults are safe only for development. |
| Connectivity | Verify the database before debugging Clojure client code. |
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.
