| Prefer string formatting to concatenating format arguments together, to avoid | |
| work at the log site. | |
| That is, prefer this: | |
| ```java | |
| logger.atInfo().log("processing: %s", request); | |
| ``` | |
| to this, which calls `request.toString()` even if `INFO` logging is disabled: | |
| ```java | |
| logger.atInfo().log("processing: " + request); | |
| ``` | |
