 To get the most out of Workers Logs, it is recommended you log in JSON format. Workers Logs automatically extracts the fields and indexes them intelligently in the database. The benefit of this structured logging technique is in how it allows you to easily segment data across any dimension for fields with unlimited cardinality. Consider the following scenarios:
 
-| Scenario | Logging Code                                               | Event Log (Partial)                           |

 |    3     | `console.log({user_id: 123, user_email: "[email protected]"})` | `{user_id: 123, user_email: "[email protected]"}` |
 
-The difference between these examples is in how you index your logs to enable faster queries. In scenario 1, the `user_id` is embedded within a message. To find all logs relating to a particular user_id, you would have to run a text match. In scenarios 2 and 3, your logs can be filtered against the keys `user_id` and `user_email`.

 In the Workers Logs UI, logs are presented with a localized timestamp and a message. The message is dependent on the invocation handler. For example, Fetch requests will have a message describing the request method and the request URL, while cron events will be listed as cron. Below is a list of invocation handlers along with their invocation message.
