-TIP: When querying indices that tend to be large (for example, `logs-*`), performance can be impacted by the number of fields being returned in the output. To optimize performance, we recommend using the {ref}/esql-commands.html#esql-keep[`KEEP`] command to specify fields that you want returned. For example, add the clause `KEEP @timestamp, user.name` to the end of your query to specify that you only want the `@timestamp` and `user.name` fields returned.
