+ * Database schema required by \yii\log\DbTarget.
+ *
+ * The indexes declared are not required. They are mainly used to improve the performance
+ * of some queries about message levels and categories. Depending on your actual needs, you may
+ * want to create additional indexes (e.g. index on `log_time`).
