/**
 * 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`).
