+`rowsets` 是doris内置的一张系统表，存放在`information_schema`数据库下。通过 `rowsets` 系统表可以查看各个`BE` 当前rowsets情况。
+
+rowsets表结构为：
+```sql
+MySQL [(none)]> desc information_schema.rowsets;
++------------------------+------------+------+-------+---------+-------+
+| Field | Type | Null | Key | Default | Extra |
++------------------------+------------+------+-------+---------+-------+
+| BACKEND_ID | BIGINT | Yes | false | NULL | |
+| ROWSET_ID | VARCHAR(*) | Yes | false | NULL | |
+| TABLET_ID | BIGINT | Yes | false | NULL | |
+| ROWSET_NUM_ROWS | BIGINT | Yes | false | NULL | |

+| NEWEST_WRITE_TIMESTAMP | BIGINT | Yes | false | NULL | |
++------------------------+------------+------+-------+---------+-------+
+```
+backends 系统表展示出来的信息基本与 `show backends` 语句展示出的信息一致。但是backends系统表的各个字段类型更加明确，且可以利用backends 系统表去做过滤、join等操作。
