展示 Region 信息

集群中以 SchemaRegion/DataRegion 作为元数据/数据的复制和管理单元，Region 的状态和分布对于系统运维和测试有很大帮助，如以下场景：

查看集群中各个 Region 被分配到了哪些 DataNode，是否均衡
查看集群中各个 Region 被分配了哪些分区，是否均衡
查看集群中各个 RegionGroup 的 leader 被分配到了哪些 DataNode，是否均衡

当前 IoTDB 支持使用如下 SQL 展示 Region 信息：

SHOW REGIONS: 展示所有 Region 分布
SHOW SCHEMA REGIONS: 展示所有 SchemaRegion 分布
SHOW DATA REGIONS: 展示所有 DataRegion 分布
SHOW (DATA|SCHEMA)? REGIONS OF DATABASE <sg1,sg2,...>: 展示指定数据库 <sg1,sg2,...> 对应的 Region 分布

元数据分区：序列槽
数据分区：<序列槽，时间分区槽>

可以使用以下 SQL 来查询分区对应信息：

展示数据分区所在的 DataRegion

展示一个数据分区（或一个序列槽下的所有数据分区）所在的 DataRegion:

SHOW DATA REGIONID OF root.sg WHERE SERIESSLOTID=s0 (AND TIMESLOTID=t0)

其中，”SERIESSLOTID=s0”可以被替换为”DEVICEID=xxx.xx.xx“. 这样的话，sql会自动计算对应该设备id的序列槽。

同样的，“TIMESLOTID=t0”也可以被替换为“TIMESTAMP=t1”。这样，SQL会计算该时间戳对应的时间槽，也就是时间段包含该时间戳的时间槽。

示例:

IoTDB> show data regionid of root.sg where seriesslotid=5286 and timeslotid=0
+--------+
|RegionId|
+--------+
|       1|
+--------+
Total line number = 1
It costs 0.006s

IoTDB> show data regionid of root.sg where seriesslotid=5286
+--------+
|RegionId|
+--------+
|       1|
|       2|
+--------+
Total line number = 2
It costs 0.006s

展示元数据分区所在的 SchemaRegion

展示一个元数据分区所在的 SchemaRegion：

SHOW SCHEMA REGIONID OF root.sg WHERE SERIESSLOTID=s0

同样的，”SERIESSLOTID“与”TIMESLOTID“依然是可替换的。

示例:

IoTDB> show schema regionid of root.sg where seriesslotid=5286
+--------+
|RegionId|
+--------+
|       0|
+--------+
Total line number = 1
It costs 0.007s

展示序列槽下的时间槽

展示一个序列槽下的所有时间槽：

SHOW TIMESLOTID OF root.sg WHERE SERIESLOTID=s0 (AND STARTTIME=t1) (AND ENDTIME=t2)

示例:

IoTDB> show timeslotid of root.sg where seriesslotid=5286
+----------+
|TimeSlotId|
+----------+
|         0|
|      1000|
+----------+
Total line number = 1
It costs 0.007s

展示数据库的序列槽

展示一个数据库内，数据，元数据或是所有的序列槽：

SHOW (DATA|SCHEMA)? SERIESSLOTID OF root.sg

示例:

IoTDB> show data seriesslotid of root.sg
+------------+
|SeriesSlotId|
+------------+
|        5286|
+------------+
Total line number = 1
It costs 0.007s

IoTDB> show schema seriesslotid of root.sg
+------------+
|SeriesSlotId|
+------------+
|        5286|
+------------+
Total line number = 1
It costs 0.006s

IoTDB> show seriesslotid of root.sg
+------------+
|SeriesSlotId|
+------------+
|        5286|
+------------+
Total line number = 1
It costs 0.006s

迁移 Region

以下 SQL 语句可以被用于手动迁移一个 region，可用于负载均衡或其他目的。

MIGRATE REGION <Region-id> FROM <original-DataNodeId> TO <dest-DataNodeId>

示例:

IoTDB> SHOW REGIONS
