Note
This view is available starting with V4.0.0.
Purpose
This view displays the information of all tablet replicas in the current tenant. Each tablet replica is uniquely identified by the joint key: <TENANT_ID, TABLET_ID, SVR_IP, SVR_PORT, LS_ID>.
Columns
| Column | Type | Nullable | Description |
|---|---|---|---|
| CREATE_TIME | timestamp(6) | NO | The creation time. |
| MODIFY_TIME | timestamp(6) | NO | The modification time. |
| TABLET_ID | bigint(20) | NO | The ID of the tablet. |
| SVR_IP | varchar(46) | NO | The IP address of the server. |
| SVR_PORT | bigint(20) | NO | The port number of the server. |
| LS_ID | bigint(20) | NO | The ID of the log stream to which the tablet belongs. |
| COMPACTION_SCN | bigint(20) unsigned | NO | The version number of the data snapshot. |
| DATA_SIZE | bigint(20) | NO | The actual size of the data. |
| REQUIRED_SIZE | bigint(20) | NO | The size of the space allocated to the data. The data is stored in macroblocks of 2 MB as the minimum unit. Therefore, REQUIRED_SIZE >= DATA_SIZE |
Sample query
Query the tablet replicas in the current tenant and display the first 10 records.
obclient [oceanbase]> SELECT * FROM oceanbase.DBA_OB_TABLET_REPLICAS LIMIT 10;
The query result is as follows:
