Note
This view is available starting with V4.0.0.
Purpose
This view displays the information about all tablets in the current tenant. Each tablet replica is uniquely identified by the joint key: <TABLET_ID, SVR_IP, SVR_PORT, LS_ID>.
Columns
| Column | Type | Nullable | Description |
|---|---|---|---|
| CREATE_TIME | timestamp(6) | NO | The time when the tablet replica was created. |
| MODIFY_TIME | timestamp(6) | NO | The time when the tablet replica was last modified. |
| TABLET_ID | bigint(20) | NO | The ID of the tablet replica. |
| 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 replica belongs. |
| COMPACTION_SCN | bigint(20) unsigned | NO | The snapshot version number of the data. |
| DATA_SIZE | bigint(20) | NO | The actual size of the data, in bytes. |
| REQUIRED_SIZE | bigint(20) | NO | The size of the space allocated for the data, in bytes. The data is stored in macroblocks (2 MB), so REQUIRED_SIZE >= DATA_SIZE |
Sample query
