Use YSQL yb_local_tablets view to fetch the metadata for YSQL, YCQL, and system tablets of a node. This view returns the same information that is available on <yb-tserver-ip>:9000/tablets.
While debugging a system with Active Session History, the tablet_id column of this view can be joined with the wait_event_aux column of the yb_active_session_history view. For example, see Detect a hot shard.
The columns of the yb_local_tablets view are described in the following table.
| Column | Type | Description |
|---|---|---|
| tablet_id | text | 16 byte UUID of the tablet. |
| table_id | text | 16 byte UUID of the table which the tablet is part of. |
| table_type | text | Type of the table. Can be YSQL, YCQL, System, or Unknown. |
| namespace_name | text | Name of the database or the keyspace. |
| ysql_schema_name | text | YSQL schema name. Empty for YCQL, System, and Unknown table types. |
| table_name | text | Name of the table which the tablet is part of. |
| partition_key_start | bytea | Start key of the partition (inclusive). |
| partition_key_end | bytea | End key of the partition (exclusive). |
| state | text | State of the tablet. Check the next section for possible values. |
The state column can have the following values:
| State | Description |
|---|---|
| TABLET_DATA_COPYING | The tablet is doing remote bootstrap. |
| TABLET_DATA_READY | Fresh empty tablets or successfully remote bootstrapped tablets. |
| TABLET_DATA_DELETED | The tablet replica has been deleted from this particular node because the tablet has been deleted from the table. |
| TABLET_DATA_TOMBSTONED | The tablet replica has been deleted from this particular node but the tablet itself is still part of the table and might have data on other nodes. |
| TABLET_DATA_SPLIT_COMPLETED | The tablet split has been completed. |
| TABLET_DATA_INIT_STARTED | The tablet has been initialized as a subtablet of another tablet undergoing a split. |
