Obtains a list of partitions in a metatable.
Operation description
You can call this operation to query only the partitions of a metatable in a MaxCompute or E-MapReduce (EMR) compute engine. If you query partitions of a metatable in an EMR compute engine, only DataLake clusters that use Data Lake Formation (DLF) to manage metadata and Hadoop clusters whose cluster version is earlier than 3.41.0 or 5.7.0 are supported.

Request parameters
Parameter | Type | Required | Description | Example |
---|---|---|---|---|
PageNumber | integer | No | The page number. | 1 |
PageSize | integer | No | The number of entries per page. Default value: 10. Maximum value: 100. | 10 |
TableGuid | string | Yes | The unique identifier of the metatable. | odps.engine_name.table_name |
ClusterId | string | No | The ID of the EMR cluster. This parameter is required only if you set the DataSourceType parameter to emr. You can log on to the EMR console to obtain the ID. | abc |
DatabaseName | string | No | The name of the database. This parameter is required only if you set the DataSourceType parameter to emr. You can call the ListMetaDB operation to query the name of the metadatabase. | abc |
TableName | string | No | The name of the metatable in the EMR cluster. This parameter is required only if you set the DataSourceType parameter to emr. You can call the GetMetaDBTableList operation to query the name of the metatable. | abc |
DataSourceType | string | No | The type of the data source. Valid values: odps and emr. | emr |
SortCriterion | object | No | The logic for sorting partitions in the metatable. | |
SortField | string | No | The field that is used to sort partitions in the metatable. Valid values: name and modify_time. By default, partitions in the metatable are sorted based on their creation time. | name |
Order | string | No | The order in which partitions in the metatable are sorted. Valid values: asc and desc. Default value: desc. | desc |
