Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation
adb:DescribeTableStatistics	get	DBCluster acs:adb:{#regionId}:{#accountId}:dbcluster/{#DBClusterId}	none	none

Request parameters

Parameter	Type	Required	Description	Example
DBClusterId	string	Yes	The cluster ID. Note You can call the DescribeDBClusters operation to query a list of cluster IDs.	am-****************
PageSize	integer	No	The number of entries per page. Valid values: 30 (default) 50 100	30
PageNumber	integer	No	The page number. Pages start from page 1. Default value: 1.	1
Order	string	No	The order in which to sort the queried information. Specify this parameter as an ordered JSON array that consists of the `Field` and `Type` fields. Example: `[{ "Field":"TableName", "Type":"Asc" }]`. `Field` specifies the field that is used to sort the queried information. The following fields are supported: `TableName`, ColdDataSize, DataSize, PrimaryKeyIndexSize, RowCount, IndexSize, SchemaName, and PartitionCount. `Type` specifies the sorting order. Valid values (case-insensitive): Desc: descending order. Asc: ascending order.	[ { "Field":"TableName", "Type":"Asc" } ]
RegionId	string	No	The region ID of the cluster. Note You can call the DescribeRegions operation to query the most recent region list.	cn-beijing
Keyword	string	No	The keyword that is used to query information by table name.	you_table_name

Response parameters

Parameter	Type	Description	Example
	object	The response parameters.
TotalCount	string	The total number of entries returned.	1
PageSize	string	The number of entries per page.	30
RequestId	string	The request ID.	4C4433FF-5D3A-4C3E-A19C-6D93B2******
PageNumber	string	The page number.	1
DBClusterId	string	The cluster ID.	am-****************
Items	array<object>	The queried table statistics.
	object
SchemaName	string	The name of the database.	test_schema
TableName	string	The name of the table.	test_table
RowCount	long	The number of rows in the table.	3
DataSize	long	The data size of table records. Unit: bytes. Note The data size of table records, excluding the data size of regular index and primary key indexes.	15592
IndexSize	long	The data size of regular indexes. Unit: bytes.	3076
PrimaryKeyIndexSize	long	The data size of primary key indexes. Unit: bytes.	16340
PartitionCount	long	The number of partitions.	1
ColdDataSize	long	The cold data size. Unit: bytes. Note The parameter is returned only for AnalyticDB for MySQL clusters of V3.1.3.4 or later.	0
SpaceRatio	double	The percentage of the table size. Unit: %. Note Formula: Table storage percentage = Total data size of a table/Total data size of the cluster × 100%.	66.23
TotalSize	long	The total data size. Unit: bytes. Note The following formulas can be used to calculate the total data size: Formula 1: Total data size = Hot data size + Cold data size. Formula 2: Total data size = Data size of table records + Data size of regular indexes + Data size of primary key indexes + Data size of other data.	1577
HotDataSize	long	The hot data size. Unit: bytes.	1048576
OtherSize	long	The data size of other data. Unit: bytes.	1048576
