DatabaseMigrationService.Client.describe_table_statistics(**kwargs)¶Returns table statistics on the database migration task, including table name, rows inserted, rows updated, and rows deleted.
Note that the "last updated" column the DMS console only indicates the time that DMS last updated the table statistics record for a table. It does not indicate the time of the last update to the table.

Request Syntax
response = client.describe_table_statistics(
ReplicationTaskArn='string',
MaxRecords=123,
Marker='string',
Filters=[
{
'Name': 'string',
'Values': [
'string',
]
},
]
)
[REQUIRED]
The Amazon Resource Name (ARN) of the replication task.
The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a pagination token called a marker is included in the response so that the remaining results can be retrieved.
Default: 100
Constraints: Minimum 20, maximum 500.
MaxRecords .Filters applied to table statistics.
Valid filter names: schema-name | table-name | table-state
A combination of filters creates an AND condition where each record matches all specified filters.
Identifies the name and value of a filter object. This filter is used to limit the number and type of DMS objects that are returned for a particular Describe* call or similar operation. Filters are used as an optional parameter for certain API operations.
The name of the filter as specified for a Describe* or similar operation.
The filter value, which can specify one or more values used to narrow the returned results.
