Tablestore:Update the configurations of a table

Prerequisites

• An OTSClient instance is initialized. For more information, see Initialize an OTSClient instance.

• A data table is created. For more information, see Create a data table.

API operation

"""
Update the configurations of a data table by using table_options or reserved_throughput. 
"""
def update_table(self, table_name, table_options, reserved_throughput):

Parameters

For more information, see Parameters.

Examples

# Create a table_options instance. Set the TTL of data in the table to 31,536,000 seconds. If the retention period of data in the table exceeds the TTL value, the data is automatically deleted. Specify that up to five versions of data in each attribute column of the table can be retained and the maximum difference between the current system time and the specified data version when the data is written is one day. 
table_options = TableOptions(31536000, 5, 86400)

try:
    # Call the UpdateTable operation to update the reserved read or write throughput of the table. 
    ots_client.update_table('SampleTable', table_options, None)
    # If no exception is thrown, the update is successful. 
    print("update table succeeded")
except Exception:
    # If an exception is thrown, the update fails. Handle the exception. 
    print("update table failed")

# Set the new reserved read throughput to 1 and the new reserved write throughput to 1. You can set the reserved read and write throughput only to 0 for a data table in a capacity instance. 
reserved_throughput = ReservedThroughput(CapacityUnit(1, 1))

try:
    client.update_table('<TABLE_NAME>', None, reserved_throughput)
    print("update table succeeded.")
except Exception:
    print("update table failed.")
