Contoh 1: Untuk memodifikasi mode penagihan tabel
update-table
Contoh berikut meningkatkan kapasitas baca dan tulis yang disediakan di atas meja.MusicCollection
aws dynamodb update-table \ --table-name
MusicCollection
\ --billing-modePROVISIONED
\ --provisioned-throughputReadCapacityUnits=15,WriteCapacityUnits=10
Output:
{ "TableDescription": { "AttributeDefinitions": [ { "AttributeName": "AlbumTitle", "AttributeType": "S" }, { "AttributeName": "Artist", "AttributeType": "S" }, { "AttributeName": "SongTitle", "AttributeType": "S" } ], "TableName": "MusicCollection", "KeySchema": [ { "AttributeName": "Artist", "KeyType": "HASH" }, { "AttributeName": "SongTitle", "KeyType": "RANGE" } ], "TableStatus": "UPDATING", "CreationDateTime": "2020-05-26T15:59:49.473000-07:00", "ProvisionedThroughput": { "LastIncreaseDateTime": "2020-07-28T13:18:18.921000-07:00", "NumberOfDecreasesToday": 0, "ReadCapacityUnits": 15, "WriteCapacityUnits": 10 }, "TableSizeBytes": 182, "ItemCount": 2, "TableArn": "arn:aws:dynamodb:us-west-2:123456789012:table/MusicCollection", "TableId": "abcd0123-01ab-23cd-0123-abcdef123456", "BillingModeSummary": { "BillingMode": "PROVISIONED", "LastUpdateToPayPerRequestDateTime": "2020-07-28T13:14:48.366000-07:00" } } }
