Ejemplo 1: En este ejemplo se crea una tabla denominada Thread que tiene una clave principal compuesta por «ForumName» (tipo hash de clave) y «Subject» (rango de tipos de clave). El esquema utilizado para construir la tabla se puede canalizar hacia cada cmdlet tal como se muestra o se especifica con el parámetro -Schema.

$schema = New-DDBTableSchema $schema | Add-DDBKeySchema -KeyName "ForumName" -KeyDataType "S" $schema | Add-DDBKeySchema -KeyName "Subject" -KeyType RANGE -KeyDataType "S" $schema | New-DDBTable -TableName "Thread" -ReadCapacity 10 -WriteCapacity 5

Salida:

AttributeDefinitions : {ForumName, Subject} TableName : Thread KeySchema : {ForumName, Subject} TableStatus : CREATING CreationDateTime : 10/28/2013 4:39:49 PM ProvisionedThroughput : Amazon.DynamoDBv2.Model.ProvisionedThroughputDescription TableSizeBytes : 0 ItemCount : 0 LocalSecondaryIndexes : {}

Ejemplo 2: en este ejemplo se crea una tabla denominada Thread que tiene una clave principal compuesta por «ForumName» (tipo hash de clave) y «Asunto» (rango de tipos de clave). También se define un índice secundario local. La clave del índice secundario local se establecerá automáticamente a partir de la clave hash principal de la tabla (ForumName). El esquema utilizado para construir la tabla se puede canalizar hacia cada cmdlet tal como se muestra o se especifica con el parámetro -Schema.

$schema = New-DDBTableSchema $schema | Add-DDBKeySchema -KeyName "ForumName" -KeyDataType "S" $schema | Add-DDBKeySchema -KeyName "Subject" -KeyDataType "S" $schema | Add-DDBIndexSchema -IndexName "LastPostIndex" -RangeKeyName "LastPostDateTime" -RangeKeyDataType "S" -ProjectionType "keys_only" $schema | New-DDBTable -TableName "Thread" -ReadCapacity 10 -WriteCapacity 5

Salida:

AttributeDefinitions : {ForumName, LastPostDateTime, Subject} TableName : Thread KeySchema : {ForumName, Subject} TableStatus : CREATING CreationDateTime : 10/28/2013 4:39:49 PM ProvisionedThroughput : Amazon.DynamoDBv2.Model.ProvisionedThroughputDescription TableSizeBytes : 0 ItemCount : 0 LocalSecondaryIndexes : {LastPostIndex}

Ejemplo 3: En este ejemplo se muestra cómo utilizar una canalización única para crear una tabla denominada Thread que tenga una clave principal compuesta por «ForumName» (hash de tipo de clave) y «Asunto» (rango de tipos de clave) y un índice secundario local. Los comandos Add- DDBKeySchema y Add- DDBIndexSchema crean un TableSchema objeto nuevo si no lo proporcionan la canalización o el parámetro -Scheme.

New-DDBTableSchema | Add-DDBKeySchema -KeyName "ForumName" -KeyDataType "S" | Add-DDBKeySchema -KeyName "Subject" -KeyDataType "S" | Add-DDBIndexSchema -IndexName "LastPostIndex" ` -RangeKeyName "LastPostDateTime" ` -RangeKeyDataType "S" ` -ProjectionType "keys_only" | New-DDBTable -TableName "Thread" -ReadCapacity 10 -WriteCapacity 5

Salida:

AttributeDefinitions : {ForumName, LastPostDateTime, Subject} TableName : Thread KeySchema : {ForumName, Subject} TableStatus : CREATING CreationDateTime : 10/28/2013 4:39:49 PM ProvisionedThroughput : Amazon.DynamoDBv2.Model.ProvisionedThroughputDescription TableSizeBytes : 0 ItemCount : 0 LocalSecondaryIndexes : {LastPostIndex}
