Question

以下适用于dynamodb但使用交流发电机失败。

CreateTableRequest createTableRequest = new CreateTableRequest()
        .withTableName("test")
        .withKeySchema(new KeySchemaElement().withAttributeName("id").withKeyType(KeyType.HASH))
        .withKeySchema(new KeySchemaElement().withAttributeName("range").withKeyType(KeyType.RANGE))
        .withAttributeDefinitions(new AttributeDefinition().withAttributeName("id").withAttributeType(ScalarAttributeType.S))
        .withAttributeDefinitions(new AttributeDefinition().withAttributeName("range").withAttributeType(ScalarAttributeType.N))
        .withAttributeDefinitions(new AttributeDefinition().withAttributeName("s1id").withAttributeType(ScalarAttributeType.S))
        .withAttributeDefinitions(new AttributeDefinition().withAttributeName("s1range").withAttributeType(ScalarAttributeType.N))
        .withAttributeDefinitions(new AttributeDefinition().withAttributeName("s2id").withAttributeType(ScalarAttributeType.S))
        .withAttributeDefinitions(new AttributeDefinition().withAttributeName("s2range").withAttributeType(ScalarAttributeType.N))
        .withGlobalSecondaryIndexes(new GlobalSecondaryIndex()
                .withIndexName("s1id-s1range-index")
                .withKeySchema(new KeySchemaElement().withAttributeName("s1id").withKeyType(KeyType.HASH))
                .withKeySchema(new KeySchemaElement().withAttributeName("s1range").withKeyType(KeyType.RANGE))
                .withProjection(new Projection().withProjectionType(ProjectionType.ALL))
                .withProvisionedThroughput(new ProvisionedThroughput().withReadCapacityUnits(10L).withWriteCapacityUnits(10L))
                )
        .withGlobalSecondaryIndexes(new GlobalSecondaryIndex()
                .withIndexName("s2id-s2range-index")

Alternator仅实现DynamoDB的“v1”版本中存在的功能。

支持“dynamodbv2”软件包和方法签名，但只能通过内部映射到Alternator中的“v1”方法。

因此，在Alternator中没有实现更新的功能，如本地或全局二级索引，除非有人采取措施创建适合本地测试的实现，否则可能无法实现。

自创建交流发电机以来，亚马逊已推出“DynamoDB Local for Desktop Development”。 DynamoDB较新功能的用户应考虑使用该工具。（我没有使用此亚马逊工具的经验，因为我们当前的项目仅使用DynamoDB的原始哈希/范围索引功能。）
