创建一个DynamoDB的四种方法:
1. 在DynamoDB页面,创建一个
2. 通过cloudformation创建一个
创建的模板 JSON代码如下:
{
"AWSTemplateFormatVersion": "2010-09-09",
"Resources": {
"PetTable": {
"Type": "AWS::DynamoDB::Table",
"Properties": {
"AttributeDefinitions" : [
{
"AttributeName": "pet_species",
"AttributeType": "S"
},
{
"AttributeName": "pet_id",
"AttributeType": "N"
}
],
"KeySchema" : [
{
"AttributeName": "pet_species",
"KeyType": "HASH"
},
{
"AttributeName": "pet_id",
"KeyType": "RANGE"
}
],
"TableName": "PetInventory",
"BillingMode": "PAY_PER_REQUEST"
}
}
}
}
3. 通过awscli
以下命令可以创建:
aws dynamodb\
create-table\
--table-name PetInventory\
--attribute-definitions\
AttributeName=pet_species,AttributeType=S\
AttributeName=pet_id,AttributeType=S\
--key-schema\
AttributeName=pet_species,KeyType=HASH\
AttributeName=pet_id,KeyType=RANGE\
--billing-mode PAY_PER_REQUEST
4. Python创建
脚本如下:
import boto3
ddb = boto3.client('dynamodb')
createResponse = ddb.create_table(
AttributeDefinitions=[
{
'AttributeName':'pet_species',
'AttributeType': 'S',
},
{
'AttributeName':'pet_id',
'AttributeType':'N'
}
],
KeySchema=[
{
'AttributeName':'pet_species',
'KeyType':'HASH'
},
{
'AttributeName':'pet_id',
'KeyType':'RANGE'
},
],
BillingMode = 'PAY_PER_REQUEST',
TableName='PetInventory'
)
