To create a DynamoDB desk and add gadgets to it utilizing Python 3 from AWS Lambda, you should use the AWS SDK for Python, often known as Boto3. Right here’s a step-by-step information:
- Arrange your AWS setting:
- Set up Boto3 by working
pip set up boto3
in your native improvement setting. - Arrange your AWS credentials and configure your AWS CLI or setting variables. You’ll find detailed directions within the AWS documentation.
- Set up Boto3 by working
- Create a Lambda operate within the AWS Administration Console:
- Go to the AWS Administration Console and navigate to the Lambda service.
- Click on on “Create operate” and comply with the directions to create a brand new Lambda operate.
- Select the specified runtime as Python 3.x.
- Write the Python code to create the DynamoDB desk and add gadgets:
- Within the Lambda operate code editor, enter the next code:
import boto3
def lambda_handler(occasion, context):
# Create a DynamoDB shopper
dynamodb = boto3.shopper('dynamodb')
# Outline the desk title and schema
table_name = 'YourTableName'
table_schema = [
{
'AttributeName': 'ID',
'AttributeType': 'N'
},
{
'AttributeName': 'Name',
'AttributeType': 'S'
}
]
# Create the DynamoDB desk
dynamodb.create_table(
TableName=table_name,
KeySchema=[
{
'AttributeName': 'ID',
'KeyType': 'HASH'
}
],
AttributeDefinitions=table_schema,
ProvisionedThroughput={
'ReadCapacityUnits': 5,
'WriteCapacityUnits': 5
}
)
# Look forward to the desk to be created
dynamodb.get_waiter('table_exists').wait(TableName=table_name)
# Add gadgets to the desk
gadgets = [
{
'ID': {'N': '1'},
'Name': {'S': 'Item 1'}
},
{
'ID': {'N': '2'},
'Name': {'S': 'Item 2'}
}
]
with dynamodb.batch_writer(TableName=table_name) as batch:
for merchandise in gadgets:
batch.put_item(Merchandise=merchandise)
return {
'statusCode': 200,
'physique': 'DynamoDB desk created and gadgets added efficiently.'
}
- Configure the Lambda operate:
- Within the AWS Lambda operate configuration, specify the next:
- Handler: Enter the title of the Python file and the lambda_handler operate. For instance,
filename.lambda_handler
. - Runtime: Python 3.x.
- Timeout: Set an acceptable timeout based mostly on the anticipated execution time of your code.
- Function: Select or create an execution position with acceptable DynamoDB permissions.
- Handler: Enter the title of the Python file and the lambda_handler operate. For instance,
- Within the AWS Lambda operate configuration, specify the next:
- Save and check the Lambda operate:
- Save the Lambda operate by clicking on the “Save” button.
- Take a look at the operate by clicking on the “Take a look at” button and configuring a check occasion.
- Monitor the execution logs and examine for any errors or exceptions.
If you invoke the Lambda operate, it should create a DynamoDB desk with the desired schema and add the gadgets to it utilizing a batch write operation. Be sure that to exchange 'YourTableName'
with the specified title on your DynamoDB desk.
Be sure that the IAM position assigned to the Lambda operate has the mandatory permissions to create and write to DynamoDB tables.
