Is it possible to synchronously invoke an AWS Lambda function from Python Boto?

Question

This page shows only a method for asynchronous invocation. I imagined there would be a synchronous invocation option.

http://boto.readthedocs.org/en/latest/ref/awslamba.html?highlight=invoke

Apparently it is possible with .NET:

How can I invoke an AWS Lambda function from my EC2 instance?

Answer 1

The documentation says to specify InvocationType as RequestResponse for synchronous invocation

response = client.invoke(
    FunctionName='string',
    InvocationType= 'RequestResponse',
    LogType='None'|'Tail',
    ClientContext='string',
    Payload=b'bytes'|file,
    Qualifier='string'
)

Answer 2

You can certainly do this.

response = client.invoke(
    FunctionName='string',
    InvocationType='Event'|'RequestResponse'|'DryRun',
    LogType='None'|'Tail',
    ClientContext='string',
    Payload=b'bytes',
    Qualifier='string'
)
