create glue connection to mysql using boto3

Question

I'm trying to create a new aws glue connection. I'm using the boto3 script below. I'm able to connect with similar scripts and retrieve the structure of tables in data catalog databases. So I know the client is working. I know the availability zone is us-west-2 also. I copied the rest of the info from a glue connection I'd already created. I was just trying to test the boto3 script to see if I could create a connection through the script. Does anyone see what the issue might be? I'm trying to connect to a mysql database on an ec2 instance.

code:

# create new connection

response = client.create_connection(
    ConnectionInput={
        'Name': 'tst_scrpt',
        'ConnectionType': 'JDBC',
        'MatchCriteria': [
            'string',
        ],
        'ConnectionProperties': {
            'string': 'jdbc:mysql://xxxxx:3306/disxxx',
            'username':'root',
            'password':'ipxxxxx'
        },
        'PhysicalConnectionRequirements': {
            'SubnetId': 'subnet-04xxxxx',
            'SecurityGroupIdList': [
                'sg-xxxxx'
            ],
            'AvailabilityZone': 'us-west-2'
        }
    }
)

error:

Answer 1

The create_connection Glue API defined by Boto3 does not mention what parameters are to be passed for the 'ConnectionProperties' field. It only mentions key-value pairs are to be supplied.The values to be passed are as below.

client = boto3.client('glue', region_name='<region-to-use>')

response = client.create_connection(
    CatalogId='<account-id>',
    ConnectionInput={
        'Name': '<name-of-the-connection>',
        'Description': 'Test connection',
        'ConnectionType':'JDBC',
        'ConnectionProperties': {
            'USERNAME': '<db-username>',
            'JDBC_ENFORCE_SSL': 'false',
            'PASSWORD': '<db-password>',
            'JDBC_CONNECTION_URL': 'jdbc:protocol://host:port/db_name'
        },
        
        'PhysicalConnectionRequirements': {
            'SubnetId': '<subnet-to-use>', 
            'AvailabilityZone': '<availability-zone-to-use>', 
            'SecurityGroupIdList': ['<security-group(s)-to-use>']
    }
    }
)

Answer 2

I had the ConnectionProperties wrong. replace 'string' with 'JDBC_CONNECTION_URL'. The correction is below.

 'ConnectionProperties': {
                'JDBC_CONNECTION_URL': 'jdbc:mysql://dataxxx:3306/disxxx',
                'username':'root',
                'password':'ip1k5PNCxxxxx'
            }
