import json
def lambda_handler(event, context):
for record in event.get('events', []):
log_document_db_event(record)
return 'OK'
def log_document_db_event(record):
event_data = record.get('event', {})
operation_type = event_data.get('operationType', 'Unknown')
db = event_data.get('ns', {}).get('db', 'Unknown')
collection = event_data.get('ns', {}).get('coll', 'Unknown')
full_document = event_data.get('fullDocument', {})
print(f"Operation type: {operation_type}")
print(f"db: {db}")
print(f"collection: {collection}")
print("Full document:", json.dumps(full_document, indent=2))
