Is there something about the GCS trigger that doesn't work for you? I hear you on Python 3, but I'm also curious about "serious control over the environment". Can you be more specific?
Here are our main issues with Lambda, from highest-to-lowest priority: - It supports Python 2.7 only. We need Python 3.4+ support. - We can't increase CPU allocation without increasing RAM allocation, making them far more expensive than we need. - Using psycopg2 on it is a PITA due to their handling of system dependencies. - The system is entirely proprietary, making it impossible to run it locally for testing. - Clo…
