# I needed to delete ~300k objects from an S3 bucket in a hurry. The better and cheaper solution is to use a lifecycle rule, but those can take a day or two to take effect.

# 1. List all the objects in the bucket, transform them 1000 at a time into request objects for DeleteObjects, write each to a separate file

You can guarantee session affinity with services, but not as you are describing. So, your customers 1-1000 won't use pod-1, but they will use all the pods (as a service makes a simple load balancing), but each customer, when gets back to hit your service, will be redirected to the same pod.

Note: always within time specified in (default 10800):

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
