## Lifecycle configuration
|
|
|
|
When you have multiple rules in an S3 Lifecycle configuration, an object can become eligible for multiple S3 Lifecycle actions. In such cases, Amazon S3 follows these general rules:
|
|
|
|
1. Permanent deletion takes precedence over transition.
|
|
1. Transition takes precedence over creation of delete markers.
|
|
1. When an object is eligible for both a S3 Glacier Flexible Retrieval and S3 Standard-IA (or S3 One Zone-IA) transition, Amazon S3 chooses the S3 Glacier Flexible Retrieval transition.
|
|
|
|
Propagation delay: When you add an S3 Lifecycle configuration to a bucket, there is usually some lag before a new or updated Lifecycle configuration is fully propagated to all the Amazon S3 systems. Expect a delay of a few minutes before the configuration fully takes effect. This delay can also occur when you delete an S3 Lifecycle configuration.
|
|
|
|
Objects can only go down the tiers, not up. Many other constraints apply, like no transition done for objects <128KiB.<br/>
