Avoid sleeping after first execution

[aulisse]

Hello, a quick question: is it possible to make dynamic-dynamodb stop after the first execution? In other words, is there any configuration, or anything that I can do, to make the python process stop after the first loop on the tables matching the table section?

I am not running the script through a daemon.

Thanks!

It is currently not supported. But I am about to release a new version of dynamic-dynamodb. I will include a command line option (--run-once) that will trigger that behaviour.

1.13.0 is out now, including this change!

Thanks! Perfectly working!

I need the "--run-once" option because I run the script in a Java application running in an autoscaling group that has ~8 EC2 instances, and I don't want that it runs on each server, but exactly on one, by specifying a cron expression.

I exploit the optimistic locking of Dynamo DB, combined with ntp synchronization and a cron expression, in order to run the script exactly on one random active node from inside a java job. Thus, I don't have any single point of failure.
