continue_if_exception

Using ignore_empty_list rather than continue_if_exception

Curator has two general classifications of exceptions: Empty list exceptions, and everything else. The empty list conditions are curator.exception.NoIndices and curator.exception.NoSnapshots. The continue_if_exception option only catches conditions other than empty list conditions. In most cases, you will want to use ignore_empty_list instead of continue_if_exception.

So why are there two kinds of exceptions? When Curator 4 was released, the ability to continue in the event of any exception was covered by the continue_if_exception option. However, an empty list is a benign condition. In fact, it’s expected with brand new clusters, or when new index patterns are added. The decision was made to split the exceptions, and have a new option catch the empty lists.
