Rerun from Index
The rerun from index utilizes the actual uses the data in the form of Squirro Items which , as they are stored found in the storage layer Elasticsearch index of your Squirro instanceproject.
This rerun mode is always used when you rerun a single pipeline step, but it is also offered as an option when you want to rerun the whole pipeline workflow.
This mode is always available. However, it is not considered as stable as the other mode, and when the workflow includes a non-idempotent step the resulting Squirro Item will not be the same as the first time that it got ingested, even if the workflow has not changed. As an example, consider a Pipelet which modifies the title of an item by appending an exclamation mark. If we invoke the rerun functionality of a workflow on this item n times, the resulting Squirro Item will contain n exclamation marks in its title.
