> Support query evaluation tracing and how-provenance

> Key: MRQL-93
> URL: https://issues.apache.org/jira/browse/MRQL-93
> Project: MRQL
> Issue Type: New Feature
> Components: Evaluation, Query Translation
> Affects Versions: 0.9.8
> Reporter: Leonidas Fegaras
> Assignee: Leonidas Fegaras
> Priority: Critical
>
> With this new feature, one can trace any piece of a query result to the input
> data that contributed to the result as well as the detailed operations used
> to derive the result. This is called why- and how-provenance in data
> analysis. A traced query will be lifted so that its output will contain the
> provenance information. There will be a GUI (based on JTree) to lazily
> navigate through the provenance data.
