Description
With Atlas storing metadata & lineage data , from a governance perspective we would like to ask questons such as
- what different data sources were used to produce this report last year compared to this year?
- how was this salary column in the employee table classified on 6 Apr 2015?
These queries are needed to support audit, and to aid in process improvement + root cause analysis
To do so we need temporal support in atlas. A query should be able to indicate the point in time that it applies to. This means keeping track of times, versions within atlas. Potentially this means not just the nodes in the graph, but the edges too, however this can mean an ever increasing graph which can get out of control.
opening up this JIRA to enable an evaluation/ discussion of what we might be able to do
