I’m reaching out to see whether anyone has been solving similar problem as us and could advise on the most efficient approach.
We are developing a dashboard solution using elasticsearch & kibana. We parse results of various static analysis tools (using our custom-built parser), store them in elasticsearch (each issue found in static analysis as a separate document; issues coming from one static analysis run have a same correlationId which links them). Then we have kibana visualizations built over them.
We would like to show list of introduced and fixed issues between static analysis scan A and static analysis scan B.
Does elasticsearch have feature that could be used for that, or do we need to just query the data and do the diff ourselves in a custom component?
Thank you in advance for thoughts and ideas,
Eva
