Subject [jira] [Commented] (FALCON-288) Persist lineage information into a persistent store
Date Wed, 05 Feb 2014 07:36:09 GMT

    [ https://issues.apache.org/jira/browse/FALCON-288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13891885#comment-13891885

Venkatesh Seetharam commented on FALCON-288:

We need to discuss 2 things:

* persistent store - rdbms vs a graph db
* object model based on the store we choose

I tried to model in both and the queries for getting a graph for a single execution with multiple
instances for an input involved several inner joins. However, its quite straightforward in

Currently, I have each entity as a vertex with name and type as indexed properties. Each instance
for a given entity is also a vertex with edges to the entity and the instances it uses or
generates with name as the indexed property along with user and timestamp.

is hierarchical.
