Subject Another Interesting Question on SPARK SQL
Date Thu, 17 Nov 2016 09:28:30 GMT
Which parts in the diagram above are executed by DataSource connectors and
which parts are executed by Tungsten? or to put it in another way which
phase in the diagram above does Tungsten leverages the Datasource
connectors (such as say cassandra connector ) ?

My understanding so far is that connectors come in during Physical planning
phase but I am not sure if the connectors take logical plan as an input?
