Apache Spark for Interactive Requests?

Hi,

I am new to Spark and I would like to ask a question on the use case I am trying to work upon.

Plan is to use Hadoop/Spark as a reporting solution, fetching data from an RDBMS(Oracle) source system, perform ETL and execute report jobs using Spark SQL.

The question is, can Spark be used for interactive report requests as well? For example a user requesting a report from a web application.

Will the new Spark Structured Streaming be helpful to my case?

Or should i get the ETL Output into a structured DB for interactive reports?

Please suggest. Thanks in Advance.
