Subject from relational to bigger data
Date Thu, 19 Dec 2013 20:35:29 GMT
We have a large relational database ( ~ 500 GB, hundreds of tables ).

We have summary tables that we rebuild from scratch each night that takes
about 10 hours.
>From these summary tables, we have a web interface that accesses the
summary tables to build reports.

There is a business reason for doing a complete rebuild of the summary
tables each night, and using
views (as in the sense of Oracle views) is not an option at this time.

If I wanted to leverage Big Data technologies to speed up the summary table
rebuild, what would be the first step into getting all data into some big
data storage technology?

Ideally in the end, we want to retain the summary tables in a relational
database and have reporting work the same without modifications.

It's just the crunching of the data and building these relational summary
tables where we need a significant performance increase.
