Future of OR Mapping in Big Data ?

[Awais Bajwa]

Hey Vlad, Can you please throw some light on the future of OR mapping in the big data platform, will it die? or still we can have some Big Data Mapping to some standard structures for different formats?

BigData is OLAP, while OLTP is what ORM tools are targeting now.
Not only the amount of data increases, but database engines become more powerful too.
When Non-volatile memory is going to get cheaper, relation databases will become even faster.

It's worth noting that StackOverflow uses just 2 SQL Server clusters and they really have a lot of data to serve.
