The Future of Hadoop: What Happened & What's Possible?
Operational SQL-on-Hadoop
“Transactions were something that were long thought to be out of scope for this style of platform. There are a
lot of important cases for transactions. You are selling a ticket to something then you need to move money from
one place to another. You need to assign a seat to someone. And you need to make sure that the money is in
one place or the other. Not in both, not nowhere. And you need to at the same time assign that seat or not
assign that seat. This is an important class of workload that is currently well served but not by the Hadoop
platform. A year ago Google published a paper describing their internal system they have built on their
platform, that is very similar to Hadoop, which does this, demonstrating that its possible to bring online
transaction processing to this style of platform. And in the past when we have seen its possible, within a few
years it happens. So I think the prediction we can make here is that it is inevitable that we will see just about
every kind of workload be moved to this platform – even Online Transaction Processing.
