He's talking about Apache Spark.
While it can handle 100 MB easily there probably are faster ways to handle that small amount of data. But yes, Spark can handle many PB and doesn't require a ton of changes in the code as you scale up from say 10 TB to 100 PB. The underlying cluster would change, and the performance profile would change a lot (10 TB can be done in-memory ... many PB, not so much)
