Big Data and APIs

Big Data: more users, more interactions, more data science

Many complex data science problems, such as sparse matrix factorizations have very concrete applications today. These algorithms constitute  the fundation of machine learning engines which help us - the users - to filter, categorize and tag information.Two approaches can be taken in order to process the data: by analysing  large chunks of data (mostly translates into batch, lenghty operations) or per-request event-driven processing (mostly translates into responsive, reactive API and streaming computing in realtime). 

These two approaches can be combined in a unified architecture where large inferences and broad analysis are performed in batch mode on a Hadoop Yarn framework, while faster, reactive analytics can be performed by a actor and event based distributed comupting in Akka.

Those two run-time frameworks have very different latency, throughput, data and compute caracteristsics. No/New SQL distributed database technologies can be successfully used to bridge those two run-time frameworks.
