This question already has an answer here:
I tried to post the question below on Stack Overflow, then on Cross Validated, then on Server Fault but my question has been stated as off-topic each time. I'm a bit fed up because I have posted far more answers than questions on Stack Overflow and the day I need some help: no way. I always asked how could I make this question not off-topic or where would it be better to post then, but no answer. Just a downvote or on-hold response. I know it is not a programming issue but there are many very, very similar questions on Stack Overflow so I am really surprised. It seems a bit more picky when it relates to questions on R.
R web-service for real-time prediction with online learning
What free framework or R packages should I use to deploy R as a web service handling many models for real-time prediction (with online learning) ?
It should be able to address those key points:
- allow parallel processing/requests while handling a memory/cpu policy preventing reaching memory/cpu limits.
- update many models in parallel safely (ie. prevent concurrent updates). able to quickly load/unload many models on a single machine because not all models (ie. >1000) could fit in memory.
- handle large streams with low footprint (out-of-core).
- able to use VowpalWabbit and StreamMOA R packages.
- web service could be Http or Thrift based.
Thanks a lot for any help!
