More NOSQL Erlang database options including Riak CouchDB Mnesia. Redis still looks best!!

This is a good resourcebelow  for this comparison:

CouchDB: Best used: For accumulating, occasionally changing data, on which pre-defined queries are to be run. Places where versioning is important.

No good for me

Couchbase looks interesting:

Best used: Any application where low-latency data access, high concurrency support and high availability is a requirement.

For example: Low-latency use-cases like ad targeting or highly-concurrent web apps like online gaming (e.g. Zynga). (200k/second works!) I know some homegrown in memory versions are up 750K/second

Aerospike has no stats here but still waiting from the vendor.

Kyoto Tycoon used for stocks analysis

I do also see Redis is used for: To store real-time stock prices. Real-time analytics. <– This does appear to still be the winner as explained in my video

NOTE: The graph database options may be good for machine learning as in Neo4J. I do think the Goldman Sachs SecDb is built around this technology

About caustic

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at youtube.com/quantlabs
