Beyond the Scope of one tool

Beyond the Scope of one file system

Beyond the Scope of

Analyzing

What kind of questions do you need to ask?

Basho Confidential 31

32

Error Analysis?As simple as NoSQL + Solr

33

Patterns? Machine Learning?

Multi-client writes to NoSQL & HDFS

OR

35

NoSQL + ETL process => other datastore + Spark

and/or Hadoop M/R

OR

NoSQL & Apache Storm to Kafka to HDFS

So we agree. NoSQL is helpful.

Side Note: NoSQL is a terrible term

In Review

You can’t analyze what you don’t have.

And you don’t want an analysis system to be unreliable.

•  Hadoop A framework that allows for the distributed processing of large data sets across clusters

•  SparkA fast, general engine for large-scale data processing

•  Storm A distributed real-time computation system

•  NoSQLA collection of highly scalable, highly available systems that fall within CAP theorem

•  SolrApache project for indexing text for search

•  KafkaDistributed scalable pub/sub messaging queue
