NoSQL for the SQL Server Pro

Is NoSQL just Hadoop?

• HUGE Hype factor over last few years

Apache Hadoop is a software framework that supports data-intensive distributed applications under a free license• enables applications to work with thousands of nodes and petabytes of data• was inspired by Google's MapReduce and Google File System (GFS) papers

Hadoop in the Enterprise

Working with HadoopCommon Tools / Languages• Java (JDK) / Eclipse• MapReduce

• Map (query/format)• Reduce (aggregate)• plug-in for Eclipse (Java)

• Pig (ETL -- Java)• Hive (HQL Query)

• HBase tables• Others

• Mahout (analyze)• Karmasphere (analyze)• R (analyze)

Demo -HDInsight– Cluster Allocation

What is the relationship?

NoSQL BigData

BigData = Exponentially More Data• Retail Example -> ‘Feedback Economy’– Number of transactions– Number of behaviors (collected every minute)

12:00 12:30 1:00 1:30 2:00 2:300

500

1000

1500

2000

2500

BigData = ‘Next State’ Questions

• What could happen?• Why didn’t this happen?• When will the next new thing

happen?• What will the next new thing be?• What happens?

Collecting Behavioral

data

Demo - HDInsight - MapReduce

Hitting (Relational) Walls

• CA– Highly-available

consistency• CP– Enforced consistency

• AP– Eventual consistency

So many NoSQL options• More than just the Elephant in the room• Over 120+ types of NoSQL databases

Flavors of NoSQL

Key / Value Database• Schema-less• State (Persistent or Volatile)• Examples– AWS Dynamo DB– Riak

Column Database

• Wide, sparse column sets• Examples:– Cassandra– HBase– BigTable– GAE HR DS– Azure Tables– SQL 2012

Tabular Model

More about Column Databases

• Type A– Column-families– Non-relational– Sparse– Examples: HBase, Cassandra, xVelocity (SQL 2012 Tabular)

• Type B– Column-stores– Relational– Dense– Example:

• SQL Server 2012 Columnstore index

Demo - Document Database (Mongo DB)

• document-oriented (collection of JSON documents) w/semi structured data– Encodings include BSON, JSON, XML…

• binary forms – PDF, Microsoft Office documents --

Word, Excel…)

Demo - Graph Database (Neo4j)• a lot of many-to-many relationships• recursive self-joins • when your primary objective is quickly

finding connections, patterns and relationships between the objects within lots of data

So which type of NoSQL? Back to CAP…

Which type of NoSQL for which type of data?

Type of Data Type of NoSQL solution Example

Log files Wide Column HBase

Product Catalogs Key Value on disk DynamoDB

User profiles Key Value in memory Redis

Startups Document MongoDB

Social media connections Graph Neo4j

LOB w/Transactions NONE! Use RDBMS SQL Server

Cloud-hosted NoSQL up to 50x CHEAPER

The reality…two pivots

Storage Methods• SQL (RDBMS) • NoSQL

Storage Locations• On premises • Cloud-hosted

NoSQL (Cloud) BLOB Storage Buckets• Amazon – S3 or Glacier– The gold standard

• Google – Cloud Storage– Free for developers

• Microsoft Azure BLOBS• DropBox, Box…

Cloud-hosted RDBMS• AWS RDS – SQL Server,

mySQL, Oracle– Medium cost– Solid feature set, i.e. backup,

snapshot– Use existing tooling

• Google – mySQL– Lowest cost– Most limited RDBMS

functionality• Microsoft – SQLAzure

– Highest cost

Demo - AWS RDS

• SQL Server, MySQL or Oracle• Essential to understand pricing models

Cloud Offerings– RDBMS AND NoSQL

Cloud RDBMS RDS – all major mySQL SQL Azure

• Interactive Hadoop?

Other types of cloud data services

Hosting public datasets• Pay to read• Earn revenue by offering for

read

Cleaning / matching (your) data • ETL – Microsoft Data

Explorer, Google Refine• Data Quality – Windows

Azure Data Market, InfoChimps, DataMarket.com

NoSQL To-Do ListUnderstand CAP & types of NoSQL databases• Use NoSQL when business needs designate• Use the right type of NoSQL for your business problem

Try out NoSQL on the cloud• Quick and cheap for behavioral data• Mashup cloud datasets• Good for specialized use cases, i.e. dev, test , training environments

Learn noSQL access technologies• New query languages, i.e. MapReduce, R, Infer.NET • New query tools (vendor-specific) – Google Refine, Amazon

Karmasphere, Microsoft Excel connectors, etc…
