Riak Riak is a distributed NoSQL key-value store. Simple operations •  Get •  Put •  Delete 

Key-Value Data Model •  Keys are grouped into buckets. •  All data (objects) are referenced by keys •  Object is composed of metadata and value Object/key Operations KEY VALUE KEY VALUE KEY VALUE bucket 

Masterless & Highly Available Any node can serve client requests Fallbacks are used when nodes are down Always accepts read and write requests Per-request quorums 

Consistent Hashing & The Ring •  160-bit integer keyspace •  Divided into fixed number of evenly-sized partitions •  Partitions are claimed by nodes in the cluster •  Replicas go to the N partitions following the key 32 partitions N=3 node 0 node 1 node 2 node 3 hash(“product/iphone”) 2160/4 2160/2 0 

Failure Scenario •  Node fails •  Requests go to fallback nodes hash(“product/iphone”) node 0 node 1 node 2 node 3 X X X X X X X X 

Hinted Handoff •  Node comes back •  “Handoff” - data returns to recovered node •  Normal operations resume hash(“product/iphone”) node 0 node 1 node 2 node 3 

Riak’s core capability Scalable Add commodity hardware to get more [throughput | processing | storage] 

Riak’s core capability Fault Tolerant All nodes participate equally (no SPOF) All data is replicated (n=3 by default) Cluster transparently survives node failure & network partition 

Tunable Consistency •  n_val - number of replica to store; bucket-level setting. Defaults to “3”. •  w - number of replicas required for a successful write; Defaults to “2”. •  r - number of replica acks required for a successful read. request-level setting. Defaults to “2”. •  pr, pw & dw • Tweak consistency vs. availability 

Two APIs HTTP (just like the web) Protocol Bu"ers (thank you, Google) Client Libraries Ruby, Node.js, Java, Python, Perl, Erlang, PHP, C, Scala, Haskell, Lisp,.NET, Play, and more (supported by either Basho or the community). 

Riak Backend • Riak has a pluggable backend architecture • Bitcask, LevelDB are used the most in production depending on use-case • All writes are appends to a file • This provides crash safety and fast writes 

Accessing Data in Riak Retrieving Single Objects •  Support for retrieving the object associated with a particular bucket / key •  Support for retrieving all of the keys associated with a particular bucket Object/Key Operations Collecting, Parsing, and Storing Data •  Distributed, full-text search engine with an easy-to-use query language, a Solr-like HTTP interface and a Apache Lucene-style query syntax •  Support for a wide variety of mime types, including JSON, plain text, XML and Erlang) •  Ideal for indexing JSON documents, as indexes are built automatically from a schema. Riak Search Seeking Reverse Lookups on Data Stored •  Provides the ability, at write time, to tag an object stored in Riak with one or more values (key/value metadata), which can then be queried •  Useful for finding data that is based on terms other than an objects’ bucket/key pair, or for adding metadata values to a binary object or opaque blob Secondary Indexes (Riak 2i) Processing a Large Dataset •  Provides the general ability to analyze and aggregate data in phases with data locality •  Features Javascript support and Erlang for performance benefit MapReduce Riak Search and 2I Query Results Can be Used as an Input to MapReduce

What Riak is good for ?

What Riak Isn’t •  NOT Relational •  No fixed schema •  NOT Right for Every Project •  Large Objects (Riak CS is a good fit here) •  Dynamic Queries(SQL) 

Modeling Applications in Riak 

Ideal Riak Scenarios •  When you have enough data to require >1 physical machine (preferably > 4) •  When availability is the top requirement •  When your data can be modeled as keys and values When to Use Popular Use Cases •  Ad Networks •  Digital Media •  On-Line Games •  Social Networks •  Social Analysis •  Cloud Operators •  Messaging Services •  Product Catalogs •  Document Management •  Health Care Information Management 

Riak Production Users- growing & growing …. Mobile, Retail & Social Cloud Computing & Advertising Security and Others Gaming, Payments and Others 

Web / Mobile App Growth Case Study for Top Rated Apple App Store App •  #4 most popular Apple App Store Social Networking App at EOY behind Facebook, Skype and Twitter •  Truly Viral Growth: Scaled 10x between Thanksgiving and New Years Day •  Required scaling across multiple IaaS / hosting providers •  Surpassed one billion operations per day 

Mobile-to-Mobile Content Store Bump – Low Latency and Always Available •  800 million pieces of structural data in Riak, including Photos, Chats, and Contact Cards. •  10 million active users •  77 million downloads to date •  Switched to Riak in August 2011 •  #7 Most Downloaded iPhone App 

Enstratus •  It is a cloud infrastructure management solution for deploying and managing enterprise-class applications •  Moved from MySQL to Riak. Reasons- •  Write Scalability •  Resilience to failure across multiple datacenters •  Stores machine and state information, and data supporting analytics and audit control. •  George Reese gave an excellent talk during Ricon last year, link below http://vimeo.com/54887751 “As I’ve looked at a number of problem domains from customers and our own systems, you see this pattern where a relational database has been used just because it’s the default… and the reality is that more of the world is eventually consistent than not”, said George Reese, CTO of enStratus 

Riak MDC- (EDS) Cloud Mobile Social Data Center #2 Data Center #3 Data Center #1 Multi-Data Center Replication Applications, Users and Machines Generate Data 1 2 Riak Stores and Manages Data Efficiently and Effectively •  Clusters are local to regional users to solve latency •  Replication is uni-directional, remote clusters can be setup to replicate data back to a primary cluster, thus synchronizing bi-directionally. •  Easily deploy in many regional zones •  Write everywhere solution •  Easy to scale, can easily add additional data centers

Backups •  Bitcask and LevelDB are both Log-structure stores; cp, rsync, tar, custom backup tools will work •  FS-level snapshots of directory can be done while node is running •  Backups aren't yet perfected and that future releases will have more efficient, specialized backup methods for each backend 

Stats and Monitoring (1) • Riak exposes data about current operating status (counters, histograms, etc.) via the HTTP /stats endpoint or ‘riak- admin status’ • Anything that speaks HTTP can be plugged into Riak • Plugins exist for most OSS monitoring tools (munin, cacti, nagios, graphite, statsd) 

Stats and Monitoring (2) •  ‘riaknostic’ is a suite of diagnostic checks that can used to debug your cluster before it’s in production; checks for common misconfigurations •  Riak Control is a full-fledged management GUI that Basho develops and maintains. 

Riak 1.3 – GA Now •  Active Anti Entropy •  Replication enhancements for MDC •  IPv6 support •  New Look for Riak Control 

What is Riak CS? Key features: •  Multi-Tenant support •  User Authentication and Authorization •  Amazon S3 API-compatibility •  Per-Tenant visibility •  Provisioning, Metering, Billing and Reporting •  Multi part upload up to 5TB 

Riak CS in Action 

Reporting Large Objects AuthZ Riak CS Use Cases Storage for Cloud Computing S3 Without AWS Cloud Drive (General Content Storage) Backup-as-a- Service Archival and Preservation Integration with Workflow Multi-Tenancy 

Multi-Datacenter Replication •  Multi-site storage replication •  Data locality •  Availability in disaster scenarios •  Active backup 

Multi-Datacenter Replication •  Global information for users, buckets and manifests is streamed in real- time •  Objects are replicated in full or real- time sync mode •  If a client requests an object from a site but not all of the blocks that constitute that object have been replicated to that site, missing blocks will be requested and streamed from the “origin” cluster How It Works 

Riak CS Roadmap •  Swift API •  Keystone Integration •  S3 Features •  COPY Object •  Object Versioning •  Cloud Stack Integration 

Riak 1.4 (Roadmap) •  Dynamic Ring Sizing •  2i Pagination •  Performance and Scaling Improvements
