Common MongoDB Use Cases

  1. 1. MongoDB Common Use Cases
  2. 2. Emerging NoSQL Space RDBMS RDBMS RDBMS Data Data Warehou Warehou NoSQL se seThe beginning Last 10 years Today
  3. 3. Qualities of NoSQL WorkloadsFlexible data models High Throughput Large Data Sizes• Lists, Nested Objects • Lots of reads • Aggregate data size• Sparse schemas • Lots of writes • Number of objects• Semi-structured data• Agile DevelopmentLow Latency Cloud Computing Commodity• Both reads and writes • Run anywhere Hardware• Millisecond latency • No assumptions about • Ethernet hardware • Local disks • No / Few Knobs
  4. 4. MongoDB was designed for thisFlexible data models High Throughput Large Data Sizes• Lists, Nested Objects • Lots of reads • Aggregate data size • schemas• SparseJSON based • writes • Lots of Replica Sets to • Number of objects shards • 1000’s of• Semi-structuredmodel object data scale reads in a single DB • Dynamic• Agile Development • Sharding to • Partitioning of schemas scale writes dataLow Latency Cloud Computing Commodity• Both reads and writes • Run anywhere Hardware • In-memory• Millisecond latency • No • Scale-out to assumptions about • Ethernet • Designed for cache overcome hardware • Local disks • No / Few Knobs “typical” OS and • Scale-out hardware local file system working set limitations
  5. 5. Example customersContent Management Operational Intelligence Product Data Management w User Data Management High Volume Data Feeds
  7. 7. High Volume Data Feeds Machine • More machines, more sensors, more Generated data Data • Variably structuredStock Market • High frequency trading DataSocial Media • Multiple sources of data Firehose • Each changes their format constantly
  8. 8. High Volume Data Feed Flexible document model can adapt to changes in sensor format Asynchronous writes Data DataSources Data Sources Data Write to memory with Sources periodic disk flush Sources Scale writes over multiple shards
  9. 9. Operational Intelligence • Large volume of state about usersAd Targeting • Very strict latency requirements • Expose report data to millions of customers Real time • Report on large volumes of datadashboards • Reports that update in real timeSocial Media • What are people talking about? Monitoring
  10. 10. Operational Intelligence Parallelize queries Low latency reads across replicas and shards API In database aggregationDashboards Flexible schema adapts to changing input dataCan use same clusterto collect, store, and report on data
  11. 11. Behavioral Profiles Rich profiles collecting multiple complex actions1 See Ad Scale out to support { cookie_id: “1234512413243”, high throughput of advertiser:{ apple: { activities tracked actions: [2 See Ad { impression: ‘ad1’, time: 123 }, { impression: ‘ad2’, time: 232 }, { click: ‘ad2’, time: 235 }, { add_to_cart: ‘laptop’, sku: ‘asdf23f’, time: 254 }, Click { purchase: ‘laptop’, time: 354 }3 ] } } } Dynamic schemas make it easy to track Indexing and4 Convert vendor specific querying to support attributes matching, frequency capping
  12. 12. Product Data ManagementE-Commerce • Diverse product portfolio Product • Complex querying and filtering Catalog • Scale for short bursts of high- volume trafficFlash Sales • Scalable but consistent view of inventory
  13. 13. Content Management • Comments and user generated News Site content • Personalization of content, layoutMulti-Device • Generate layout on the fly for each rendering device that connects • No need to cache static pages • Store large objects Sharing • Simple modeling of metadata
  14. 14. Content Management Geo spatial indexing Flexible data model for location basedGridFS for large for similar, but searches object storage different objects { camera: “Nikon d4”, location: [ -122.418333, 37.775 ] } { camera: “Canon 5d mkII”, people: [ “Jim”, “Carol” ], taken_on: ISODate("2012-03-07T18:32:35.002Z") } { origin: “facebook.com/photos/xwdf23fsdf”, license: “Creative Commons CC0”, size: { dimensions: [ 124, 52 ], units: “pixels” Horizontal scalability } for large data sets }
  15. 15. User Data Management Video • User state and session Games management Social • Scale out to large graphs Graphs • Easy to search and process Identity • Authentication, Authorization,Management and Accounting
  16. 16. Social Graphs Native support forArrays makes it easyto store connections inside user profile Sharding partitions user profiles across Documents enable Social Graph available servers disk locality of all profile data for a user
  18. 18. Good fits for MongoDBApplication Characteristic Why MongoDB might be a good fitVariable data in objects Dynamic schema and JSON data model enable flexible data storage without sparse tables or complex joinsLow Latency Access Memory Mapped storage engine caches documents in RAM, enabling in-memory performance. Data locality of documents can significantly improve latency over join based approachesHigh write or read throughput Sharding + Replication lets you scale read and write traffic across multiple serversLarge number of objects to Sharding lets you split objects across multiplestore serversCloud based deployment Sharding and replication let you work around hardware limitations in clouds.
