Common MongoDB Use Cases

  1. 1. Software Engineer, MongoDB Hannes Magnusson #MongoDB Common MongoDB Use Cases
  2. 2. NoSQL and MongoDB
  3. 3. NoSQL Features Flexible Data Models • Lists, embedded objects • Sparse data • Semi-structured data • Agile development High Data Throughput • Reads • Writes Big Data • Aggregate Data Size • Number of Objects Low Latency • For reads and writes • Millisecond Latency Cloud Computing • Runs everywhere • No special hardware Commodity Hardware • Ethernet • Local data storage • JSON Based • Dynamic Schemas • Replica Sets to scale reads • Sharding to scale writes • 1000s of shards in a single DB • Data partitioning • Designed for “typical” OS and local file system • Scale-out to overcome hardware limitations • In-memory cache • Scale-out working set
  4. 4. Use Cases
  5. 5. High Volume Data Feeds • More machine forms, sensors & data • Variably structured Machine Generated Data • High frequency trading • Daily closing priceSecurities Data • Multiple data sources • Each changes their format consistently • Student Scores, ISP logs Social Media / General Public
  6. 6. High Volume Data Feeds Data Sources Asynchronous Writes Flexible document model can adapt to changes in sensor format Write to memory with periodic disk flush Data Sources Data Sources Data Sources Scale writes over multiple shards
  7. 7. Operational Intelligence • Large volume of users • Very strict latency requirements • Sentiment Analysis Ad Targeting • Expose data to millions of customers • Reports on large volumes of data • Reports that update in real time Real time dashboards • Join the conversation • Catered Games • Customized Surveys Social Media Monitoring
  8. 8. Operational Intelligence Dashboards API Low latency reads Parallelize queries across replicas and shards In database aggregation Flexible schema adapts to changing input data Can use same cluster to collect, store and report on data

  10. 10. Metadata • Diverse product portfolio • Complex querying and filtering • Multi-faceted product attributes Product Catalogue • Data mining • Call records • Insurance Claims Data analysis • Retina Scans • FingerprintsBiometric
  11. 11. Metadata { ISBN: ‚00e8da9b‛, type: ‚Book‛, country: ‚Egypt‛, title: ‚Ancient Egypt‛ } { type: ‚Artifact‛, medium: ‚Ceramic‛, country: ‚Egypt‛, year: ‚3000 BC‛ } Flexible data model for similar but different objects Indexing and rich query API for easy searching and sorting db.archives. find({ ‚country”: ‚Egypt‛ }); db.archives. find({key:‚type”, value:‚Artifact‛}); Indexing techniques that fit your data modeling
  12. 12. Content Management • Comments and user generated content • Personalization of content and layout News Site • Generate layout on the fly • No need to cache static pages Multi-device rendering • Store large objects • Simpler modeling of metadataSharing
  13. 13. Content Management { 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: ‚‛, license: ‚Creative Commons CC0‛, size: { dimensions: [ 124, 52 ], units: ‚pixels‛ } } Flexible data model for similar but different objects Horizontal scalability for large data sets Geo spatial indexing for location-based searches GridFS for large object storage
  14. 14. Is MongoDB a good fit for my use case? Is there an Ideal use case?
  15. 15. Application Why MongoDB Might be a good fit Large number of objects to store Sharding lets you split objects across multiple servers High write / read throughput and data distribution Sharding + Replication lets you scale read and write traffic across multiple servers, multiple tenants, or data centers Low latency access Memory mapped storage engine caches documents in RAM, enabling in-memory operations. Data locality of documents significantly improves latency over join- based approaches Variable data in objects Dynamic schema and JSON data model enable flexible data storage without sparse tables or complex joins, and provide for an intuitive query language Cloud based deployment Sharding and replication let you work around hardware limitations in the cloud.
