Building a relevance platform with Couchbase and Elasticsearch

Building a relevance platform with Couchbase and Elasticsearch

These slides were from my Goto Amsterdam presentation. During this presentation I went into detail about how we're building a high performance relevance platform at Hippo with Couchbase and Elasticsearch. The talk will also cover why we chose CouchBase for storage and how Elasticsearch can be used for search and analytics. I shared how we integrated and leverage both products full-circle from within our Hippo CMS product.

    How we deliver relevant content @Hippo
  8. follow the Hippo trail OneHippo @ Goto Registration Visitor -

    entity making HTTP requests Collector - records data about a visitor or his behavior Example: location collector (GeoIPCollector) Targeting Data - all data about a specific visitor Example: IP address is located in Amsterdam
  9. follow the Hippo trail OneHippo @ Goto Matching Characteristic -

    a type of fact about visitors Example: "comes from a city", "experiences a type of weather" Target Group - the specification of a Characteristic Example: "comes from a European city", "comes from Amsterdam" Persona - one or more target groups that describe a certain type of visitor Example: "Jim, the European urban consumer", "Alice, the Pet owner"

    Couchbase
  36. follow the Hippo trail OneHippo @ Goto Why Couchbase? •

    Drop-in replacement for memcached • Read/Write-through cache • High throughput • Easy scalability • Schema flexibility • Low latency
  37. follow the Hippo trail OneHippo @ Goto Couchbase • Open

    Source • Document-oriented • Easy Scalable • Consistent High Performance
  38. follow the Hippo trail OneHippo @ Goto Performance • Object

    managed cache • Write Queue to disk • Avoids Cold Cache
  39. follow the Hippo trail OneHippo @ Goto Easy scalable •

    Auto sharding • Cross cluster replication (XDCR) • Master - Master replication
  40. follow the Hippo trail OneHippo @ Goto Flexible data model

    • Native JSON support • Incremental Map Reduce • Gives power to the developer
