BarCamp cloudsearch
- 1. Amazon CloudSearch Chris Moyer VP of Technology @ Newstex, LLC
- 2. Who am I? ✦ Author ✦ Building Applications in the Cloud ✦ Not just about AWS, but cloud computing “patterns” in general
- 3. Author ✦ Now available in multiple languages ✦ Available through Amazon.com (and in Kindle format), and BarnesAndNobel
- 4. Newstex VP ✦ VP of Technology: Newstex, LLC ✦ Took Newstex from a datacenter to AWS ✦ All applications run entirely within AWS
- 5. Indexing with DynamoDB! ✦ DynamoDB is a NoSQL Engine ✦ Not Indexed
- 6. Oh wait... Officially Released Thursday (4/11)
- 7. Reverse...
- 8. Introducing CloudSearch ✦ Powered by “a9” search engine ✦ Same search used by Amazon.com ✦ Similar to Apache Solr ✦ Managed Service, Auto scale based on usage and storage ✦ Searches full-text and metadata ✦ Customized Schema
- 9. What is CloudSearch? ✦ Search Domains ✦ Full text indexing of documents and Metadata ✦ Simple Document API ✦ Rich API to search - no AWS Credentials required ✦ “Search Facets” ✦ “Result Field”
- 10. Search Domains ✦ Single set of Endpoints ✦ Completely Isolated ✦ Can not search across domains ✦ Set of instances ✦ Set of permissions ✦ Specific Schema
- 11. Indexing ✦ Key -> value (multi) ✦ Specify schema!: Limit of 100 values per item ✦ Supports different types: ✦ text (default) ✦ uint ✦ literal (tokenized) ✦ Options on each index: ✦ Search ✦ Facet Can’t use both! ✦ Result
- 12. Advanced Indexing Settings ✦ Rank expressions: how to determine match results ✦ Stopwords - Words to remove and not index: “the”, “a” “an” “and” ✦ Stemming: Reduce a given word to its “root form”: “Learning”: “learn” ✦ Synonyms: Transform one word into another “google”: “search”
- 13. Document API ✦ REST-Style API ✦ Not signed requests ✦ Permissions by IP ✦ Can also upload via the Console ✦ Add via SDF (Search Document Format) ✦ Batch operations, add and delete ✦ Each document has an ID and a Version
- 14. Search API ✦ Authorized by IP address (or CIDR range) ✦ Supports “simple” and “boolean” query searches ✦ Search across all indexed fields, or specific fields, or both ✦ Returns simple JSON or XML output ✦ Also allows returning of Facets.
- 15. Search Facets ✦ Special “filtering” fields for fields that do not have a lot of unique values ✦ Each search request can return these counts ✦ Can be used to limit further searches by adding a boolean query ✦ Can not also be returned in results
- 16. Result Fields ✦ Special fields that are returned with each hit ✦ Each field is an array ✦ Also return total number found and “start” index
- 17. How does this help with DynamoDB? ✦ DynamoDB is non-indexed ✦ Stores Metadata only ✦ Can be used to store full metadata for objects that are indexed in CloudSearch ✦ Both are exceptionally fast and scalable
- 18. Its not cheap ✦ Priced per instance and instance type ✦ You do not control scaling, Amazon does ✦ At minimum, approximately $100 per “domain”
- 19. Pricing ✦ $0.12/hour - 1 million documents $87/month ✦ $0.48/hour - 4 million documents $346/month ✦ $0.68/hour - 8 million documents $490/month ✦ $0.10 per 1,000 Batch Put requests
- 20. What to take away from this ✦ CloudSearch is expensive, but saves development time ✦ CloudSearch provides powerful features that would take time to implement yourself ✦ Just like everything else Amazon releases, the price will decrease eventually.
