- 5. Big Data is not new! but the tools are. 5
- 6. The Good News in Big Data: “Simple algorithms and lots of data trump complex models” Halevy, Norvig, and Pereira, Google IEEE Intelligent Systems 6
- 7. The Challenge: So Many Solutions! What solutions fit your business problem? For example, do you need… Apache Mahout? Storm? Apache Solr/Lucene? Apache HBase (or MapR M7)? Apache Drill (or Impala?) d3.js or Tableau? Node.js 7 Apache Hadoop? Titan? 7
- 8. Ask a Different Question It may be more useful to better define the problem by asking some of these questions: How large is the data to be queried? (the analysis volume) What time frame is appropriate for your query response? How fast is data arriving? (bursts or continuously?) Are queries by sophisticated users? Are you looking for common patterns or outliers? 8 How large is the data to be stored? How are your data sources structures? 8
- 9. Picking the Best Solution Your responses to these questions can help you better: define the problem recognize the analysis pattern to which it belongs guide the choice of solutions to try But first, here’s a quick review of a few of the technologies you might choose, and then we will focus on three of the questions as a part of the landscape. 9 9
- 10. Apache Solr/Lucene Solr/Lucene is a powerful search engine used for flexible, heavily indexed queries including data such as Full text Geographical data Statistically weighted data Solr is a small data tool that has flourished in a big data world 10
- 11. Apache Mahout Mahout provides a library of scalable machine learning algorithms useful for big data analysis based on Hadoop or other storage systems. Mahout algorithms mainly are used for Recommendation (collaborative filtering) Clustering Classification Mahout can be used in conjunction with solutions such as Solr: You might use Mahout to create a co-occurrence data base that could then be queried using a search tool such as Solr 11
- 12. Apache Drill Google Dremel clone Pluggable Query Languages – – Pluggable Storage Backends – – – Starts with ANSI SQL 2003 Hive, Pig, Cascading, MongoQL, … Hadoop, Hbase MongoDB (BSON) RDBMS? Bypasses MapReduce 12
- 13. Storm Realtime Stream Computation Engine Horizontal Scalability Guaranteed Data Processing Fault Tolerance Higher level abstraction over: – – Message Queues Worker Logic “The Hadoop of Realtime” 13
- 14. Titan Distributed Graph Database Property Graph Pluggable Backend Storage – – – Search Integrated – – HBase or M7 Cassandra Berkeley DB Solr/Lucene Elastic Search Faunus – – Graph traversals on subset In-memory 14
- 15. Using the Answers to Guide Your Choices For simplicity, let’s focus in on the first three questions: How large is the data to be stored? How large is the data to be queried? (the analysis volume) What time frame is appropriate for your query response? 15
- 16. Big Data Decision Tree How big is your data? <10 GB mid ? ? A Single element at a time >200 GB What size queries? One pass over 100% B Response time? C Big storage Multiple passes over big chunks Streaming < 100s (human scale) D 16 throughput not response E
- 17. Use Cases Company Data Shape Technique(s) Business Value 17
- 21. Telecommunications Data Shape Lots of Data Lots of Queries across Large Sets Throughput important 21
- 26. Credit Card Issuer Data Shape Customer Purchase History (big) Merchant Designations Merchant Special Offers Throughput important Recommendations 26
- 27. Search Abuse Techniques A Recommendation Engine with Mahout and Solr/Lucene History matrix One row per user One column per thing 27
- 28. Techniques Recommendation based on cooccurrence Cooccurrence gives item-item mapping One row and column per thing 28
- 29. Techniques Cooccurrence matrix can also be implemented as a search index 29
- 31. Techniques User history SolR SolR Indexer Solr Indexer search Web tier 8Hrs 3 Min Item metadata Index shards 31
