20. Hadoop also
has a
future
©MapR Technologies - Confidential 21

21. The Old Future of Hadoop
 Map-reduce and HDFS
– more and more, but not really different
 Eco-system additions
– Simpler programming (Hive and Pig)
– Key-value store
– Ad hoc query
 Stands apart from other computing
– Required by HDFS and other limitations
©MapR Technologies - Confidential 22

22. The New Future of Hadoop
 Real-time processing
– Combines real-time and long-time
 Integration with traditional IT
– No need to stand apart
 Integration with new technologies
– Solr, Node.js, Twisted all should interface directly
 Fast and flexible computation
– Drill logical plan language

23. Example #1
Search Abuse

24. History matrix
One row per user
One column per thing
©MapR Technologies - Confidential 25

25. Recommendation based on
cooccurrence
Cooccurrence gives item-item
mapping
One row and column per thing
©MapR Technologies - Confidential 26

26. Cooccurrence matrix can also be
implemented as a search index

29. Objective Results
 At a very large credit card company
 History is all transactions, all web interaction
 Processing time cut from 20 hours per day to 3
 Recommendation engine load time decreased from 8 hours to 3
minutes
