HBaseCon 2012 | Developing Real Time Analytics Applications Using HBase in the Cloud - Rick Tucker, Sproxil
As small companies are adapting to handle Big Data, the cloud and HBase enable developers to leverage that data to provide revenue-generating real time applications. When developing a real time application for an existing system, one must balance incrementing counters in real time with Map Reduce jobs over the same data-set. When maintaining an analytics platform, ensuring data accuracy is essential. At Sproxil, SMS logs are ingested into HBase at a growing rate and we report metrics such as SMS throughput, unique user growth over time, and return SMS user activity in real time. Sproxil provides a versatile analytics application enabling customers to handpick statistics on demand to gain market insights enabling them react quickly to trends. This talk will identify the most profitable metrics and demonstrate how to calculate them using Map Reduce while continually updating data as it arrives.

- 4. Real-Time Analytics Engine • MapReduce too slow to maintain data in true real time • As data arrives, analytical data is updated through counters Text Message Message Increment Arrives Analyzed Counters Genuine Product +1 Increment Counter for Authentication Genuine Authentications Repeat Customer +1 Increment Counter for Repeat Customers tech@sproxil.com May 22,2012 © 2012 Sproxil, Inc.
- 5. Schema Design: Example 1 • Example: View log of text messages in chronological order • Rowkey: row prefix + timestamp Row transaction 2012-05-22 12:00:00 transaction 2012-05-22 12:01:14 transaction 2012-05-22 12:02:03 Note: HBase sorts rowkeys lexicographically so scans return data in reverse chronological order tech@sproxil.com May 22,2012 © 2012 Sproxil, Inc. 5
- 6. • • Row transaction userID 1 2012-05-22 12:00:00 transaction userID 1 2012-05-22 12:01:14 transaction userID 2 2012-05-22 12:00:54 transaction userID 2 2012-05-22 12:01:22 transaction userID 2 2012-05-22 12:02:01 Note: Hbase sorts rows lexicographically so scans return data in reverse chronological order tech@sproxil.com May 22,2012 © 2012 Sproxil, Inc.
- 7. Critical Findings • Schema design is crucial for successful HBase implementation – Pack as much info as possible into row keys • Use caution with Filters – E.g. Regex filters can be costly – Alternatives: • Directly query for data you need • Use efficient filters when filtering large data sets tech@sproxil.com May 22,2012 © 2012 Sproxil, Inc.
