This talk introduces an open-source SQL-based system for continuous or ad-hoc analysis of streaming data built on top of the Flume data collection platform for Hadoop.
Big data analytics based on Hadoop often require aggregating data in a large data store like HDFS or HBase, and then running periodic MapReduce processes over this data set. Getting “near real time” results requires running MapReduce jobs more frequently over smaller data sets, which has a practical frequency limit based on the size of the data and complexity of the analytics; the lower bound on analysis latency is on the order of minutes. This has spawned a trend of
building custom analytics directly into the data ingestion pipeline, enabling some streaming operations such as early alerting, index generation, or real-time tuning of ad systems before performing less time-sensitive (but more comprehensive) analysis in MapReduce.
We present an open-source tool which extends the Flume data collection platform with a SQL-like language for analysis over streaming event-based data sets. We will discuss the motivation for the system, its architecture and interaction with Flume, potential applications, and examples of its usage.
Aaron Kimball is the CTO of Zymergen, Inc. Zymergen uses high-throughput techniques, combined with big data analysis, to improve genetic strains for microbial chemical production. Aaron has been working with Hadoop since 2007. In 2008 he was Cloudera’s first employee, where he wrote Apache Sqoop and MRUnit, as well as performed a lot of Hadoop training. In 2010, Aaron founded WibiData and assumed the role of chief architect. WibiData helps organizations build big data applications. Aaron holds a BS in computer science from Cornell University and an MS in computer science from the University of Washington.
