Hadoop Streaming: Programming Hadoop without Java
An introduction to using Hadoop Streaming to write map/reduce functions without knowing Java. Includes examples written in Python.

Splice Machine is an open-source database that combines the benefits of modern lambda architectures with the full expressiveness of ANSI-SQL. Like lambda architectures, it employs separate compute engines for different workloads - some call this an HTAP database (Hybrid Transactional and Analytical Platform). This talk describes the architecture and implementation of Splice Machine V2.0. The system is powered by a sharded key-value store for fast short reads and writes, and short range scans (Apache HBase) and an in-memory, cluster data flow engine for analytics (Apache Spark). It differs from most other clustered SQL systems such as Impala, SparkSQL, and Hive because it combines analytical processing with a distributed Multi-Value Concurrency Method that provides fine-grained concurrency which is required to power real-time applications. This talk will highlight the Splice Machine storage representation, transaction engine, cost-based optimizer, and present the detailed execution of operational queries on HBase, and the detailed execution of analytical queries on Spark. We will compare and contrast how Splice Machine executes queries with other HTAP systems such as Apache Phoenix and Apache Trafodian. We will end with some roadmap items under development involving new row-based and column-based storage encodings.
Speakers:
Monte Zweben, is a technology industry veteran. Monte’s early career was spent with the NASA Ames Research Center as the Deputy Chief of the Artificial Intelligence Branch, where he won the prestigious Space Act Award for his work on the Space Shuttle program. He then founded and was the Chairman and CEO of Red Pepper Software, a leading supply chain optimization company, which merged in 1996 with PeopleSoft, where he was VP and General Manager, Manufacturing Business Unit. In 1998, he was the founder and CEO of Blue Martini Software – the leader in e-commerce and multi-channel systems for retailers. Blue Martini went public on NASDAQ in one of the most successful IPOs of 2000, and is now part of JDA. Following Blue Martini, he was the chairman of SeeSaw Networks, a digital, place-based media company. Monte is also the co-author of Intelligent Scheduling and has published articles in the Harvard Business Review and various computer science journals and conference proceedings. He currently serves on the Board of Directors of Rocket Fuel Inc. as well as the Dean’s Advisory Board for Carnegie-Mellon’s School of Computer Science.
