Eric Kalabacos, Vice President of Solutions, Splice Machine

A Database Month event

This presentation will describe the architecture and implementation of Splice Machine V2.0, an open-source database that combines the benefits of modern lambda architectures with the full expressiveness of ANSI-SQL.

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). Like typical lambda architectures, it employs separate compute engines for different workloads - some call this an HTAP database (Hybrid Transactional and Analytical Platform).

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 also compare the process of executing queries on Splice Machine versus other HTAP systems such as Apache Phoenix and Apache Trafodian, and discuss future items on the roadmap for development, including new row-based and column-based storage encodings.

Did you know that innovative use of technology-education is going to end this extreme homeless-epidemic in America in the next few years?

The Techie Youth charity provides free computer-career training to severely-at-risk youth who are statistically-likely to become homeless or incarcerated in the next 18-24 months. Most of the Techie Youth kids are in foster care (children without parents, removed from extremely-abusive/neglectful homes), are kids living in homeless shelters, transgendered/LGBQ teens or youth in juvenile-justice "2nd chance prison-alternative" programs. Techie Youth pivots the life-direction for these kids and helps them begin a career as an IT-professional, and a life as a responsible self-sustaining young-adult.
