The 2nd South Bay PostgreSQL Meetup.
This is not a competitive event to the PG Meetups in SF, but rather aims to provide a platform for anyone in the South Bay who wants to avoid the traffic jams in SF.
We aim to host a Meetup every other month.

CK Tan: Vitesse DB: 100% PostgreSQL, 100 Times Faster for Analytics
Vitesse DB is PostgreSQL for data warehouse. Rapid advances in memory, SSD, and core-count have produced affordable, powerful computers that comfortably fit the working sets of most DW queries on a single machine without resorting to MPP. Unfortunately, processing speed and single-threaded limitations have precluded PostgreSQL from DW applications.
In this talk, we will describe how we made TPCH Q1 run more than 100X faster on a Postgres instance. In particular, how we dramatically increase per-core efficiency of the Executor using LLVM for dynamic query compilation, and how we thread and scale query execution across many cores efficiently, yet still maintain 100% compatibility with PostgreSQL.
Heikki Linnakangas: pg_rewind - resynchronizing servers after failover
pg_rewind is a tool that makes it possible to resynchronize an old master server after a failover, witout having to make a new base backup. In this presentation, I will explain the problems involved with failover and failback, how pg_rewind works, and demonstrate how to use it.
