January meeting next week!

When: 7-9pm Thu Jan 16, 2014
Where: Iovation
Who: Peter Geoghegan
What: "Something UPSERT-y"

Peter Geoghegan, currently an engineer at Heroku, has made a number of
notable contributions to PostgreSQL:
- Modifying pgstatstatements, the contrib module that logs frequently
executed queries, to support the normalization of non-prepared queries.
- Contributing a performance optimization to PostgreSQL 9.2, with which the
sorting of scalar types like integers has been considerably sped-up. This
has been observed to result in an over 30% performance improvement in
execution time for some simple queries with ORDER BY clauses, an
improvement that holds up well as the size of the underlying table grows.
- Introducing a series of changes to PostgreSQL to improve its power
consumption when idle, by eliminating the busy-waiting that previously
prevented CPUs from entering idle states.

Peter's going to talk about his work on UPSERT and logical replication.

Our meeting will be held at Iovation, on the 32nd floor of the US Bancorp
Tower at 111 SW 5th (5th & Oak). It's right on the Green & Yellow Max
lines. Underground bike parking is available in the parking garage;
outdoors all around the block in the usual spots. No bikes in the office,
sorry!

Building security will close access to the floor at 7:30.

See you there!
