PDXPUG October Meetup: Terminal Tools & Database Statistics

2019 October 17th Meeting 6pm-8pm

Location:

PSU Business Accelerator
2828 SW Corbett Ave · Portland, OR
Parking is open after 5pm.

Speaker: Mark Wong

pg_top was born in 2007 from a fork of the unixtop, a terminal program displaying top processes on the system, where pg_top focuses on the processes with the PostgreSQL database you are connected to. Recently pg_systat was forked from systat to display additional database statistics.

These tools have can help do more such as explore query execution plans and create reports from system and database resources.

Come learn about the statistics PostgreSQL keeps and how to use these tools to view them.

Mark leads the 2ndQuadrant performance practice as a Performance Consultant for English Speaking Territories, based out of Oregon in the USA. He is a long time Contributor to PostgreSQL, co-organizer of the Portland PostgreSQL User Group, and serves as a Director and Treasurer for the United States PostgreSQL Association.

PDXPUG September meetup: Sharding large MySQL databases with Vitess

When: 6-8pm Thursday September 19th, 2019
Where: PSU Business Accelerator (Parking is open after 5pm.)
Who: Grant Holly

This month I am going to be talking about my current work on sharding large mysql databases with Vitess.  My team has been on a journey towards splitting our largest mysql databases and I want to share my experiences and lessons learned.  We are going to look at the problems and possible solutions to scaling reads and writes in relational databases.

Vitess is an open source project born at youtube to scale their largest and most critical databases.  It has been adopted in as a Cloud Native Compute Foundation incubator project.  With PostgreSQL on the medium-term road map, let’s take a look at what we have been able to do with mysql.

Hi its me Grant.  I work on the database engineering team at New Relic.  I’ve been using Postgres in production since 9.2.  I co-organize the Postgres user group in Portland with Mark Wong.

PDXPUG August Meetup: PostGIS

When: 6-8pm Thursday August 15, 2019
Where: PSU Business Accelerator (Parking is open after 5pm.)
Who: Jackson Voelkel

Jackson will discuss the basics of GIS, and the current environment in which enterprise spatial analytics are performed. Considering the many pitfalls of this current system, he will discuss how FOSS tools – especially PostgreSQL/PostGIS – are vitally important for modern spatial analytics. In addition to the PostGIS extension, Jackson will talk about network routing using the PgRouting extension and the interface between R and PostgreSQL. This talk will act more as a showcase of GIS and “spatial SQL” within PostgreSQL than it will nitty-gritty database development.

Jackson Voelkel is a Health Data Analyst on Kaiser Permanente’s GIS Team as well as an Adjunct Professor of Geography at Portland State University. He focuses on developing infrastructure for and performing advanced spatial analytics across healthcare, environment, urban planning, utilities, and econometrics. He teaches courses on advanced spatial analytics in R as well as spatial database design with PostgreSQL/PostGIS.

Where: PSU Business Accelerator (Parking is open after 5pm.)
Who: Will McLean

To follow the presentations on accessing Postgres from Python and Scala, I will lead a discussion on accessing Postgres with Java. I’ll start with a jdbc tutorial and finish with adding data access to a springboot webapp.

I have twenty years experience in e-commerce applications, the last eight here in Portland, mostly at Nike.For the last few years everything has been moving to Amazon RDS Postgres, that’s a trend pdxpug can get behind!  I am currently working for Navis on CRM applications for the hospitality industry.

What: Disaster Recovery and High Availability Planning

Learn about the considerations in planning for disaster recovery in order to maintain business continuity. There are solutions available that can help you achieve your backup and recovery objectives by taking advantage of PostgreSQL features, such as point-in-time recovery, and help implement retention policies.

Also learn how to take advantage of PostgreSQL’s replication features to keep your database highly-available, and the basic cluster architectures to consider to keep a PostgreSQL cluster up and running.

PDXPUG April Meetup: Postgres with non-blocking IO and Scala

2019 April 18th Meeting 6pm-8pm

Location:

PSU Business Accelerator
2828 SW Corbett Ave · Portland, OR
Parking is open after 5pm.

Speaker: Grant Holly

This month I will be demonstrating using non-blocking IO database access using Scala and the Slick library.  No really, the library is called Slick AND it is very cool to use.  Slick and Scala are great for working with Postgres with either straight SQL, or using the FRM (that’s a Functional Relation Mapper like in functional programming).  After Hannah gave a great talk talk about Python, Postgres, and ORMs, I got to thinking that I could do a language and ORM talk.  Thanks Hannah, that was great.
