PDXPUG February 2020 Meetup: DBlink and SQL/MED and FDW, oh my! External Data Access tricks

2020 February 20 Meeting 6pm-8pm

Location:

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

Speakers: Gabrielle Roth & Michelle Franz

In February, long-term PDXPUGers Michelle Franz & Gabrielle Roth return to discuss DBLINK and FDW, two methods of accessing data that’s outside your database. We’ll briefly mention SQL/MED on the way, and tell a couple of bad (Dad) jokes.

We’ll cover use (and mis-use) cases, configuration of each, and interesting quirks. Gabrielle will attempt a live demo of file_fdw and postgres_fdw. You’re welcome to follow along if you’d like, just show up with a couple of Pg databases: they can be on the same cluster (or container or RDS instance or what have you) or different ones, doesn’t really matter. One of them should have at least one table with data in it.

About the speakers:

From embedded systems to UI to relational database programming, Michelle’s running an interesting path through the software world. Working with databases is her current episode, with some programming, some DBA, some SysAdmin and a healthy dose of learning agile. She’s very quickly come to appreciate and enjoy working with Postgres and her work has allowed her to learn from some super talented database experts.

Gabrielle has been using Postgres since sometime in the version 7s, and thinks that the best part of using Open Source software is the culture of sharing knowledge. She’s a Senior Data Engineer at NS1 and co-founder and former co-lead of PDXPUG.

PDXPUG January 2020 Meetup: Interacting with databases as API’s

2020 January 16 Meeting 6pm-8pm

Location:

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

Speaker: Alex Theodore

As a CTO I saw everything that went into and came out of the web development process, from the “client needs” to the source-controlled code. But being skilled in database development showed me time and time again that databases (and their architecture) were often sidelined treated as after-thoughts and often times served as little more than flexible storage spaces. Yet, their contents were the very essence of value for the process/client/company being served. This strange inversion of priorities led me to develop a way of looking at databases as “outside” the application and ultimately to interacting with them as API’s. In my talk I’ll be presenting this concept and showing with simple rules and examples how it can be done.

Bio:

I was the product and technology founder of Fracture.me and CTO up until 2018 where I developed the manufacturing processes and ERP software that powered our production process. That got me deeply involved in database work, especially with architecture and process design and optimization. Now I work part time as a database consultant and part time building modern, minimalistic furniture for my new (small) company MillFinish.com.

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.

PDXPUG June Meetup: Accessing Postgres with Java

When: 6-8pm Thursday June 20, 2019
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.
