Extension Highlight

We wanted to highlight some of the fantastic work that is being done by the ecosystem with Postgres Extensions. Although the base of Postgres is the amazing and extensible PostgreSQL, a lot of users don’t realize that Postgres has the feature they are looking for, if only they were to look to the ecosystem.

Notable Extensions:

  • pgaudit : The goal of pgAudit is to provide PostgreSQL users with the capability to produce audit logs often required to comply with government, financial, or ISO certifications.

  • pg_credereum : pg_credereum is a PostgreSQL extension that provides a cryptographically verifiable audit capability for a PostgreSQL database, bringing some properties of blockchain to relational DBMS.

  • H3-pg : PostgreSQL bindings for H3, a hierarchical hexagonal geospatial indexing system.

Postgres can do what?

There are a ton of Postgres compatible features out there. Some of them are overlooked core features and some of them require installing a different version of Postgres. Here are a few examples:

 

  • TimescaleDB: Time series data management with Postgres

  • YugabyteDB: Globally Distributed database with PostgreSQL compatibility

  • Postgres-XL: Horizontally partitioned PostgreSQL

  • Agensgraph: Graph capabilities with Postgres

  • PG-Strom: GPU accelerated extension for Postgres 

 

Upcoming Education and Networking opportunities:

Efficiently and Safely Propagate Data Changes Without Triggers!

 

Prior to PostgreSQL 9.4, the primary way to distribute data-driven changes across multiple tables was to use triggers. While triggers guarantee that these changes will be propagated, they can have a significant impact application performance, both technically and with development time (see: "debugging"). PostgreSQL 9.4 introduced logical decoding, which provides a way to stream all changes in a database to a consumer. Using a logical decoder, you can read all changes that are made in a table into your programming language of choice to perform many tasks: cache invalidation, data propagation, submitting changes to remote services, and more. Many PostgreSQL drivers, such as psycopg2 and JDBC support the logical replication protocol, which lets you easily stream your database changes to be manipulated using your favorite programming language. This talk will demonstrate how you can setup logical decoding for your application, look at architecture strategies for working with a logical decoder, and look at a case-study that shows how using logical decoding led to a big performance boost over a similar trigger-based system.
 
• 7:00 - 7:30:  Kevin Jernigan, Senior Product Manager, Amazon
Technical Architecture of Postgres Aurora 
 
Amazon Aurora is a cloud-optimized relational database that combines the speed and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. The recently announced PostgreSQL-compatibility, together with the original MySQL compatibility, are perfect for new application development and for migrations from overpriced, restrictive commercial databases. In this session, we’ll do a deep dive into the new architectural model and distributed systems techniques behind Amazon Aurora, discuss best practices and configurations, look at migration options and share customer experience from the field. 
 
• 7:30 - 8:20: Joshua (JD) Drake POSTPONED due to flight cancellation)
The Power of Postgres Replication, Postgres Expert - Lead Consultant Command Prompt, Inc and Co-Chair PGConf!
 
With PostgreSQL v10 a new replication engine has come to town. Let's explore Postgres Logical Replication, how to use it, optimize it and let it best fit in with your organization. We will also discuss its interactions with external tools as well as Binary Replication and features such as Hot Standby.

Presenter Professionalism at Postgres Conferences

Andreas Scherbaum recently tweeted, “Speakers: it is NOT OK to even consider drinking alcohol during a talk! No matter how complicated your talk topic is.” The tweet has caused an interesting debate on Twitter and Facebook. It also caused me to run a poll via @amplifypostgres on the matter.

At the time of this writing almost 70% of the votes on the poll either don’t care or don’t think it is unprofessional for a presenter to drink alcohol while presenting.

One of the counter arguments to presenters consuming alcohol during presentations is that when you are presenting you are representing the conference. The conference wants you to be professional and create an environment that represents that during your talk. Fair enough, but why is it unprofessional?

This sequence of events has me wondering: what is professionalism in reference to presenting at Postgres Conferences? It is certainly not appropriate to be intoxicated while presenting at a professional conference, but that isn’t the question. The question is: why is it inappropriate for an adult to make a legal choice to take a nip or sip beer (or wine) during a presentation? Why is that more unprofessional than not wearing a tie or button up shirt, or wearing shorts or a kilt?

Professionalism is subjective.
“In my opinion, my obligations to the audience are:
  • I must care about the content.
  • I must deliver what I say I will deliver.
  • I must be honest with the audience about my level of experience in the subject.
  • I must be honest about my opinions on the subject.
  • I must be a genuine version of me, minus the swearing.”
I fail at “minus the swearing” but the rest are spot on and should be our focus.

If you do not want presenters to consume alcohol during their presentations, then add it to your Code of Conduct. If it’s not in your Code of Conduct, then let adults take responsibility for themselves and present the best content possible for our community, in whatever way necessary.

Rock on and @amplifypostgres!

Disclaimer: I am writing this opinion as a frequent presenter, not as the Co-Chair of the most electrifying Postgres Conference in the world.

Community Profile: Alex Tatiyants and Pev

We caught up with Alex Tatiyants after finding out about his Pev project. This is an awesome web based visual explain analyzer that is similar to the awesome explain.depesz . 

Tell us a little bit (one or two paragraphs) about your project or how you use Postgres: 

I created Pev (Postgres EXPLAIN Visualizer) to scratch my own itch. EXPLAIN generates a wealth of information, but isn’t easy to make sense of. I wanted to create a tool that helps me quickly diagnose problems with queries. Apparently, other people found it useful as well.


Pev plan


Why did you chose Postgres for your project? 


Postgres is a fantastic database: performant, mature, feature rich, and of course open source. And in addition to being a first rate relational database, it has very strong document store features as well.


Have you attended a PgConf US event or do you plan to? 

I haven't had a chance to attend PgConf.

Are you interested in contributing to the community further and if so, in what fashion? 

I don’t have any concrete plans at the moment.

Any closing comments? 

Thank you for your interest.

Community Profile: LLoyd Albin of Fred Hutchinson Cancer Research Center


How do you use Postgres?

I work Fred Hutchinson Cancer Research Center and within Fred Hutch, I work for the largest group called SCHARP, Statistical Center for HIV/AIDS Research and Prevention. We use Postgres to monitor the AIDS drug trials real time to see if the trials are working or not. This means we collect the data from doctors and labs around the world, and analyzing the data. We also have servers where we receive data from other research institutes and share our randomized data, de-personalized, with other research institutes.


What community contributions have you provided?

In 2010 I started SeaPUG, Seattle Postgres Users Group, at the request of Josh Drake. I have at least have the presentations there every year. I have also discovered several PostgreSQL: bugs which have been fixed. Some of them affected every version of PostgreSQL. Bug numbers: 7553, 8173, 8257, 8291. I also found 8545, which has not been fixed but Core has acknowledge needs to be fixed but they are not sure where it should be fixed, pg_dump or pg_dumpall. I started the PostgreSQL track at LinuxFest Northwest in 2014 after my GIS presentation in 2013 was standing room only. This year I got a booth at the SeaGL, Seattle GNU Linux, conference with the idea of having a booth there next year along with also doing a PostgreSQL presentation next year at the conference.


You recently took a renewed interest in speaking at Postgres Conferences, why?

I have been giving presentations locally now for the last 7 years and so I am now ready to move on to the next step, doing presentations at the Local and National conferences around the United States.


What is the #1 barrier you see to Postgres adoption?

People not knowing about PostgreSQL, most people know about MYSQL, MSSQL and Oracle, but do not know about PostgreSQL. This is changing, some, with the Cloud providers now offering PostgreSQL, but I go to these conferences, LinuxFest Northwest and SeaGL, and people all the time are asking me, "What is Postgres and why should I use it over MYSQL, MSSQL or Oracle", because they have never heard of PostgreSQL.


What is something you feel the wider Postgres community could be better at?

We need to promote PostgreSQL so that new people starting personal projects and starting at companies, will think about PostgreSQL before other databases. This starts with getting the younger generation interested in PostgreSQL and that also means that we need to get the college professors willing to talk about PostgreSQL in their curriculums instead of ignoring PostgreSQL for all the other competing databases. Some of this means that at all the other conferences, we need to have a PostgreSQL presence, aka booth and presentations. We should also come up with a certification method for PostgreSQL DBA's, User's, Engineer's, etc so that prospective employers will have an idea of the prospective employees skill set.

PGConf US Local: Seattle CFP reopened and three new tracks added!

Oh my goodness, Data Days!


When we rescheduled PGConf US Local: Seattle from August to November we did so due to attendee feedback. It was amazing - people didn't want to go to a conference on Saturday in August (I wonder why). I know, we should have known but it was a new model and we tried. We are extremely pleased with the results of the shift in schedule. The conference now takes place during "professional hours" on "professional days."

Image result for creative commons professional

Because of the shift and sponsor support we have added three new tracks, reopened the CFP, and created Data Days. The new tracks are: Big Data, AWS/Cloud, and Data Science. As these three Postgres content areas are Postgres independent we are also requesting that all communities within this realm submit to present. Let's turn PGConf US Local: Seattle into not only the best West Coast Postgres Conference but also the most highly integrated, heterogeneous data event in the Pacific Northwest.

CFP Dates:

  • Open until: 10/15/2017
  • Notification:  10/18/2017
  • CFP Link
