Seattle Postgres and People, Postgres, Data were present at the 20th Anniversary Event of LinuxFest Northwest this weekend! The “Fest” is a conference built around Free and Open Source Software, taking place in Bellingham, Washington. It is a true gathering of over 2000 Open Source practitioners. There was also a well attended Postgres Track and an “Ask the experts” panel.

Highlighted Find

Also at LinuxFest Northwest was YottaDB. YottaDB uses the PostgreSQL wire protocol to allow universal driver access to their in-memory transactional database. This has become a popular way to utilize the maturity of the PostgreSQL code base and reduce overhead in having to maintain a protocol and drivers.

People, Postgres, Data and The World’s Database

The World’s Database celebrates all of Postgres, including whichever version, fork, or hybrid used to build yourself, your business, or your hobby. We have Open and Closed Source technologies. We have amazing extensions (TimescaleDB), unique implementations (Yugabyte), and respected forks to solve specific problems such as Greenplum, Azure, and Aurora. We have meetups where professionals can gather to collaborate and network in all major U.S. markets. Most importantly we are an inclusive community celebrating everything surrounding the maturity, extensibility, and growth of the Postgres ecosystem.

PGConf US and Austin PUG organized a PGConf Mini last night. It was three presentations over the evening. We had good attendance and excellent community participation. The highlight of the evening was PGConf US Co-Chair Jim Molgendski's presentation, "Top 10 Mistakes When Migrating from Oracle to PostgreSQL".

We tried something new this time around. We utilized Twitter's Periscope capability to live stream his presentation. It wasn't perfect but it was our first time and we are looking forward to utilizing the platform more in the future.

Click here to watch "To Mistakes When Migrating From Oracle to PostgreSQL", and then submit a presentation to one of our upcoming conferences:

• PGConf US Local: Philly

• 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.”

Pivotal Sponsor Highlight Blog for PostgresConf 2019

Written by:

Jacque Istok, Head of Data, Pivotal

1. Greenplum has its own community; what do you hope to achieve by joining the Postgres community and PostgresConf?

Both interest and adoption of Postgres have skyrocketed over the last two years, and we feel fortunate to be a part of the extended community. We have worked very hard to uplevel the base version of Postgres within Greenplum to more current levels and to be active in the Postgres community. We see Greenplum as a parallel (and analytic focused) implementation of Postgres, and we encourage the community to continue to embrace both the technology and the goal of the Greenplum project, which is Postgres at scale.

2. Are you planning to provide any new tech (PG features, etc.)?

This year we plan to announce several new things for both Greenplum and Postgres. We’re introducing new innovations in our cloud offerings in the marketplaces of AWS, Azure, and GCP. We also have major news about both our natural language at-scale analytics solution based on Apache Solr, and our multi-purpose machine learning and graph analytics library Apache MADlib. The next major release of Greenplum is a major focus as well, differentiating Greenplum from each of its competitors and bringing us ever closer to the latest versions of Postgres.

3. Are there any rising stars in the community you’d like to give props to?

While it seems a little self-serving, I would like to take the opportunity to give props to the Pivotal Data Team. This team is a 300+ worldwide organization that helps our customers, our prospects, and the community to solve real world and really hard data problems—solved in part through Postgres technology. They all attack these use cases with passion and truly make a difference in the lives of the people that their solutions touch. I couldn’t wish to work with a finer group.

4. What is the number one benefit you see within Postgres that everyone should be aware of?

The number one benefit of Postgres is really its flexibility. This database chameleon can be used for SQL, NoSQL, Big Data, Microservices, time series data, and much more. In fact, our latest analytic solution, MADLib Flow, leverages Postgres as an operational engine. For example, Machine Learning models created in Greenplum can be pushed into a restful API as part of an agile continuous integration/continuous delivery pipeline easily and efficiently—making Postgres the power behind what I still like to think of as #DataOps.

5. What is the best thing about working with the Postgres community?

I deeply admire the passion and consistency of the community behind Postgres, constantly and incrementally improving this product over decades. And because Greenplum is based on Postgres, we get to interact with this vast community of talent. We are also able to more seamlessly interact with ecosystem products that already work with Postgres, making the adoption of Greenplum that much easier.

6. Tell us why you believe people should attend PostgresConf 2019 in March.

PostgresConf is going to be awesome, and I can’t wait for it to start! With Pivotal, Amazon, and EnterpriseDB headlining as Diamond sponsors, Greenplum Summit (along with multiple other summits), and high-quality speakers and content across the board, this year’s PostgresConf promises to be bigger and better than ever and surely won’t disappoint.

We’re thrilled to be back to present the second annual Greenplum Summit on March 19th at PostgresConf. Our theme this year is “Scale Matters”, and what we’ve seen with our customers is that every year it matters more and more. Our users are part of organizations that are generating tons of data and their need to easily and quickly ingest and interrogate all of it is paramount. This is true even more now than ever before as the insights that can be found not only help differentiate them from their competitors, but are also used to build better products and increase customer loyalty.

The day will be filled with real-world case studies from Greenplum users including Morgan Stanley, the European Space Astronomy Centre, Insurance Australia Group, Purdue University, Baker Hughes (a GE company), Conversant, and others, plus presentations and deep-dive tech sessions for novices and experts alike.

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.

Tell us about your commitment and contribution to the Postgres Community

For over 10 years, EnterpriseDB (EDB) has been working with the community and enterprises to drive Postgres forward. EDB is one of the top PostgreSQL community contributors. Two of our team members are part of Postgres Core team, while 4 are committers, and 6 are named contributors. We invest heavily into Postgres performance, scalability, availability, migration, integration and support to make sure that enterprises can take advantage of Postgres' rapid innovation cycle and advanced capabilities.

What growth pattern do you expect for yourself as well as Postgres as a whole?

Postgres adoption is exploding and we can see that in our business results. Today, we support 92 of the Fortune 500 and 311 of the Forbes Global 2000. Our customers look to us for a reliable, high-performing, and cost-effective data management platform based on open source PostgreSQL.

Our customers are using EDB Postgres for mission critical applications. Their databases range all the way up to 50 TB with some handling over 50K transaction per second in environments that require 99.99%+ availability.

Our customers’ confidence in Postgres and EDB is no surprise. Postgres has been the #1 open source relational database in the DB-Engines.com rankings for two years in a row and EnterpriseDB has been chosen for the Gartner Magic Quadrant for Operational Database Management Systems for six years in a row.

How do you plan to assist Postgres in the future?

EDB continues to invest heavily in Postgres with key projects such as zHeap, Just-in-Time (JIT) compilation, and other efforts focused on performance and scalability.

What is the number one benefit you see within Postgres that everyone should be aware of?

EDB Postgres has become the general purpose database of choice for digital transformations, offering JSONB document support, GIS-support, EDB Postgres Oracle® compatibility features, key-value pair data, and increasing capabilities for analytical workloads. It has the fastest innovation cycle, the best deployment models, and the lowest cost of any commercial relational database.

What is the best thing about working with the Postgres community?

The best thing about working with the Postgres community is their fast innovation, resulting in extremely reliable code.

Tell us why you believe people should attend PostgresConf 2019 in March.

PostgreSQL is one of the oldest and most stable open source projects as a result of the commitment of its members and its independence as a stand-alone community. Over the years, Postgres has achieved parity with proprietary platforms in terms of performance and functionality. It has received a warm welcome from businesses looking to roll back database costs and ease vendor lock-in, and leading companies are adopting it with great success. This is just like it was with Linux 15 years ago. Enterprises understand that they have to adopt Postgres or they will be left behind.

Like most conference organizers we are learning to adapt to the new world; a world where physical events are no longer viable (at least in 2020). A world where people are genuinely and realistically concerned that an in-person event would increase their chances of receiving or spreading a life threatening virus.

The question is: Are in-person events a thing of the past?

The answer to that question is a difficult one. Our friends at O'reilly and Associates have permanently canceled their in person events. Our friends in Europe recently canceled the well respected PgConf.EU and Ibiza. We had to cancel our 2020 marque event in NYC in March and our upcoming Silicon Valley conference. The local community organizer website Meetup.com has even modified their capabilities to allow for online meetups. 

Humans in general seek out fellow human contact. That contact is usually of reasonably like minded individuals or at least mutual interests. This is why events like Postgres Conference are successful, because irrespective of any personal beliefs we are all there to learn and enjoy fellow Postgres professionals. But are virtual meetups and conferences going to be enough to satisfy that connection or are people going to demand a return to a historical norm?

Challenges

Even before COVID-19, in-person events came with challenges that put significant pressure on volunteers. Between cultural communication differences, having an independent Code of Conduct committee, pricing, economies of scale, partner demands, and now social distancing, conferences are now going to be more complicated than ever. A room that once could comfortably seat 100 can now only properly sit 30. An exhibit hall is likely out of the question and one-on-one mentoring and networking are likely not going to be viable.  How do we work around these limitations? Is it worth it? Are the people in our community even interested anymore or is it time to accept a new norm?

Opportunity

Without question this is a time of reflection, continued development of relationships, and looking into the magic 8-ball; a continual asking of questions to find the right path forward. The pandemic is a tough foe but true leaders are looking forward and trying to find ways to continue to serve. For that to be successful we need your help. We have put together a poll (that can be found here) to gain insight into what opportunities we may be able to pursue in the future. Please take a couple minutes and help shape the future of Open Source events. 

As a closing, we are actively moving forward with Digital Events across the globe and have an unending Call for Presentations open for Webinars. If you have any feedback or brilliant ideas, please send them to us via organizers@postgresconf.org.

Blatant Poll Link 

The Chairs (myself, Jim Mlodgenski, and Amanda Nystrom) have recently decided to bring some visibility to charities that are close to our hearts. They are listed below:

• Joshua Drake: Navajo Water Project. The Navajo nation is approximately the size of West Virginia and has a population of over 150,000 people (300k in the tribe). Anywhere from 15% - 40% of the residents do not have access to running water. The Navajo Water Project aims to bring clean water to each person and family through support from those that donate. 
• Jim Mlodgenski: St. Jude Children’s Research Hospital. The hospital is one of the premier research hospitals for cancer and other life threatening illnesses for some of our most vulnerable people. Approximately one in 285 children in the U.S. will be diagnosed with cancer before their 20th birthday. Through donations, St. Jude’s provides treatment to those with cancer, and is actively dedicating resources to the research and cure for cancer. 
• Amanda Nystrom: ASPCA. The American Society for the Prevention of Cruelty to Animals (ASPCS) was the first humane society to be established in North America, with the goal of providing kind and respectful treatment to animals under the law. Unlike humans, cases of animal abuse aren’t compiled but studies have shown a correlation between domestic violence and animal abuse. The ASPCA prevents animal homelessness and actively rescues animals from dangerous and/or cruel situations.
