Pavan Deolasse is a PostgreSQL consultant for 2ndQuadrant, one of our Platinum Sponsors for PostgresConf US 2018. Learn more about Pavan in this Community Profile:

Pavan Deolasee is a contributor to the development of PostgreSQL and related technologies. He holds a Masters of Technology in Computer Science from the Indian Institute of Technology, Bombay, and has several publications to his credit.

Pavan was introduced to PostgreSQL in the year 2006 when he started working for a PostgreSQL company. Hacking PostgreSQL was a completely new experience, but by accepting help from the community -- especially Simon Riggs, his mentor -- he began working through the code and was soon working on a very important project (Heap-Only-Tuple aka HOT). It was a very complicated piece of work, yet one of the landmark features in PostgreSQL and to this day remains one of his most important contributions to the project. Pavan has since contributed several patches to PostgreSQL. 

HOT was committed to PostgreSQL in 2008 and Pavan has continued to stay fully engaged with the project. In 2009/2010, alongside other colleagues, Pavan started work on Postgres-XC, a distributed, shared-nothing, clustering solution based on PostgreSQL. He was involved in designing the high-level architecture of the solution, and later wrote many important pieces of the code such as the GTM, the GTM Proxy, the 2PC transaction controller at the coordinator, changes required to guarantee global consistency of the data, and many distributed planner and executor pieces.

When Postgres-XL, a fork of Postgres-XC, was released to the public in 2014, Pavan once again became involved with the project and has been leading the development of Postgres-XL ever since. 

Pavan joined 2ndQuadrant not long after in April 2015, and once again started working with long time colleagues and friends; he and 2ndQuadrant have continued to actively work on the development of Postgres-XL. The focus area of development has been stability and performance of the product while keeping the fork as close to open source PostgreSQL as possible. The most recent release (Postgres-XL 10) supports intra-datanode query parallelism, thus taking distributed query processing to the next level.

In 2013, Pavan and two of his colleagues started the India PostgreSQL User Group. They started conducting small meet-ups, in order to promote the technology in India and bring the local community together. These small gatherings have now expanded with a membership of over 600 members, and into a full scale conference: PGConf India, Asia's largest PostgreSQL conference with more than 250 people in attendance each day in 2018. 

As part of the 2ndQuadrant team of PostgreSQL developers, Pavan continues to work on many interesting new features. He is an active part of the production support team and also has the opportunity to investigate interesting customer problems, often leading to important and critical bug fixes to the open source project.

Pavan had this to say about his involvement with the project:

“I love PostgreSQL and the PostgreSQL community, so you will continue to see me around.”

Tom Limoncelli is the SRE Manager at StackOverflow.com and author of Time Management for System Administrators (O'Reilly). He is co-author of The Practice of System and Network Administration (3rd edition just released) and The Practice of Cloud System Administration.  

Tom will be presenting a half-day training on Monday, April 16 on "Personal Time Management: The Basics for Overloaded People." Read what he has to say about Postgres and why to attend his session:

Why PostgreSQL? What got you into it, and made you stick with it?

The startup I was at in 2003 needed a database. Since we did a lot of work with IP and network addresses, we picked PostgreSQL because it supports those as native types.

Tell us about your involvement with the greater Postgres community. 

I'm new to the greater Postgres community. I've been a system administrator since 1988 and often speak on related topics.

What features should be developed/improved and released in the next major upgrade?

Anything that makes replication and failovers easier and more reliable. 

Why should attendees come to your talk at PostgresConf US 2018? What would you like for them to take away from your session?

Time management: you will gain an additional day out of every week. Radical ideas: you'll learn how modern software ("distributed computing") is radically changing how we build systems and do operations. I'd like to give them hope for the future.

What is your favorite aspect of PostgresConf US?

That it's in my back yard!  I live 10 miles from here!

What advice would you have for a Computer Science graduate or entry level developer who are interested in learning and engaging with Postgres?

Give yourself projects. Try to break things and then see if you can repair them.  You'll learn more from recovering a failed system than anything else.

Bonus Question: You can invite any three living people from anywhere in the world to dinner. Who do you invite and why?

Obama (because I'd like to thank him), Steve Martin (because he has an amazing life story and is super smart), and Jennifer Lawrence (she also has an interesting life story).  I also think that these three people would get along well.

Baron Schwartz is the founder and CEO of VividCortex, the best way to see what your production database servers are doing. Baron has written a lot of open source software, and several books. He’s focused his career on learning and teaching about performance and observability of systems generally (including the view that teams are systems and culture influences their performance), and databases specifically.

Baron will be presenting a breakout session "How To Index Your Database" on Friday, April 20th at 12:50 pm. Read what he has to say about Postgres and why to attend his session: 

Why PostgreSQL? What got you into it, and made you stick with it?

The community has always been what’s drawn me to Postgres. From the very first I could immediately sense the deep commitment people had to the database and other people involved with the database. Each database community is special in its own way and has its own culture, and after being involved in many of them you sense it in a way you can’t explain. Postgres’s is loyal to freedom, independence, quality, and principles. All are dear to me as well.

Tell us about your involvement with the greater Postgres community.

I’ve participated since 2008 in various ways. I’ve blogged, written open source, written books, reviewed and tech-edited other people’s books, spoken, and attended. I hope to continue doing so!

What new features of PostgreSQL 10 are you most excited about?

Partitioning! Improved streaming replication! Parallel query execution! There are so many improvements. The pace of development is really impressive.

What features should be developed/improved and released in the next major upgrade?

The database of the microservices-oriented future is only quasi-stateful. By this I mean that it acts almost like a read-through cache in front of “cold storage” like S3. Support for creating an empty database cluster, and having it fetch its data from cold storage on first query, would be game-changing for cloud-native apps. I realize that’s a lot of buzzwords, but it’s going to happen soon!

Why should attendees come to your talk at PostgresConf US 2018? What would you like for them to take away from your session?

Indexing is at once the most important, simplest, and most complicated topic in designing a database; I hope to make it simpler and leave people with three big things they will never struggle to remember.

What sessions are you most excited about attending at PostgresConf US 2018?

I'm really interested in hearing how others are using Postgres, both for creative purposes that showcase its flexibility and extensibility, as well as "use as designed." In my opinion, the best conference talks aren't "you should do this"; types of talks: they are "I did this and here's what happened"; I love stories!

What is your favorite aspect of PostgresConf US?

That’s an easy one to answer: seeing all my old friends again!

What advice would you have for a Computer Science graduate or entry level developer who are interested in learning and engaging with Postgres?

Computer Science seems to feel that algorithms, data structures, and so on are fundamental. Data persistence, especially relational, is equally important. Don’t neglect.

You can invite any three living people from anywhere in the world to dinner. Who do you invite and why?

I invite the three hungriest people in the world and eat mindfully with them, so I learn to appreciate what I have.

As part of the countdown to PostgresConf US 2018, learn more about about featured Platinum Sponsor 2ndQuadrant, including their commitment to partnering with and contributing to the Postgres community, from Simon Riggs, Chief Technology Officer, of 2ndQuadrant and PostgreSQL Major Developer/Committer:

 

Tell us about your commitment to the PostgreSQL Community.

The 2ndQuadrant vision is to be the bridge between the database needs of enterprise users and open source contributions to PostgreSQL. We have pursued a joint strategy of providing both working code (available now) and later submitting the features into core PostgreSQL. Over the past 15+ years, our team has widely contributed to the growth and development of the PostgreSQL project; partnering with customers to identify bottlenecks and then contribute towards enterprise features that address them in PostgreSQL, benefiting everyone that uses it. Besides contributing code, all members of the 2ndQuadrant team are very active in the community on an individual and local level, often helping to organize PUG events, conferences, and meetups.

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

Marco Nenciarini - located in Prato, Italy - has been a long time supporter and contributor of PostgreSQL. He is an active maintainer of PGDG’s APT repository, maintaining builds and binaries for PostgreSQL and associated tools & extensions, while contributing towards process improvement for sane builds. Marco is the lead developer for Barman, a backup manager and disaster recovery tool for enterprises with high business continuity requirements.  He is the current president of IT.PUG in Italy and a part of the organizing committee for PGDay.IT.

What features would you like to see in v11 and v12?

As PostgreSQL matures, so do the features that come with each release. In the next two release we’re most looking forward to improved Partitioning performance, the implementation of the MERGE SQL command, and procedures that allow server-side transactions.

Are there any features in development from 2ndQuadrant that the community should be looking forward to?

2ndQuadrant is working hard on the development of Bi-Directional Replication (BDR3), containing new architectural features and a wide and deep set of features.

In addition, we continuously work on features for scalability, performance, security and robustness.

What is the number one barrier you see to contributing to the Postgres community?

The Postgres community is one of the easiest communities to become a part of. With an open mindset all around and a common goal of growing open source PostgreSQL, the community is very accepting to anyone looking to learn, contribute, and better the Postgres ecosystem as a whole. Between the helpful tools on postgresql.org and the growing community, comprised of seasoned veterans and fresh faces, there is always helpful information to guide you.

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

PostgreSQL is the most popular database when it comes to new adoption. Even existing users of other databases are flocking towards PostgreSQL - and it’s not just to save money. PostgreSQL has been growing year on year and we’re attracting interest from the largest enterprises, as it is fully capable of securely supporting enterprise database systems. 

There is still competition out there, especially with the current fad of developer-focused NoSQL databases. But the community is big enough and strong enough to quickly adapt to changing times and push forwards. The members of the PostgreSQL community are passionate about their work and the growth of the project.

Tell us why you believe people should attend PostgresConf 2018 in April.

Community conferences expand your knowledge in different areas of the technology, describe practical use cases as well as give sneak previews into cutting edge technologies for future versions of PostgreSQL.

As part of the countdown to PostgresConf US 2019, learn more about the engaging content and our speakers for this year in our Speaker Spotlight Series.

 

Henrietta "Hettie" Dombrovskaya is a database researcher and developer with over 30 years of academic and industrial experience. She holds a Ph.D. in Computer Science from University of Saint Petersburg, Russia, where she taugh Database and Transaction Theory, as well as multiple database tuning classes for both beginners and advanced professionals.

 

Her professional experience includes consulting for a number of government projects, and providing Data services in the financial sector, manufacturing, and distribution. She is a co-author, with B. Novikov, of the book “System Tuning." As Associate Director of DB at Braviant Holdings, she is happy to have an opportunity to implement the results of her research in practice.

 

Hettie will be presenting a breakout session on Wednesday, March 20, on "Using FDW Like Never Before." Read what she has to say about Postgres and why to attend her session:

 

Why Postgres? Tell us about your involvement with the greater Postgres community.

I started to use Postgres by pure accident. I used to be a hard-core Oracle person, with 20 years of Oracle experience, and then I was offered a job at a company that was using Postgres. The year was 2010. I hadn't use Postgres since my student years and Stonebraker's version, so I reluctantly agreed -- thinking that it would be a very temporal job. But after a couple of months I found myself completely enchanted with Postgres, and decided to stay -- with Postgres as well as with the company.

 

 

For the past  several years I've being more active in promoting Postgres in different communities. My goal is to show the variety of ways Postgres can be used virtually anywhere, to promote Postgres among industries, developers and in academia. Since Dec 2016 I have led a Chicago PostgreSQL User Group, and I always make sure I have interesting speakers every month. Also, I am actively participating in the development and promotion of bitemporal framework in Postgres.

 

What features do you believe should be developed/improved and released in the next major upgrade?

 

I hope that bitemporal framework will be eventually implemented as a real extension. 

 

Why should attendees come to your talk at PostgresConf US 2019? What would you like for them to take away from your session?

 

I have two sessions at this conference. The first one, "Using FDW Like Never Before" is literally about "where there is a will, there is a way"! I am just showing a cool technique everyone can use, and hope somebody will build a Postgres feature on this idea.

 

The subject of the second session, ""Connecting Galaxies: Information Exchange Techniques for Java/PostgreSQL Applications" -- which I am co-presenting with Alyssa Ritchie -- is something I have been working on throughout my entire professional life. Most of the time when database people talk about optimization, they mean the SQL queries optimization. When we are talking about the real-life application -- not the abstract query -- the most performance gains can be achieved when optimizing the way an application interacts with a database.

 

This is one of the topics which "does not belong", and neither DB people, nor the application people want to claim it. So, once again, I am trying to profess and spread the word.

 

What advice would you have for a Computer Science graduate or entry level developer who are interested in learning and engaging with Postgres?

 

Revisit your freshman year math, calculus and algebra. You can't write good SQL without it.

Elizabeth Zalman is the Co-founder & CEO of strongDM, the definitive data security product. Previously she was Co-Founder and CEO of the cross-device profile company Media Armor.

Liz will be presenting a breakout session "Do You Know Your Vendor Dependencies" on Wednesday, April 18, at 4 pm. Read what she has to say about Postgres and why to attend her session: 

Why PostgreSQL? What got you into it, and made you stick with it?

Featureful performance & proven reliability. Over the years I've found fewer and fewer reasons to consider alternatives beyond Postgres (two notable exceptions being redis-style KV and queues).

Tell us about your involvement with the greater Postgres community.

strongDM hears a lot about how its customers use PG and its derivatives (Greenplum, the latest on Aurora, etc.) and we love sharing tips when appropriate.

What new features of PostgreSQL 10 are you most excited about?

As a security product, we're always happy to see security-related upgrades: SASL/SCRAM authentication is a popular option in several of database systems, and is a significant upgrade over the previous salted hashes. We also rely heavily on partitioning, so all related enhancements are welcome.Finally: although we generally wouldn't choose to run parallel queries in a primarily OLTP system, the promise of running analytic queries on a replica (rather than ETL'ing into an analytic database) is very appealing.

What features should be developed/improved and released in the next major upgrade?

Dynamic optimization for queries on partitioned tables. Right now if you run select * from date_partitioned_table where event_timestamp between NOW() and NOW() - interval '7 days'; It scans every partition because the result of NOW() is not knowable ahead of time. But it could optimize that query when it was asked to execute it. Instead of creating a static query plan it could say, I know I'm going to have to compute a list of partitions. So, let's just remember that. Then right before the query runs, it could calculate the list and run the query as though it had been planned with a static date range, and thus only query the affected tables. 

 Why should attendees come to your talk at PostgresConf US 2018?

In this talk, I'll share practical examples of breaches I've personally experienced along with advice on how to hold your vendors accountable, and hopefully make the topic of security a little less intimidating in the process.

What sessions are you most excited about attending at PostgresConf US 2018?

I am looking forward to attending “Reducing the Surface Area of Risk in Data Security” by Tim Gorman and “General Data Protection Regulation (GDPR) with Azure Database for PostgreSQL” by Mark Bolz.

What is your favorite aspect of PostgresConf US?

Being able to network with and learn from a unique community! I’ve found practice to really be one of the best ways to learn about databases.

 What advice would you have for a Computer Science graduate or entry level developer who are interested in learning and engaging with Postgres? 

 I’ve found practice to really be one of the best ways to learn about databases. Get your hands dirty: try breaking things and then fixing them!
