PostgreSQL universal database
12/05 10:10 – 10:55
– Abstract –
The objective of my talk is to show the future of PostgreSQL as a Universal Database. By now, PostgreSQL has gained considerable popularity not only in the open source community, but also with big corporate users. There are several factors for this change, and one of them is the disclosure of development roadmaps published by major Postgres-centric companies. These companies employ PostgreSQL contributors, who implement user-demanded features. Even if implemented in proprietary forks, these features are eventually returned to the open-source community. To be commercially successful, Postgres companies have to compete with other databases available in the market today. Some of them are traditional relational databases, whereas others are specialized, niche databases focused on new emerging applications. The key feature of the original Postgres design is its extensibility. I am a proponent of the idea that PostgreSQL should improve and apply its extensibility to fill many niches, such as web, fintech, blockchain, etc. Therefore, I see the future of PostgreSQL as a Universal Database working with a very wide range of applications in the future world. NoSQL Postgres is one example of how PostgreSQL provides unique combination of rich functionality of powerful relational database and flexibility of nosql systems.

PostgreSQL Strengthen Our Country
12/05 10:55 – 11:40
– Abstract –
PostgreSQL has been around since 2010 in Indonesia, starts that year we have more and more evidence of Implementation PostgreSQL in replace (usually) Commercial Proprietary Databases such as Oracle. With its high capacity, high availability, and high performance. Right now many banks including BCA and Mandiri (the two biggestbank in Indonesia)It is a great opportunity for such of Open Source Product like PostgreSQL being used in many implementations especially in Financial Industries in Indonesia. Some of the great achievement from us is: Migration 10.000 LoC, 659 Tables from 3 Sparc Server Oracle into a single Intel Server on PostgreSQL, and runs stable in production level. The Launching of PostgreSQL 10 in Indonesia has covered by close to 20 News mediaincluding Printed media as well. This is very great since we never had this such phenomenal acceptance before. Indonesia Business Society has ready to adopt more PostgreSQL even deeper and greater. Indonesia needs Open Source, to strengthen our economy, to save capital, to ensure data Integrity and security.

Eliminating PostgreSQL 19% cache-misses and 6% clock cycles by using GCC optimizations
12/05 13:00 – 13:40 @ Track B
– Abstract –
This talk provides qualitative insights into PostgreSQL source code structure for people who want to enhance its performance. We will present an in-depth observation of instruction-per-cycles, cache misses, and memory consumption of each function in PostgreSQL. The profiling result shows performance bottlenecks have repeating patterns. Take SnapshotData for example. In most cases, the value of condition variables of GetTransactionSnapshot function are identical. If we know the value of these variables, then we can simplify conditions of the control flow, and get further performance improvement. We use this concept and leverage GCC’s two optimizations – clone function optimization and variable range propagation – to eliminate 6% clock cycles and reduce 19% cache-misses dramatically.

Postgres as BI platform for largest Irish pharmacy supplier’s chain, our experience and errors
12/05 13:50 – 14:30 @ Track A
– Abstract –
I will talk about our BI application which we built on Postgres for largest Irish pharmacy supplier’s chain. We will review business requirements shortly. Later on I will describe specific of our architecture, why we chose snowflake scheme and how we are doing extract, transformation and load procedures. It will be mentioned about special Postgres tuning for OLAP and massive data bulk load workloads. Also I will let you know about Postgres usage as a column database with cstore_fdw by Citus and results achieved. Cons and problems of our approach will be described in the end of the talk.

Road to a multi-model database: making PostgreSQL the most popular and versatile database
12/05 13:50 – 14:30 @ Track B
– Abstract –
More and more applications are using diverse data models other than the relational model to represent various things in the real world digitally.
In order for PostgreSQL to respond to more needs and prosper, it is essential to be able to handle those data models.
In this session, I will give insight into what PostgreSQL should aim for as a multi-model database.

NoSQL Best Practices for PostgreSQL
12/05 15:30 – 16:10 @ Track A
– Abstract –
Everyone already knows the Jsonb data type: one of PostgreSQL’s most attractive features which allows efficient work with semi-structured data without sacrificing strong consistency and ability to use all the power of proven relational technology. But what exactly is inside Jsonb, are there any caveats, and how can you accidentally bring down performance?
We will discuss all that questions altogether with advantages and disadvantages of using Jsonb in different situations in comparison with other solutions and existing standards. I’ll show some important best practices about how to write compact queries to work with Jsonb and avoid common mistakes/performance problems.
