YeSQL: Battling the NoSQL Hype Cycle with Postgres

December 3, 10:00 – 10:45 @ Track A

Abstract
Relational databases are regularly challenged by new technologies that promise to make SQL obsolete, but the new technologies often fade into obscurity. This talk explores how new NoSQL technologies are unique, and how existing relational database systems like Postgres are adapting to handle NoSQL workloads.

PostgreSQL Backups the modern way

December 3, 11:00 – 11:45 @ Track A

Abstract
There have been many different ways to take backups of PostgreSQL systems over the years, and the tools to do so have evolved both inside PostgreSQL and as addons. Are you using pg_dump for backups? Calling pg_start_backup()? Writing an archive_command? Then you’re probably missing out on new features, and possibly even risking your backups. In this talk we’ll go through the “right” way to do backups on modern versions of PostgreSQL, both using builtin tools and proven external utilities.

Beyond EXPLAIN: Query Optimization Behind the Scenes

December 3, 11:00 – 11:45 @ Track B

Abstract
EXPLAIN is too much explained. Let’s go “beyond EXPLAIN”.
This talk will take you to an optimizer backstage tour: from theoretical background of state-of-the-art query optimization to close look at current implementation of PostgreSQL. Experiences to hack the optimizer in our laboratory will also be shared.

Performance Improvements in PostgreSQL 9.5, 9.6 and beyond

December 3, 13:00 – 13:45 @ Track A

Abstract
Recent PostgreSQL releases bring plenty of new features, and a lot of them are related to performance – PostgreSQL 9.5 and 9.6 are not an exception – parallel queries, multiple improvements of sorting
performance, hashjoin improvements, lock scalability, optimizer improvements, etc. This talk aims to present the main performance improvements along with benchmarks illustrating the gains.

I also plan to briefly talk about what may happen in the near future – what performance-related features the community are in the works.

Pgpool-II: Past, Present and Future

December 3, 13:00 – 13:45 @ Track B

Abstract
Pgpool-II now has 13 years of history if counted from the first generation of the software, pgpool.
Pgpool was originally born aiming to add missing features to PostgreSQL, including connection pooling and replication.
It has been evolving to Pgpool-II with a growth of PostgreSQL, and now it is used by many users in all over the world.

In this talk we first present the history of evolution of Pgpool-II,
then explain available features of Pgpool-II and how we can use them in a production environment.

Finally we will give some ideas for the future of Pgpool-II.

PGroonga – Make PostgreSQL fast full text search platform for all languages!

December 3, 14:00 – 14:45 @ Track A

Abstract
PostgreSQL has built-in full text search feature. But it supports only limited languages. For example, it doesn’t
support Japanese. pg_trgm bundled in PostgreSQL supports all languages including Japanese. But it has performance problems for large documents.

This talk describes about PGroonga that resolves these problems.

Abstract
Review of progress on PostgreSQL technologies for logical replication using both pglogical and in-core replication, as well as their use for multi-master clustering in the Postgres-BDR project. We will also discuss Postgres-XL and other technologies.

What are the similarities and differences of using PostgreSQL between Japan and Europe?

December 3, 15:15 – 16:00 @ Track B

Abstract
Open source software have been developed by a lot of developers all over the world and it is said that the number of developers working in Europe is the second largest part in the world, just after the US. Although PostgreSQL is one of the open source software born in the US, many useful features and tools have been appeared by European developers and introduced in every PostgreSQL event. Moreover the number of case studies that PostgreSQL is used on the large-scaled systems has also been increasing in Europe.

I have realized that there were the technical information which had not come into Asia and Japan yet, and similarities and differences of using PostgreSQL between Japan and Europe, through joining the events held in the UK, Spain, Belgium and Austria since I started to work in the UK in spring 2014. I hope my presentation introducing them will be helpful to those people who use PostgreSQL and consider using it.
