Digital Rights and Privacy: Concerns for the 21st century--by Andres Arrieta

The Electronic Frontier Foundation has been protecting and fighting for our civil liberties for over 30 years. In those 30 years a lot has happened: Our relationship to the internet has fundamentally changed, and yet, in many ways, our understanding of how it works has remained stagnant. 30 years ago, the Internet was a mystical place of wizardry with many unknowns, and a realm which was difficult to access. Today it’s a core part of our life that we have become reliant on, and while it has become far easier than ever to access the many gifts that the Internet provides, understanding of how it works - from policy makers to enforcement agencies - continues to lag. During that time, EFF and its mission have grown to cover many of the aspects that technology has brought for better or worse and to help protect those impacted by it, while ensuring a bright future with innovation that improves our lives. So what is happening today and where are our efforts going? Why have some issues like privacy and competition become so strongly intertwined, and what new opportunities and threats lay ahead? I’ll walk you through some of our work, some of the areas of concern, and some of the things I believe will help us work towards a better future.

Past, Present, and Future of Logical Replication--by Amit Kapila In this talk, I will tell how the Logical Replication has been evolved over years in PostgreSQL. This will explain some of the major recent enhancements like facilitating logical replication of two-phase and large in-progress transactions. I will share my views on how this technology can be leveraged to build a highly scalable and available database solution for large Enterprises. After that, I will also talk about some of the important enhancements being discussed in this technology area for future releases of PostgreSQL. I'll also cover how this technology can be enhanced for data migration from PostgreSQL to other databases.

IvorySQL--An Open Source Oracle-compatible Database Based on PostgreSQL--by GRANT ZHOU There are many users who need to migrate their applications from Oracle to the open source Postgres, but in order to support the new database, users often need to re-develop the application, which is inconvenient. If there is a database based on Postgres and compatible with most Oracle syntax and functions, it will be too convenient for customers. However, the official Postgres project will not accept this kind of code submission. After all, Postgres is Postgres, and Oracle is Oracle. So, let's make an Oracle compatible database. This talk will introduce how to make a database compatible with Oracle syntax based on PG, and introduce the IvorySQL project. This project is an open source project (Apache 2.0) led by Highgo Software, and currently has released version 1.2 based on PostgreSQL 14.2. Welcome everyone to contribute on this open source Oracle compatible database - IvorySQL, powered by PostgreSQL.

Non-Relational Postgres--by Bruce Momjian Postgres has always had strong support for relational storage. However, there are many cases where relational storage is either inefficient or overly restrictive. This talk shows the many ways that Postgres has expanded to support non-relational storage, specifically the ability to store and index multiple values, even unrelated ones, in a single database field. Such storage allows for greater efficiency and access simplicity, and can also avoid the negatives of entity-attribute-value (eav) storage. The talk will cover many examples of multiple-value-per-field storage, including arrays, range types, geometry, full text search, xml, json, and records.

Using Global database in Amazon Aurora PostgreSQL--by Shayon Sanyal and Sukhpreet Bedi An Amazon Aurora Global database is designed for globally distributed applications, allowing a single Amazon Aurora database to span multiple AWS Regions. It replicates your data with no impact on database performance, enables fast local reads with low latency in each Region, and provides disaster recovery (DR) from Region-wide outages. In this session, learn how to plan for cross-Region DR and easily scale Aurora reads across the world to place your applications close to your users. You also learn how to meet your recovery point objective (RPO) and recovery time objective (RTO) with Amazon Aurora global databases.

Amazon Babelfish for Aurora--by chandra pathivada Now the Babelfish for Aurora is available. This presentation is about how Babelfish helps customers to migrate SQL Server workloads to Postgres. In this presentation, we are going to give a demo of what is Babelfish , the internals of Aurora ,Aurora for SQL Server DBAs using Babelfish, and Labs on Application Migration.

The Biography of a Modern Cloud Native Application--by Alexandra Elchinoff and Karthik Ranganathan Modern cloud native applications lead exciting lives - from their birth in the cloud and dealing with massive unplanned success to surviving cloud outages and handling customers worldwide. In this talk, Yugabyte CTO Karthik Ranganathan walks through the eventful life of a successful cloud native app, as seen from the perspective of the data layer.

Hi guys, PostgresWorld Webinars is back!

PostgreSQL plays an important role in the development of databases in China. Many database products around the world choose PostgreSQL as their technology development path. However, the problem of migrating applications from Oracle to Open source Postgres became the biggest obstacle, so we created the IvorySQL open source project, which is based on the latest PostgreSQL 14 database with strong Oracle compatibility. But why do we have to do IvorySQL open source project? How is it technically different from Postgres and Oracle? This webinar invites you to join us.

This webinar is hosted by Grant Zhou on IvorySQL - An Open Source Oracle-compatible Database Based on PostgreSQL.

Guest introduction

Grant Zhou currently lived in Canada, he is the founder of Highgo Software North America, and he is leading the company PostgreSQL development team with members from Canada, China and Pakistan. He is working as the secretary of the International Consultant Committee of the PostgreSQL China Association at the same time, and also proud to be the Organizer & Asia Liaison at PostgresConf. He worked in Alcatel-Lucent (Nokia) company for more than ten years and had rich experiences on high availability, real-time telecommunication systems, database technologies and Unix/Linux programming.

In December 2021, the team announced the first available version of IvorySQL database, which is the only open source database with Oracle compatibility features based on PostgreSQL. On Feburay 28, 2022, based on PostgreSQL 14.2, IvorySQL 1.2 was released.

Conference Highlights

There are many users who need to migrate their applications from Oracle to the open source Postgres, but in order to support the new database, users often need to re-develop the application, which is inconvenient. If there is a database based on Postgres and compatible with most Oracle syntax and functions, it will be too convenient for customers.

Hello

Just when the world was packing the bags for the holiday season and getting ready to welcome the New year we were hard at work and were giving the final touches to the project that our team was working on since the start of 2021. And it was the 15th of December just before the day end we got all green lights and silently released the very first version of IvorySQL before cleaning up the desk for that day.

IvorySQL at Glance

IvorySQL is Apache 2.0 licensed Open Source Oracle compatible PostgreSQL. The very first release of IvorySQL is derived from PostgreSQL 14 with a firm commitment to always remain 100% compatible and a Drop-in replacement of the latest PostgreSQL.

IvorySQL adds a compatible_db GUC on top of existing standard PostgreSQL configuration parameters. The compatible_db is a toggle switch to switch between Oracle and PostgreSQL compatibility modes. The second major highlight of IvorySQL is PL/iSQL procedural language that supports oracle’s PL/SQL syntax. These two additions sit at the core of Oracle compatibility of IvorySQL without breaking the standard PostgreSQL compatibility. The compatible_db switches the behavior of functions and objects that exist in both Oracle and PostgreSQL and acts differently, while PL/iSQL builds the foundation for running the oracle code on IvorySQL with minimal changes.

IvorySQL comes with numerous Oracle compatibility features including Oracle style PACKAGES, DATA Types, and Conversion Functions. For details of Oracle compatibility features in IvorySQL refer to IvorySQL documentation

We are committed to following the principles of open source way

IvorySQL is committed to abiding by the principles of open-source ways and we strongly believe in building a healthy and inclusive community. We maintain that good ideas can come from anywhere, and the best ideas should win. Only by including diverse perspectives, we can reach to the best decision. While the first version of IvorySQL is mainly focused on Oracle Compatibility features, going forward the future road map and feature set will be determined by the community in an open-source way.

Contributing to the IvorySQL

There are plenty of ways to contribute to IvorySQL. You can contribute by providing the documentation updates, by providing the translations for the documentation. If you have design skills you can contribute to the IvorySQL website project.
Testing the IvorySQL and reporting issues, by issuing pull requests for bug fixes or new features or answering the questions on mailing lists are some ways to contribute to the IvorySQL project and all types of contributions are welcomed and appreciated by the IvorySQL community.

Getting Started

All IvorySQL related projects including database server, website, and documentation are hosted and managed through Github. You can download the source code or released packages and track the current issues, pull requests, and discussions through the IvorySQL Github page.
