Presented at the JSFoo conference for the first time.

The slides are uploaded here https://www.slideshare.net/SanjayManwani/mysql-8-loves-javascript via @SlideShare

Quick impression on the conference:

1. Very buzzy you could see the high energy levels.  Lots to learn about javascript and the speakers were also enthusiastic to speak. 700 attendees.

2. The focus was spot on. Security is something that everyone is worried about.

3. Staff was always on the spot and helpful. The organization looked great with the big video boards announcing the next talk etc.

4. It was also informal communication between the speakers with there being a whatsapp group for speaker to interact with one another.

5. A few things that I did point out to organizers e.g. the banners on the road outside were …

It’s almost here! One week until the Percona Live Europe Open Source Database Conference 2018 in Frankfurt, Germany! Are you ready?

This year’s theme is “Connect. Accelerate. Innovate.” We want to live these words by making sure that the conference allows you to connect with others in the open source community, accelerate your ideas and solutions and innovate when you get back to your projects and companies.

• There is one day of tutorials (Monday) and two days of sessions (Tuesday and Wednesday). We have multiple tracks: MySQL 8.0, Using MySQL, MongoDB, PostgreSQL, …

With new MySQL Shell 8.0.13 comes a new way to quickly load JSON data sets very quickly.  In a past blog and in several talks I have shown how to use the shell with the Python mode to pull in the data.  But now there is a much faster way to load JSON

Load JSON Quickly Start a copy of the new shell with mysqlsh. Connect to your favorite server \c dave@localhost and then create a new schema session.createSchema('bulk'). Then point you session to the schema just created with \use bulk.  Version 8.0.13 has a new utility function named importJson that does the work.  The first argument is the path to the data set (here the MongoDB restaurant collection) and the second allows you to designate the schema and collection where you wish to have the data stored.  In this example the data set was in the downloads directory of my laptop and I wanted to put it in the newly created 'bulk' schema …

What excites me is the possibility that this tool is giving to other people. Also, the challenges I’ve faced and the new ideas for the future releases are always source of interest that keep me focused on the project. So I’m looking forward to sharing this with the conference delegates.

pg_chameleon can achieve two tasks in a very simple way. It can setup a permanent replica between MySQL and PostgreSQL, giving the freedom of choice for the right tool for the right job, or can migrate multiple schemas to a PostgreSQL database.

Anybody that want to extend their database experience, taking the best of the two worlds, or who is seeking a simple way to migrate data with minimal downtime will find the presentation interesting.

What else am I looking forward to at Percona Live Europe?

I’m …

There’s just over one week to go so it’s time to announce the keynote addresses for Percona Live Europe 2018! We’re excited to share our lineup of conference keynotes, featuring talks from Paddy Power Betfair, Amazon Web Services, Facebook, PingCap and more!

The speakers will address the current status of key open source database projects MySQL®, PostgreSQL, MongoDB®, and MariaDB®. They’ll be sharing with you how organizations are shifting from a single use database to a …

MySQL Shell is a command-line shell for MySQL Server that has the capability for
interactive and batch code execution.  It also offers a wealth of APIs that make it easier and more efficient to work with and manage MySQL servers. In 8.0.13, we made an effort to make those APIs easily accessible straight from the command line.…

Containers are eating the world. If you have built and deployed an application in production over the last few years, the odds are that you have deployed your code in containers. You might have created and deployed individual containers (Docker, Linux LXC, etc.) directly in the beginning, but quickly switched over to a container orchestration technology like Kubernetes (K8s) or Swarm when you needed to coordinate multi-node deployments and high availability (HA). In this container-driven world, what will the future of the application stack look like? Let’s start with what we need from this “future” application stack.

What Do We Need From This Future Application Stack?

Enterprises require high availability for their business-critical applications. Even the smallest unplanned outage or even a planned maintenance operation can cause lost sales, productivity, and erode customer confidence. Additionally, updating and retrieving data needs to be robust to keep up with user demand.

Let’s take a look at how Tungsten Clustering helps enterprises keep their data available and globally scalable, and compare it to Amazon’s RDS running MySQL (RDS/MySQL).

Replicas and Failover What does RDS do?

Having multiple copies of a database is ideal for high availability. RDS/MySQL approaches this with “Multi-AZ” deployments. The term “Multi-AZ” here is a bit confusing, as enabling this simply means a single “failover replica” will be created in a different availability zone from the primary database instance. …

Without our sponsors, it would be almost out of reach to deliver a conference of the size and format  that everyone has come to expect from Percona Live. As well as financial support, our sponsors contribute massively by supporting their teams in presenting at the conference, and adding to the quality and atmosphere of the event. Having their support means we can present excellent in-depth technical content for the tutorials and talks, and that’s highly valued by conference delegates. This year, too, Amazon Web Services (AWS) sponsors the cloud track on day two, with a superb line up of cloud content.

Here’s a shout out to our sponsors, you’ll find more information on the Percona Live sponsors page:
