Keynotes Day 2 – Open Source Database Technology

In this video, you can find the Percona Live 2021, keynotes for Day 2, May 13rd, 2021. Kaj Arnö, MariaDB Foundation CEO, presents Collaboration in Open Source: A Jungle That Needs Structure. OpenSource is more than software, and contributions don’t just happen at the code level. Open Source is a development model and a mentality, which differs from legacy, closed, commercial models. Sure, the code is open, but so is communication and collaboration. Or rather, so they should be. Open collaboration is easier said than done, but it’s a key aspect of the overall usability and productivity of Open Source software usage. With MariaDB as the case in point, we look at the use of open tools to collaborate within the community of developers using MariaDB Server. What is the right way to report bugs and request features (over Jira, in our case)? And using and improving documentation (over Knowledgebase, for MariaDB)? Yes, Github hosts the MariaDB source code, but doesn’t it overlap with Jira? How do you get to chat with the fellow developers (over Zulip, in our case)? What is the proper use of blogs? Of Youtube videos? Of conferences? Of Stack Overflow and other tools? MariaDB does not claim to sit in with the perfect Open Source development and collaboration model. But we have put thought into it. This presentation hopefully provides the audience new ideas to structure their own communication, and gives MariaDB improvement ideas for its own processes. Frédéric Descamps, MySQL Community Manager, Oracle, presents State of the Dolphin Frederic will talk about the latest improvements in MySQL 8.0, MySQL 8.0.24 is just out! He will talk about MySQL Engineering Team’s steady progress with MySQL 8.0. These include solutions like Document Store, InnoDB Cluster, and InnoDB ReplicaSet where MySQL Router and MySQL Shell are playing an important role and of course what we have been busy with in the past 6 months. Fred will also announce something new developed by the MySQL Team. And of course, all of these Oracle solutions are completely OpenSource. Patrick McFadin, VP Developer Relations, Datastax, presents Database Administrators, Your Skills Are Needed in the Cloud-Native Future. As a database administrator, you have been in the middle of some amazing stories of scale and digital transformation. Now our industry is moving quickly into cloud-native architectures and the need for skills to get there has never been greater. The role of Site Reliability Engineer(SRE) is one of the fastest-growing job fields in IT and DBAs have the right combination of background and skills to make the transition. I’m here to make the case. Time to make the move from DBA to SRE. Dor Laor, ScyllaDB CEO, presents, ScyllaDB, Beyond Cassandra. The ScyllaDB team began a journey of implementing a better, C++ version of Cassandra with the same API and a promise of 10x the performance more than 6 years ago. Finally, in 2020 the mission of a complete, battle-tested API was done and we even added a compatible DynamoDB API. All along the team improved not just the performance but other aspects, from shard-aware drivers, heat-based load balancing, and seedless nodes. We’re proud of the result, but our work is far from done. This year, we introduce Raft which allows us to leap beyond the eventual consistency nature of Cassandra. The talk will cover the reasons for the introduction of Raft and how Raft comes into play with regard to consistency, elasticity, and ease of operation of Scylla.
