Running Elasticsearch at large scale - Alex Cercel - Percona Live Online 2020

ElasticSearch is a high-performance search engine based on Apache Lucene. It is growing in popularity which means that more and more users are running part of their search patterns against the information stored on this datastore. However, it’s quite difficult to find a comprehensive set of best practices that will assist in efficiently running large scale clusters. In this talk, I will cover tuning parameters and approaches that will help...

    Parallelism in PostgreSQL - Ibrar Ahmed - Percona Live Online 2020

    PostgreSQL’s architecture is process-based instead of thread-based. PostgreSQL launches a process “postmaster” on startup and after that spans a new process whenever a new client connects to PostgreSQL. Before version 10 there was no parallelism in a single connection. It is true that multiple queries from a different client can have parallelism because of process architecture, but a single query runs serially and did not have parallelism...

    Expert MariaDB: Utilise MariaDB Server Effectively - Colin Charles - Percona Live Online 2020

    Let's take a simple Oracle-backed application, and migrate it to MariaDB Server 10.4. While we are at it, let's learn about how to use system versioned tables, Galera 4, the MyRocks storage engine, Flashback to rollback tables/databases to an older snapshot, and also use the built-in thread pool. This and more is possible in 3 hours, as MariaDBServer 10.4 has been out for some time now (June 2019) and it has many new features, some of...

    Kubernetes - the Swiss Army Knife for your ProxySQL deployments - Rene Cannao - Percona Live 2020

    ProxySQL is a high performance proxy from design to implementation. It speaks the MySQL protocol, and can go beyond load balancing. This talk covers various deployment options for ProxySQL in a Kubernetes environment.
    Typically ProxySQL is deployed in one of three ways depending on the scale and needs of your environment:
    - Directly on each application server
    - On a separate server (or layer)
    - Cascaded, i.e. on each...

    Dark corners of the MySQL code base - Daniel Black - Percona Live Online 2020

    As you'd expect with a 25+ year code base there are aspects of the MySQL codebase that are unglamorous. These dark corners contain implementations that introduce behaviour that users depend upon, that changing will introduce storage or replication compatibility issues, or just don't attract the resources to sufficiently rewrite. These areas of code can lead to performance degradation by having code that doesn't utilize hardware in an...

    Unbounded scale: Using Vitess for scaling write intensive workloads - Percona Live Online 2020

    Unbounded scale: using Vitess for scaling write intensive workloads by Morgan Tocker, Daniel Guzman Burgos
    Scaling very large MySQL applications is the ultimate challenge, and there's no native solution for it. Since vertical scaling is not sustainable in time, horizontal scaling is the smartest move. Sharding issues within MySQL are not trivial but also not imposible. We will discuss thoses issues and how Vitess handle those to...
