The University of Washington’s Institute for Health Metrics and Evaluation (IHME) supports multiple research teams who contribute research and data towards the comprehensive Global Burden of Disease Study. As the volume of data rapidly grows throughout the tenure of the study, IHME has looked to various database platforms to meet their growing needs. Initially choosing Percona Enterprise Server 5.6, significant time and resources were invested into performance tuning the database environment to handle the query and data loading traffic from their 16,000 CPU-core high performance computer cluster. While the platform met initial needs, issues developed in being able to handle the increased volume of data and IHME needed to find a more reliable and flexible solution.

This talk will describe our journey to MariaDB, and will focus on:

  • Our initial needs and architecture demands

  • The growing pains and challenges

  • The ColumnStore solution

Sessions
Wednesday, April 12
2:10 pm - 3:00 pm

Clustering is an important feature in container technology, as multiple nodes are required to provide redundancy and failover in case of outage. Docker Swarm is an orchestration tool that allows administrators to manage a cluster of Docker nodes as one single virtual system. MariaDB Cluster, however, has its own clustering model based on Galera.

How do you get the two to work together? Container orchestration tools like Docker Engine swarm mode and Kubernetes are not aware of the redundancy model of MariaDB Cluster and presumes containers are independent from each other. It is possible, however, to make Swarm aware of Galera’s model by extending Galera on-container startup logic to bring MariaDB up to the correct state before serving any data.

In this talk, we’ll look at how to deploy MariaDB Cluster on Docker Swarm with a multi-host environment, by “homogeneousing” the MariaDB image to achieve high availability and scalability in a fully automated way. We will touch upon service controls, multi-host networking, persistent storage, scaling, fault tolerance, service discovery, and load distribution.

Sessions
Wednesday, April 12
1:10 pm - 2:00 pm

Data inconsistency is the worst problem that can happen for a synchronous database cluster. At some point it will appear during replication processing, simply because the application of replication events is not possible in some cluster nodes due to missing rows, excessive rows or wrong values in the row columns. As a result, this usually stops the replication process altogether or, at the least, the failing node must drop out from the cluster. Sorting out the reason for the cluster inconsistency can be problematic because the inconsistency may have occurred without leaving any signs in the system. Therefore, it may also be difficult to determine which cluster node has the trusted data contents.

Recovering from data inconsistency usually requires full database state transfers across the cluster nodes. Galera Cluster 3 has a strict inconsistency policy: all transaction replication errors cause emergency abort for all nodes detecting the inconsistency – a rather aggressive strategy that can lead to full cluster crash. Galera Cluster 4 has a more sophisticated inconsistency strategy where the cluster runs an inconsistency voting protocol and optimizes the way the cluster reacts to the detected inconsistency. This presentation will describe:

  • The various reasons that cause data inconsistency in a cluster

  • Possible ways to deal with them

  • How to recover a cluster after data inconsistency

  • Galera Cluster’s built-in support for continuous consistency checking, helping to harden the cluster against potential threats for data inconsistency

  • The difference in data inconsistency strategies between Galera 3 and Galera 4 clusters

Replication is a feature that is easy to set up, allows read-write access on both master and slave, and can easily create complicated deployments, such as circular replication. By default, MariaDB and MySQL replication is asymmetrical, but has a semi-sync replication plugin that supports multi-master slaves. All these features can be implemented quickly; however, there is also huge risk in making the wrong decisions. In this session, I will:

  • Discuss common replication errors and methods which will help to resolve them

  • Use built-in, then command-line tools, because knowledge of how they work is essential for effective troubleshooting

  • Cover the differences between MariaDB and MySQL replication

MariaDB supports online alter for many types of changes; however, some alters still require a table copy, and an online schema change tool is desired. The GitHub online schema change transmogrifer, gh-ost, is a new tool that I have already had the pleasure of using in production environments successfully. I will present a use case for running the tool in a complex multi-source, multi-slave replication topology to make changes unsupported by the native MariaDB online alter. This presentation will include a demonstration of the operational tools within gh-ost to throttle or view the status of the running alter process.

To be able to work with MariaDB ColumnStore, or with any other database, we need to get some data in it first. As ColumnStore is built on MariaDB, it may be presumed that loading data into ColumnStore is no different than with MariaDB. While this is possible, it is not the most efficient way. MariaDB ColumnStore is a column-based distributed database system, and while LOAD DATA INFILE and standard INSERT, UPDATE and DELETE statements work, there are faster and better ways to load data into ColumnStore. This talk will discuss how and from where to retrieve data, and will showcase examples, guidelines and demos for data loading with MariaDB ColumnStore.

With a focus on practical applications, this talk will give a full introduction to window functions, an important tool for analytical queries. Window functions act as regular functions but have access to more than one row during computation. This makes them highly useful for optimizing queries involving self-joins, as well as queries that need to extract data from multiple related rows from the same table. The performance speedups obtained are sometimes hundredfold, especially for analytical use cases. We will cover syntax, supported functions, use cases and performance. We will also see how MariaDB compares feature wise to other database solutions.

The velocity of change in today’s world, regarding new opportunities, as well as new threats, can only be handled by technology that is a reflection of our times. State sponsored cyberattacks on private companies, or operational leverage of machine learning, are just two examples of threats and opportunities that were unheard of five years ago. This duality is the new normal, and past methods of proprietary responses cannot continue. Accordingly, the world is moving. Only a well organized community of innovation can keep up. Therein lies the strategic mandate of Open Source. Michael Howard will illustrate the key points of this mandate, exemplified through innovation and how MariaDB is helping some of the largest organizations in the world into the era of Open Source.
