Webinar: MariaDB 10.11 key features overview for DBAs
Orgnised by Vettabase
27 April 2023
Amongst other topics:
- Long ALTER TABLES now don’t cause replicas to lag
- InnoDB configuration is now more dynamic, and certain important variables can be modified without a restart
- Populating an empty table is now much faster
- New data types: UUID, INET4, INET6
- SFORMAT() function, NATURAL_KEY_SORT() function
Abstract: A histogram represents the frequency of data distribution. This histogram can help in predicting a better execution plan. MariaDB and MySQL support HIstogram. Though they serve a common purpose they are implemented differently in MariaDB and MySQL, they have their control knobs. Our Consultants ( Monu Mahto and Madhavan ) articulate how histograms can be used in your production MySQL and MariaDB databases and how it helps in bringing down the execution time.
This tutorial covers all parallel replication implementation in MariaDB 10.0 and 10.1 and MySQL 5.6, 5.7 and 8.0 (including how it works in Group Replication).
MySQL and MariaDB have different types of parallel replication. In this tutorial, we present the different implementations that allow us to understand their limitations and tuning parameters. We cover how to make parallel replication faster and what to avoid for maximizing its benefits. We also present tests from Booking.com workloads.
Some of the subjects that are covered are group commit and optimistic parallel replication in MariaDB, the parallelism interval of MySQL and its Write Set optimization, and the ?slowing down the master to speed up the slave? optimization.
After this tutorial, you will know everything you need to implement and tune parallel replication in your environment. But more importantly, we will show how you can test parallel replication benefit in a non-disruptive way before deployment.

Similar to MariaDB AX: Analytics with MariaDB ColumnStore (20)
SkySQL is the first and only database-as-a-service (DBaaS) to perform workload analysis with advanced deep learning models, identifying and classifying discrete workload patterns so DBAs can better understand database workloads, identify anomalies and predict changes.
In this session, we’ll explain the concepts behind workload analysis and show how it can be used in the real world (and with sample real-world data) to improve database performance and efficiency by identifying key metrics and changes to cyclical patterns.
SkySQL uses best-of-breed software, and when it comes to metrics and monitoring that means Prometheus and Grafana. SkySQL Monitor is built on both, and provides customers with interactive dashboards for both real-time and historic metrics monitoring. In addition, it meets the same high availability and security requirements as other SkySQL components, ensuring metrics are always available and always secure.
In this session, we’ll explain how SkySQL Monitor works, walk through its dashboards and show how to monitor key metrics for performance and replication.
Introducing the R2DBC async Java connectorMariaDB plc
Not too long ago, a reactive variant of the JDBC driver was released, known as Reactive Relational Database Connectivity (R2DBC for short). While R2DBC started as an experiment to enable integration of SQL databases into systems that use reactive programming models, it now specifies a full-fledged service-provider interface that can be used to retrieve data from a target data source.
In this session, we’ll take a look at the new MariaDB R2DBC connector and examine the advantages of fully reactive, non-blocking development with MariaDB. And, of course, we’ll dive in and get a first-hand look at what it’s like to use the new connector with some live coding!
The capabilities and features of MariaDB Platform continue to expand, resulting in larger and more sophisticated production deployments – and the need for better tools. To provide DBAs with comprehensive, consolidating tooling, we created MariaDB Enterprise Tools: an easy-to-use, modular command-line interface for interacting with any part of MariaDB Platform.
In this session, we will provide a preview of the MariaDB Enterprise Client, walk through current and planned modules and discuss future plans for MariaDB Enterprise Tools – including SkySQL modules and the ability to create custom modules.
Faster, better, stronger: The new InnoDBMariaDB plc
For MariaDB Enterprise Server 10.5, the default transactional storage engine, InnoDB, has been significantly rewritten to improve the performance of writes and backups. Next, we removed a number of parameters to reduce unnecessary complexity, not only in terms of configuration but of the code itself. And finally, we improved crash recovery thanks to better consistency checks and we reduced memory consumption and file I/O thanks to an all new log record format.
In this session, we’ll walk through all of the improvements to InnoDB, and dive deep into the implementation to explain how these improvements help everything from configuration and performance to reliability and recovery.
SkySQL implements a groundbreaking, state-of-the-art architecture based on Kubernetes and ServiceNow, and with a strong emphasis on cloud security – using compartmentalization and indirect access to secure and protect customer databases.
In this session, we’ll walk through the architecture of SkySQL and discuss how MariaDB leverages an advanced Kubernetes operator and powerful ServiceNow configuration/workflow management to deploy and manage databases on cloud infrastructure.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

2. Agenda
• The Task - Analytics – Why and what
• The Requirements – What do we need for analytics
• The Solution – Column Based Storage
• The Product – MariaDB AX and MariaDB ColumnStore
• The Uses – MariaDB ColumnStore in action
7. Diagnostics: Why did it happen
• Aggregates: aggregate measure over one or
more dimension
– Find total sales
– Top five product ranked by sales
• Roll-ups: Aggregate at different levels of
dimension hierarchy
– given total sales by city, roll-up to get sales by
state
• Drill-down: Inverse of roll-ups
– given total sales by state, drill-down to get
total by city
• Slicing and Dicing:
– Equality and range selections on one or more
dimensions
8. Predictive: What is likely to happen
• Sales Prediction
– Analyze data to identify trends, spot
weakness or determine conditions
among broader data sets for making
decisions about the future
• Targeted marketing
– what is likelihood of a customer buying
a particular product based on past
buying behavior
10. Prescriptive: What is the best course of action?
Paradox of choices
With too many choices, which one is the best?
11. Big Data Analytics Use Cases
By industry
Finance
Identify trade patterns
Detect fraud and anomolies
Predict trading outcomes
Manufacturing
Simulations to improve design/yield
Detect production anomolies
Predict machine failures (sensor data)
Telecom
Behavioral analysis of customer calls
Network analysis (perf and reliability)
Healthcare
Find genetic profiles/matches
Analyze health vs spending
Predict viral oubreaks
13. What is an OLTP workload?
• OLTP applications are represents the most common database workload
• OLTP applications has a read / write ratio of maybe 50/50
– Web apps / E-commerce has more reads, ending with maybe 90/10
• OLTP applications deals with data on a row by row level
– Customer data, product data, order items etc.
– Single rows are selected, inserted, updated and deleted, one by one or in small groups
• OLTP data structures is somewhat of a representation of the business or the
applications that manage the data
– An order reference a customer, and order item is linked to an order
– Typically 3rd normal form or higher
– Sometimes individual aspects break the normal form, for performance reasons
• Transactions and ACID properties are required
14. The analytics workload
• Deals with data from a high level perspective
• Handles data in large groups of rows
– SELECTs data by date, customer location, product id etc.
– Data is loaded in batch or streamed in
– Data is mostly just INSERTed
• Dealing with individual data items is usually ineffective
• Data structures are optimized for analytics use and performance
• Data is sometimes purged, but just as often not
• Contains structured, semi-structured and sometimes unstructured data
• Data often comes from many different sources, internal and external
• Queries are ad-hoc, largely
• Transactions and ACID requirements are relaxed
15. Analytics database requirements
• Fast access to large amounts of data
• Scalable as data grows over time
– Analytics requirements increasing
– Regulatory requirements
– New data sources are added
• Load performance must be fast, scalable and predictable
• Data loading should be very flexible due to the different sources of data
– Some data loaded in batch, other is streamed
• Query performance also need to be scalable
• Data compression is a requirement
– Data size constraints, as well as read performance from disk
16. B-tree indexes
The good
B-tree indexes
The bad
• Well known technology
• Works with most types of data
• Scales reasonably well
• Really good for OLTP
transactional data
• Really bad for unbalanced data
• Index modifications can be really
slow
• Index modifications are largely single
threaded
• Slows down with the amount of data
• Really not scalable with large
amount of data
17. In summary, what do we need
• Something that can compress data A LOT
• Something that can be written to with fast and predictable performance
• Something that doesn't necessarily support transactions
– It doesn't hurt, but performance is so much more important
• Something that can support analytics queries
– Ad-hoc queries
– Aggregate queries
• Something that can scale as data grows
• Something that can still have a level of high availability
• Something that works with analytics tools, like Tableau, R etc.

20. To the rescue – Column Based Storage
• Data is stored column by column
• Each column is stored in one or more extents
– Each extent is represented by 1 file
• Each extent is arranged in fixed size blocks
• Extents are compressed (using Snappy)
• Data is one of
– Fixed size (1, 2, 4 or 8 bytes)
– Dictionary based with a fixed size pointer
• Meta data is in an extent map
– Extent map is in memory
– Extent map contains meta data on each
extent, like min and max values
Table
Column1 Column N
Extent 1
(8MB~64MB
8 million rows)
Extent N
(8MB~64MB
8 million rows)
21. To the rescue – Distributed data processing
• Clients connect to a User Module
• The User Module optimizes and
controls the execution
• Data is distributed among the
Performance Modules
• Data is stored, processed and
managed by Performance Modules
• Performance Modules process
query primitives in parallel
• The User Module combines the
results from the Performance
Modules
User Modules
