MySQL 5.7 NEW FEATURES, BETTER PERFORMANCE, AND THINGS THAT WILL BREAK -- Mid...Dave Stokes
MySQL is on the way and this presentation covers the new features, improved performance, and better admin that will come with 5.7. But there are some things that are changing that you need to know before you upgrade
MySQL 5.7 introduced native support for JSON data with a new JSON data type and JSON functions. The JSON type allows efficient storage and access of JSON documents compared to traditional text storage. JSON functions allow querying and manipulating JSON data through operations like extraction, search, and generation of JSON values. Developers now have more flexibility to work with hierarchical and unstructured data directly in MySQL.
The document outlines 10 usability guidelines for MySQL:
1) All features should be possible through SQL for consistency and discoverability.
2) Features, configurations, and errors should be intuitively obvious and discoverable without reading manuals cover-to-cover.
3) Too many similar configuration options without clear use cases can be paralyzing; only add options if use cases are known.
4) New configuration options must allow the effect to be measured through observability.
5) Features should work consistently across contexts for orthogonality.
6) The system should be safe to script against and avoid duplicate processing.
7) Extend functionality to match common use cases.
8) Preserve the ability to
This document summarizes a presentation about new features and changes coming in MySQL 5.7. Key points include: MySQL 5.7 will include performance improvements, more robust transaction handling and memory instrumentation.

Scaling MySQl 1 to N Servers -- Los Angelese MySQL User Group Feb 2014Dave Stokes
The document discusses various options for scaling MySQL databases to handle increasing load. It begins with simple options like upgrading MySQL versions, adding caching layers, and read/write splitting. More complex and reliable options include using MySQL replication, cloud hosting, MySQL Cluster, and columnar storage engines. Scaling to very large "big data" workloads may involve using NoSQL technologies, Hadoop, and data partitioning/sharding. The key challenges discussed are defining business and technical requirements, planning for high availability, and managing increased complexity.
Some internal tools were relying on deprecated statements and behavior that changed in MySQL 5.6.

Linux con europe_2014_full_system_rollback_btrfs_snapper_0sprdd
This document discusses using Btrfs and Snapper to enable full system rollbacks. It describes how snapshots are used to capture the state of the system at different points in time. These snapshots can then be used to rollback the entire system to a previous known good state, reducing downtime from system issues or configuration changes. The key capabilities of Snapshots include automatically capturing changes, displaying differences between snapshots, and rolling back to previous states. Integration with tools like YaST allow visualizing and undoing changes at the file level, while full system rollback supports reverting the entire operating system, including the kernel.

DataOps Barcelona - MySQL HA so easy... that's insane !Frederic Descamps
1. MySQL 8.0 InnoDB Cluster is a new high availability and scaling solution for MySQL that makes setup easy.
2. It uses Group Replication under the hood to allow writing to all nodes simultaneously while maintaining consistency.
3. Key components include MySQL Router for routing and load balancing, and MySQL Shell for administration.
MySQL Cluster is a proven technology that today is successfully servicing the most performance-intensive workloads. MySQL Cluster is deployed across telecom networks and is powering mission-critical web applications.
Without trading off use of commodity hardware, transactional consistency and use of complex queries, MySQL Cluster provides:
- Web Scalability (web-scale performance on both reads and writes)
- Carrier Grade Availability (99.999%)
- Developer Agility (freedom to use SQL or NoSQL access methods)
MySQL Cluster is recommended in the situations where:
- It is crucial to reduce service downtime, because this produces a heavy impact on business
- Sharding the database to scale write performance highly impacts development of application (in MySQL Cluster the sharding is automatic and transparent to the application)
- There are real-time responses needs
- There are unpredictable scalability demands
- It is important to have data-access flexibility (SQL & NoSQL)
From a practical point of view the HOL's steps were:
- Installation of MySQL Cluster
- Start & Monitoring of MySQL Cluster
- Connecting to MySQL Cluster
- Overview of MySQL Cluster’s Admin Commands & Operations

Test Polarity: Detecting Positive and Negative Tests (FSE 2024)andrehoraa
Positive tests (aka, happy path tests) cover the expected behavior of the program, while negative tests (aka, unhappy path tests) check the unexpected behavior. Ideally, test suites should have both positive and negative tests to better protect against regressions. In practice, unfortunately, we cannot easily identify whether a test is positive or negative. A better understanding of whether a test suite is more positive or negative is fundamental to assessing the overall test suite capability in testing expected and unexpected behaviors. In this paper, we propose test polarity, an automated approach to detect positive and negative tests. Our approach runs/monitors the test suite and collects runtime data about the application execution to classify the test methods as positive or negative. In a first evaluation, test polarity correctly classified 117 tests as as positive or negative. Finally, we provide a preliminary empirical study to analyze the test polarity of 2,054 test methods from 12 real-world test suites of the Python Standard Library. We find that most of the analyzed test methods are negative (88%) and a minority is positive (12%). However, there is a large variation per project: while some libraries have an equivalent number of positive and negative tests, others have mostly negative ones.
