This document discusses MySQL partitioning, including when and why to use partitioning, different types of partitioning, and how to manage partitions. It covers using partitioning for faster deletion of data by dropping partitions, faster queries through partition pruning, and making some operations like adding indexes faster by performing them on individual partitions rather than entire tables. It provides examples and best practices for using partitioning for both short and long term rolling of data.
Let's get into several common types of queries that developers struggle with, showing SQL solutions, and then analyze them for optimal efficiency. I'll cover Exclusion Join, Random Selection, Greatest-Per-Group, Dynamic Pivot, and Relational Division.
Advanced MySQL Query Tuning - talk at Percona Live and MySQL Meetup tour.
Tuning Queries and Schema/Indexes can significantly increase performance of your application and decrease response times.
This year I will cover new MySQL 5.6 and 5.7 algorithms that has been designed to improve query performance and simply tuning.
Topics:
1. Group by and order by optimizations
2. MySQL temporary tables and filesort
3. Using covered indexes to optimize your queries
4. Loose and tight index scan in MySQL
5. Using summary tables to optimize your reporting queries
6. New MySQL 5.6 and 5.7 Optimizer features and improvements
Adrian Hardy's slides from PHPNW08
Once you have your query returning the correct results, speed becomes an important factor. Speed can either be an issue from the outset, or can creep in as your dataset grows. Understanding the EXPLAIN command is essential to helping you solve and even anticipate slow queries.

MySQL users commonly ask: Here's my table, what indexes do I need? Why aren't my indexes helping me? Don't indexes cause overhead? This talk gives you some practical answers, with a step by step method for finding the queries you need to optimize, and choosing the best indexes for them.
The JSON data type and functions that support it comprise one of the most interesting features introduced in MySQL 5.7 for application developers. But no feature is a Golden Hammer. We need to apply a little expertise to get the best of it, and avoid misusing it. I’ll show practical examples that work well with JSON, and other scenarios where conventional columns would perform better. Questions addressed in this presentation: How much space does JSON data use, compared to conventional data? What is the performance of querying JSON vs. conventional data? How do I create indexes for JSON data? What kind of data is best to store in JSON? How do I get the best of both worlds?
Required for certification, window functions are powerful analytic functions built into SQL Server. SQL Server 2005 introduced the core window ranking functions, and SQL Server 2012 added time and statistical percentage window functions. These functions allow for advanced variable creation, and are of direct benefit to people creating features for data science. This talk will also recommend further reading on this topic.
Hibernate ORM: Tips, Tricks, and Performance TechniquesBrett Meyer
DevNexus 2014
Out-of-the-box, Hibernate ORM offers limited overhead and decent throughput. Early-stage applications enjoy the convenience of ORM/JPA with great performance. However, scaling your application into an enterprise-level system introduces more demanding needs.
This talk will describe numerous tips and techniques to both increase Hibernate ORM performance, as well as decrease overhead. These include some basic tricks, such as mapping and fetching strategies. Entity enhancement instrumentation, third-party second level caching, Hibernate Search, and more complex considerations will also be discussed. The talk will include live demonstrations techniques and their before-and-after results.

Query Optimization with MySQL 5.6: Old and New Tricks - Percona Live London 2013Jaime Crespo
Tutorial delivered at Percona MySQL Conference Live London 2013.
It doesn't matter what new SSD technologies appear, or what are the latest breakthroughs in flushing algorithms: the number one cause for MySQL applications being slow is poor execution plan of SQL queries. While the latest GA version provided a huge amount of transparent optimizations -specially for JOINS and subqueries- it is still the developer's responsibility to take advantage of all new MySQL 5.6 features.
In this tutorial we will propose the attendants a sample PHP application with bad response time. Through practical examples, we will suggest step-by-step strategies to improve its performance, including:
* Checking MySQL & InnoDB configuration
* Internal (performance_schema) and external tools for profiling (pt-query-digest)
* New EXPLAIN tools
* Simple and multiple column indexing
* Covering index technique
* Index condition pushdown
* Batch key access
* Subquery optimization
How to Analyze and Tune MySQL Queries for Better Performanceoysteing
Tutorial at Oracle Open World 2015:
Performance of SQL queries plays a big role in application performance. If some queries execute slowly, these queries or the database schema may need tuning. This tutorial covers query processing, optimization methods, and how the MySQL optimizer chooses a specific plan to execute SQL. See demonstrations on how to use tools such as EXPLAIN (including the JSON-based variant), optimizer trace, and performance schema to analyze query plans. See how the Visual Explain functionality in MySQL Workbench helps you to visualize these plans. Based on the analysis, the tutorial covers how to take the next steps for performance tuning. It might mean forcing a particular index, changing the schema, or modifying configuration parameters.
Postgres Plus Advanced Server 9.4 gives database administrators greater control and expanded options for customization that boost performance and simplify many common tasks. Among the new features in the release are resource management and compatibility for an expanded set of Oracle functions and applications that boost performance and support developers. The release also features JSONB and other advances in the open source community PostgreSQL for supporting applications with unstructured data, eliminating the need for a standalone NoSQL-only solution.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
