Percona is glad to announce the release of Percona Server5.5.37-35.0 on May 6th, 2014(Downloads are available here and from the Percona Software Repositories). Based on MySQL 5.5.37, including all the bug fixes in it, Percona Server 5.5.37-35.0 is now the current stable release in the 5.5 series. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.5.37-35.0 milestone at Launchpad.
New Features:
- Percona Servernow supportsMetrics for scalability measurement.
- Percona Servernow supportsAudit Log Plugin.
- Percona Serverpackages are now available forUbuntu14.04.
Bugs Fixed:
- Percona Servercouldn’t be built withBison3.0. Bug fixed#1262439, upstream#71250.
- Backported the upstream fix for overflow which would caused replication SQL thread to fail to execute events. Bug fixed#1070255(upstream#67352).
- Percona Serverdebug packages were not built for the previous releases. Bug fixed#1298352.
- Queries that no longer exceed
long_query_timewere written to the slow query log if they matched the previouslong_query_timevalue whenslow_query_log_use_global_controlvariable was set toall. Bug fixed#1016991. - When writing audit plugins it was not possible to get notifications for general-log events without enabling the general-log. Bug fixed#1182535(upstream#60782).
-
mysqld_safedid not correctly parseflush_cachesandnuma_interleaveoptions. Bug fixed#1231110. - Thread Poolwould handle a new client connection without notifying Audit Plugin. Bug fixed#1282008.
- Fixed a performance issue in extending tablespaces if running under fusionIO withatomic writesenabled. Bug fixed#1286114(Jan Lindström).
- Previous implementation of thelog_slow_rate_typeset to query withlog_slow_rate_limitfeature would log every nth query deterministically instead of each query having a 1/n probability to get logged. Fixed by randomly selecting the queries to be logged instead of logging every nth query. Bug fixed#1287650.
- Percona Serversource files were referencingMaatkitinstead ofPercona Toolkit. Bug fixed#1174779.
- Maximum allowed value forlog_slow_rate_limitwas
ULONG_MAX(ie. eitheror, depending on the platform). As it was unreasonable to configure the slow log for every four billionth session/query, new maximum allowed value is set to. Bug fixed#1290714.
Other bugs fixed:#1272732.

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AMInnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
MySQL vs. Other Programming Languages: A ComparisonApr 19, 2025 am 12:22 AMCompared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.
Learning MySQL: A Step-by-Step Guide for New UsersApr 19, 2025 am 12:19 AMMySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.
MySQL: Essential Skills for Beginners to MasterApr 18, 2025 am 12:24 AMMySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.
MySQL: Structured Data and Relational DatabasesApr 18, 2025 am 12:22 AMMySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.
MySQL: Key Features and Capabilities ExplainedApr 18, 2025 am 12:17 AMMySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.
The Purpose of SQL: Interacting with MySQL DatabasesApr 18, 2025 am 12:12 AMSQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.
MySQL for Beginners: Getting Started with Database ManagementApr 18, 2025 am 12:10 AMThe basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
