Optimizing MariaDB for maximum performanceMariaDB plc
When it comes to optimizing the performance of a database, DBAs have to look at everything from the OS to the network. In this session, MariaDB Enterprise Architect Manjot Singh shares best practices for getting the most out of MariaDB. He highlights recommended OS settings, important configuration and tuning parameters, options for improving replication and clustering performance and features such as query result caching.
The presentation covers improvements made to the redo logs in MySQL 8.0 and their impact on the MySQL performance and Operations. This covers the MySQL version still MySQL 8.0.30.
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.
MySQL Parallel Replication: inventory, use-case and limitationsJean-François Gagné
In the last 24 months, MySQL/MariaDB replication speed has improved a lot thanks to parallel replication. MySQL and MariaDB have different types of parallel replication; in this talk, I present the different implementations, with their limitations and the corresponding tuning parameters. I cover what to do to make parallel replication faster and what to avoid for maximizing parallel replication benefits. I also present benchmark results from real Booking.com workloads. Finally, I discuss some deployments at Booking.com that take advantage of parallel replication speed improvements.
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 presentation covers MySQL data encryption at disk. How to encrypt all tablespaces and MySQL related files for the compliances ? The new releases in MySQL 8.0 take care of the encryption of the system tablespace and supporting tables unlike MySQL 5.7.
MySQL Parallel Replication: All the 5.7 and 8.0 Details (LOGICAL_CLOCK)Jean-François Gagné
To get better replication speed and less lag, MySQL implements parallel replication in the same schema, also known as LOGICAL_CLOCK. But fully benefiting from this feature is not as simple as just enabling it.
In this talk, I explain in detail how this feature works. I also cover how to optimize parallel replication and the improvements made in MySQL 8.0 and back-ported in 5.7 (Write Sets), greatly improving the potential for parallel execution on replicas (but needing RBR).
Come to this talk to get all the details about MySQL 5.7 and 8.0 Parallel Replication.

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.

5. InnoDB History
● Introduced in 1995 by Finland based company called Innobase
● In 2000, Innobase started collaboration with MySQL AB
● Oracle acquired Innobase in October 2005
● Become Default storage engine for Mysql 5.5 in 2010
● JSON Support introduced in MySQL 5.7
● Separated Undo Log in MySQL 8.0
6. InnoDB Features
● ACID transaction Engine
● B+Tree Based Indexing
● Index Organised tables
● MVCC Support.
● Efficiently designed for OLTP workload.
● Foreign Key Support.
● Virtual column and Full text search support
7. InnoDB Architecture
Why InnoDB Architecture ?
● Fine Tuning needs Architecture Knowledge
● Awareness about Internals
● Data Structures ( on disk / In Memory )
● Transaction , locking . MVCC
● Checkpoint , Flushing , Purging
12. InnoDB Performance Tuning
InnoDB Buffer Pool
● Global memory for InnoDB
● Caches the Index and data pages
● Locks and Dictionary cache
● Adaptive hash index
● Change buffering
InnoDB buffer pool can be resized online in MySQL 5.7
13. InnoDB Performance Tuning
InnoDB Buffer Pool
● LRU based Flushing
● Young and Old ( LRU )
● O_Direct is best flushing
● Compressed and Uncompressed
pages in memory
14. InnoDB Performance Tuning
InnoDB Buffer Pool Config
● InnoDB_buffer_pool_size (70%-80% of Memory)
● innodb_buffer_pool_instances ( No of CPU core )
● innodb_buffer_pool_dump_pct ( > 70 % is good )
● innodb_buffer_pool_chunk_size
16. InnoDB Performance Tuning
InnoDB Change Buffer
● Present on both Disk and in memory
● Buffer pool hold Change buffer
● B+tree writes are buffered
● Restrict the size of change buffer
Innodb_change_buffering=all
Innodb_change_buffer_max_size ( 20-30 )
17. InnoDB Performance Tuning
InnoDB Adaptive Hash Index
● Hash table lookup to B+tree
● Fasten the access inside buffer pool
● Works for Primary and Secondary keys ( OLTP )
● Do not work well with text or queries with multiple join
innodb_adaptive_hash_index
innodb_adaptive_hash_index_parts
18. InnoDB Performance Tuning
InnoDB Log Buffer
● Holds the data in memory before flushing to disk
● Larger log file reduce contention
● Can Flush on every commit ( for Durability )
● Defaults work pretty well for most workloads.
Innodb_log_buffer_size
19. InnoDB Performance Tuning
InnoDB flush log at trx commit
● Controls the flushing of data from log buffer to log file.
● Supports 3 different flush behaviour
● More durability set is as default value 1
● innodb_flush_log_at_timeout controls the flush frequency
21. InnoDB Performance Tuning
InnoDB log File Size
● Two physical log files of equal size.
● Records all changes to tablespace
● Helps in crash recovery
● Overwritten when the page is flushed from buffer pool ( Checkpoint )
● innodb_log_files_in_group controls the number of files
22. InnoDB Performance Tuning
InnoDB log File Size
● Two physical log files of equal size.
● Records all changes to tablespace
● Helps in crash recovery
● Overwritten when the page is flushed from buffer pool ( Checkpoint )
● innodb_log_files_in_group controls the number of redo log files
23. InnoDB Performance Tuning
InnoDB log File Size
● Larger log file better write performance
● Tradeoff longer recovery time
● Defaults is 48 MB is low for any production workload
innodb_log_file_size=(>512M) ( Size can be calculated by innodb_os_log_written)
innodb_log_files_in_group=2
Note : PMM calculates very efficiently co-relate with checkpoint
24. InnoDB Performance Tuning
Innodb Flush method
● How data to InnoDB data files and log files is flushed ?
● default is FSYNC
● It can be numeral in MySQL 8.0 ( 0,1,2,3,4,5)
innodb_flush_method=O_DIRECT(4)
25. InnoDB Performance Tuning
Isolation Level
● How transaction isolated from each other ?
● A major role in locking along with work load
● Default Repeatable read.
transaction_isolation=read_committed/repeatable_read
26. InnoDB Performance Tuning
innodb_dedicated_server (8.0)
● Manages major tuning parameter based on your system memory
○ innodb_buffer_pool_size
○ innodb_log_file_size
○ innodb_log_file_in_group
○ innodb_flush_method
● Enable it only on dedicated MySQL server.
30. General Recommendations
● Ensure there is primary key or Unique key in all tables.
● Smaller the primary key better they will be.
● Avoid shared tablespace for innodb tables.
● Consider partition for huge tables ( query might need changes ).
● Do not make config changes without knowing its production impact.
● 80-90% of performance gain can be achieved by tweaking 4-6 variables.
