Galera Synchronous Replication

MariaDB 10 in a nutshell

● MariaDB 5.5 features +● MySQL 5.6 backported features - InnoDB/XtraDB,

PERFORMANCE_SCHEMA, online ALTER TABLE etc.● Multi-source replication● Global Transaction ID● Parallel Slave Thread● TokuDB, Spider, Connect, Cassandra storage engines● SSD and Flash storage enhancements● User roles● More administration and instrumentation commands...

Optimizer Improvements

● Of 29 distinct enhancements noted, 28 are in MariaDB 10. Just 1 only in MySQL 5.6.

● Enhancements include:● Disk access optimizations.● JOIN optimizations.● Subquery optimizations.● Optimized derived tables and views.● Execution control.● Optimizer control.● EXPLAIN improvements.

Fusion-IO page compression

● Atomic writes gives a performance increase of about 30%. By enabling fast checksum for XtraDB it’s 50%

● By using page compression the compression ratio is leading to better performance and there are less writes to disk.

● Multi-threaded flush provides better throughput and decreases operation latencies delivering a performance boost

https://blog.mariadb.org/significant-performance-boost-with-new-mariadb-page-compression-on-fusionio

Group Commit

● binlog_commits● Total number of

transactions committed to the binary log

● binlog_group_commitsTotal number of groups of

transactions committed to the binary log

When sync_binlog=1 it is the number of fsync()’s

Global Transaction ID

Parallel Slave Thread Replication● Sponsored by Google● Transactions are applied in parallel if they have been executed in parallel on the

master.● It works beyond the boundaries of MySQL 5.6 parallel slave

● Parallel threads apply to:● Queries that are run on the master in one group commit.● Queries that are from different domains.● Queries from different masters

(when using multi-sourcereplication).

● slave_parallel_threads● Number of parallel threads on

the slave node● slave_parallel_max_queued

● Number of parallel threads onthe slave node

Multi-source Replication

● Data partitioned over manymasters can be pulledtogether onto one slave foranalytical queries

● Many masters can replicate tothe same slave and a completebackup can be done on the slave

● Newer hardware usually provides more performance. Usually all hardware isn’t upgraded at once and multi-source can be used for replicating many masters to a powerful new slave.

● Up to 64 masters

MariaDB in the MySQL World

MariaDB Galera Cluster

● Read & Write access to any node

● Client can connect to any node

● There can be several nodes● Automatic node

provisioning● Replication is synchronous Galera Replication

MariaDB MariaDB MariaDB

TokuDB

● Drop-in replacement for InnoDB/XtraDB developed by Tokutek.

● Advanced indexing andcompression algorithms.

● Up to 20x performance gainfor inserts/updates.

● Up to 90% less disk storage.● Online schema changes and online backup

features.● Simplified administration

Spider

● Spider is a storage engine based on the MySQL partitioning features, with built-in sharding capabilities

● Tables of different MariaDB instances are handled as if they are on the same instance

● It supports XA transactions and multiple storage engines (InnoDB, MyISAM etc.)

● Developed by Kentoku Shiba,available on Launchpad,first introduced in 2008and now available inMariaDB 10

Connect

● Connect enables MariaDB to use external data as they were standard tables in the server

● Data is not loaded into MariaDB● Integrates/access data directly in many non-

MariaDB formats● Simplifies the ETL procedures in

Business Intelligence andBusiness Analytics

● Simplifies the export/import ofdata from/to MariaDB, to/fromother data sources

Even more innovative features

● Role-based access control● SHOW EXPLAIN FOR thread● Explain on slow query log● Cassandra storage engine● Virtual and dynamic columns● HandlerSocket plugin● Audit and PAM plugins

MariaDB 10.1

● Single distribution for clustered and non-clustered MariaDB● 5.6, 5.7 and WebscaleSQL features● Portable tablespaces● Improved thread management● Kerberos authentication support● GIS improvements● Windowing functions● inner and outer database security and encryption● More NoSQL enhancements
