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
● Memory used to read aheadin relay log
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 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

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
© SkySQL – The MariaDB Company
Dynamic ColumnsStore Unstructured Data
● Store unstructured data in MariaDB tables with a simple API.● Use MariaDB’s indexing and transactions to manipulate
“document” style data fast and consistently.● Nest sets of dynamic columns inside of other dynamic columns -
hierarchical structuring.● Include multiple rows with dynamic columns in transactions.
Process unstructured data in the same way as NoSQL ,but with the power of MariaDB
