13. 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...

14. 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.

15. 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

16. Group Commit
● binlog_commits
● Total number of
transactions committed to
the binary log
● binlog_group_commits
Total number of groups of
transactions committed to
the binary log
When sync_binlog=1 it is the
number of fsync()’s

17. Global Transaction ID

18. 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-source
replication).
● slave_parallel_threads
● Number of parallel threads on
the slave node
● slave_parallel_max_queued
● Memory used to read ahead
in relay log

19. Multi-source Replication
● Data partitioned over many
masters can be pulled
together onto one slave for
analytical queries
● Many masters can replicate to
the same slave and a complete
backup 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 and
compression algorithms.
● Up to 20x performance gain
for inserts/updates.
● Up to 90% less disk storage.
● Online schema changes and online backup
features.
● Simplified administration

22. © SkySQL – The MariaDB Company
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 2008
and now available in
MariaDB 10

23. © SkySQL – The MariaDB Company
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 and
Business Analytics
● Simplifies the export/import of
data from/to MariaDB, to/from
other data sources

24. © SkySQL – The MariaDB Company
Dynamic Columns
Store 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
