MariaDB 10.0

© SkySQL Ab. Company Confiden-al.

MariaDB 10

●  MariaDB 10.0 GA launched March 31st, 2014.

●  Application-compatible withMySQL.

●  Includes significant unique new features in scalability, replication, performance, NoSQL, operations, security.

●  Available under the GPL v2.


MariaDB 10 Scalability: Parallel Slave Replica-on

●  Sponsored by Google. ●  Allows slaves to

process update eventsin parallel.

●  Uses MariaDB 10’simproved GlobalTransaction ID (GTID).

●  MariaDB unlike MySQLcan process multipleupdates for a single database in parallel. Much better throughput.

●  Preliminary benchmarks: almost 10x faster at 12 threads. Improves scalability, reduces slave lag,

making slaves more consistent.

MariaDB 10 Scalability: Multi-Source Replication

●  Collects data for

analytics usingbuilt-in replication.

●  Aids in administrationexample: consolidatedbackups of multiple databases.

●  Uses MariaDB 10’s improvedGlobal Transaction ID (GTID).

Easier analytics, more insight,

simpler administration, fewer headaches.

MariaDB 10 Scalability: Sharding with Spider

●  Contributed by a 3rd party developer. ●  Storage engine partitions large tables

across multiple DBs. ●  No changes to the client application. ●  Developers aren’t aware, can keep

applications simple. ●  Allows for more

parallelism, scale-out. ●  Transactional storage

engine.

Web-scale, without the development hassle.

MariaDB 10 Performance: TokuDB Storage Engine

●  3rd party partner - TokuTek. ●  Drop-in replacement for

InnoDB/XtraDB. ●  Advanced indexing and

compression algorithms. ●  Transactional. ●  Up to 20x performance gain

for inserts/updates. ●  Up to 90% less disk storage. ●  Online schema changes. ●  Reduces or eliminates slave lag. ●  Best when DB doesn’t fit in memory,

and SSD longevity is important.

MariaDB 10 Performance: Op-mizer Improvements

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

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

Less I/O, CPU, memory requirements. Faster execution.


MariaDB 10 Performance: More Enhancements and Features

●  Fusion-io Atomic Writes - improvesperformance on popular SSD hardware.✔ exclusive to MariaDB 10

●  XtraDB storage engine - enhanced from InnoDB. ●  Improved InnoDB storage engine - based on MySQL 5.6. ●  Performance schema - real-time performance management. ●  Improved thread pool - better concurrent user performance.✔

exclusive to MariaDB 10

●  More optimizer improvements - higher efficiency in I/O accesses. ✔ exclusive to MariaDB 10

Faster performance, lower cost.


Fusion-‐IO page compression

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

•  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


MariaDB 10 Interoperability: CONNECT Storage Engine

●  From 3rd party developer. ●  Maps diverse data

to tables. ●  JOIN mapped data

to DB tables. ●  Flat files including CSV. ●  Tables in external DBs. ●  Generated tables

(PIVOT etc.) ●  Plug-in API for your own mappings.

Powerful tool for data integration, federation.

●  Use standard SQL queries. ●  JOIN Cassandra data

to MariaDB tables. ●  Use a MariaDB cluster

for high-availabilityaccess.

●  Bring data fromCassandra into OLTPapplications.

MariaDB 10 NoSQL Features: Dynamic Columns

●  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.
