MariaDB 10 in a nutshell

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

PERFORMANCE_SCHEMA, online ALTER TABLE etc. ●  MulN-‐source replicaNon ●  Global TransacNon ID ●  Parallel Slave Thread ●  TokuDB, Spider, Connect, Cassandra storage engines ●  SSD and Flash storage enhancements ●  User roles ●  More administraNon and instrumentaNon commands...

OpNmizer 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 raNo is leading to bemer performance and there are less writes to disk.

●  MulN-‐threaded flush provides bemer throughput and decreases operaNon latencies delivering a performance boost

Group Commit

●  binlog_commits ●  Total number of

transacNons commimed to the binary log

●  binlog_group_commits Total number of groups of transacNons commimed to the binary log

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

Global TransacNon ID

Parallel Slave Thread ReplicaNon ●  Sponsored by Google ●  TransacNons 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 mulN-‐source replicaNon).

●  slave_parallel_threads ●  Number of parallel threads on

the slave node ●  slave_parallel_max_queued

●  Memory used to read ahead in relay log

MulN-‐source ReplicaNon

●  Data parNNoned over many masters can be pulled together onto one slave for analyNcal 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 mulN-‐source can be used for replicaNng 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 ●  AutomaNc node

provisioning ●  ReplicaNon is synchronous

Galera Replication

MariaDB MariaDB MariaDB


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 administraNon


Spider

●  Spider is a storage engine based on the MySQL parNNoning features, with built-‐in sharding capabiliNes

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

●  It supports XA transacNons and mulNple storage engines (InnoDB, MyISAM etc.)

●  Developed by Kentoku Shiba, available on Launchpad, first introduced in 2008 and now available in MariaDB 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 and Business AnalyNcs

●  Simplifies the export/import of data from/to MariaDB, to/from other data sources


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
