HA Considerations
• SLA requirements to support business objectives
• Operational capabilities
• Service agility & time to market
• Budgetary constraints
February 2015 Copyright 2015, Oracle and/or its affiliates. All rights reserved 6
• Recovery Time Objective
– Maximum length of downtime before
there is break in “business continuity”
• Recovery Point Objective
– Point in time to which data must be
recovered when service is re-
established
Tier 1
• Mission-critical services
Tier 2
• Business-critical services
Tier 3
• Task-critical services
Tier 4
• Non-critical services

Why Replicate?
• Duplicates database from a “master” to a “slave”
– Redundant copies of the data provide foundation for High Availability
– Scale out by distributing queries across the replication farm

Company Overview
Twitter’s mission: To give everyone the power to create
and share ideas and information instantly, without
barriers.
Application
A typical day sees over 500 million tweets, which means
about 5,700 per second with MySQL. Twitter achieved in
August 2013 a new World record of 143,199 Tweets Per
Second (TPS).
Why MySQL 5.6?
“Performance, replication, compression improvements,
transportable tablespaces, better monitoring &
diagnostics.” Calvin Sun, Senior Engineering Manager,
Twitter

Company Overview
Each day, over 700,000 room nights are reserved on
Booking.com. Part of the Priceline Group.
Application
Booking has relied on MySQL since 2003. Supporting 60-
70% annual growth and an agile development model.
Why MySQL?
Performance and scalability to manage a very large
event volume:
• 60 MByte/sec Event data rate
• 2 Billion Events per day
• 15 TB in MySQL for Events, lookups, monitoring
• 150 TB MySQL Event archive

Slave
Database
• Session thread: processes queries from the
application – writes data to master database &
associated events to binary log
• Dump thread: reads events from binary log and
sends them to a slave
• I/O thread: receives replication events and
stores them in slave’s relay log
• SQL thread: reads replication events from
slave’s relay log and applies them to slave
database

• Asynchronous
– MySQL Default
– In parallel: Master acks
to app and sends
transaction to slave
• Fast
• Risk of lost changes if
master dies
• Semi-Synchronous
– MySQL 5.5+ - Enhanced
in MySQL 5.7
– Serially: Master waits
for change to be
received by slave then
In parallel ack to app
and apply changes on
slave
• Intermediate latency
• Lossless (MySQL 5.7)
• Synchronous
– Only available with
MySQL Cluster
– Serially: Master waits
for change to be
applied on all slaves
before ack to app
• Higher latency
• If Active/Active, best
suited to small
transactions
• Lossless
Asynchronous vs. Synchronous Replication
February 2015 Copyright 2015, Oracle and/or its affiliates. All rights reserved 16
MySQL 5.6 Replication
February 2015
• 5x Higher slave throughput with MTS (multiple schemas)
• Reduced master impact – Binlog Group Commit
Performance and Scalability
• Global Transaction IDsSimplicity
• MySQL Replication Utilities (including auto-failover)Automation
• Crash safety
• Replication checksums
Robustness
• Time Delayed ReplicationInsurance

MySQL 5.7 Replication – Pre-GA
February 2015
• Intra-schema Multi-Threaded Slave
• Faster Master
Performance and Scalability
• Performance SchemaMonitoring
• Dynamic slave filters
• On-line CHANGE MASTER
Operational Simplicity
• Lossless Semi-Synchronous Replication

MySQL Fabric
An extensible and easy-to-
use framework for
managing a farm of MySQL
server supporting high-
availability and sharding
February 2015 Copyright 2015, Oracle and/or its affiliates. All rights reserved 21
MySQL Fabric 1.5
• High Availability
– Server monitoring with auto-promotion and
transparent application failover
• Optionally scale-out through sharding
– Application provides shard key
– Range or Hash
– Tools for resharding
– Global updates & tables
• Fabric-aware connectors rather than
proxy: Python, Java, PHP, .NET, C (labs)
– Lower latency, bottleneck-free
• Server provisioning using OpenStack etc.

MySQL Replication & MySQL Fabric HA
• MySQL Replication is the initial implementation used in HA Groups
– PRIMARY = Replication Master & receives all writes
– SECONDARY = Replication Slave & receives share of reads
• Failover
– MySQL Fabric detects failure of PRIMARY/Master
– Selects a SECONDARY/Slave and promotes it
– Updates State Store
– Updated state fetched by Fabric-aware connectors
How this effects failover

When to Consider MySQL Cluster
 Scalability demands
 Sharding for write performance?
 Latency demands
 Cost of each millisecond?
 Uptime requirements
 Cost per minute of downtime?
 Failure versus maintenance?
 Application agility
 Developer languages and frameworks?
 SQL or NoSQL?

MySQL Query Analyzer provides a consolidated view of query
activities and execution details, and has enabled Big Fish
Games to quickly identify poorly running queries and tackle
the root causes directly in the SQL code.
Why MySQL?
“With the MySQL Query Analyzer, we were able to identify and
analyze problematic SQL code, and triple our database
performance. More importantly, we were able to accomplish
this in three days, rather than taking weeks.”
