2 MySQL Enterprise Edition
MySQL is the world's most popular open source database. Whether you are
a fast growing web property, software vendor, a large organization or an
SMB MySQL can cost-effectively help you deliver high performance,
scalable database applications. If you are currently using MySQL, you
probably started with MySQL Community Edition. In fact, in many instances
MySQL enters an organization via an application development project and
makes its way into the data center when the application is promoted for
production use. Challenges arise when these applications become vital to
business revenues or key business functions.
The most common
challenges around running MySQL and other open source technologies are
revealed by a simple line of questioning:
•
•
How will you ensure you are using the most reliable, secure, scalable,
up-to-date version?
How will you know:
o If a server or applications is down?
© 2017, Oracle Corporation and/or its affiliates
3
•
•
•
•
•
o If there is a replication master/slave synchronization or latency
issue?
o If something else is affecting the performance of a server?
Will you know:
o If MySQL is configured to scale-out as your application data and
customer base grows?
o How to configure MySQL variables to ensure your applications run
at their peak performance?
How will you:
o Identify security loopholes in MySQL servers?
o Know when there have been security alterations on a MySQL
server?
o Seamlessly add auditing compliance to your new and existing
MySQL applications?
How will you:
o Optimize your database designs and queries before they are
migrated into your production environments or included in your
products?
o Ensure replicated servers are configured correctly for performance
and scalability?
o Monitor and tune poorly performing user/application SQL code?
How will you integrate MySQL with your existing security standards and
infrastructure?
If you or your customers also use the Oracle Database, how can you:
o Manage MySQL high availability using existing Oracle solutions?
To help you answer these questions with confidence MySQL provides
MySQL Enterprise Edition. MySQL Enterprise Edition is a commercial
offering comprised of the MySQL database with security, encryption,
auditing, high availability and scalability extensions, online backup,
monitoring, management, and visual database design and SQL
development tools. MySQL Enterprise Edition is backed by Oracle Premier

6 MySQL Enterprise Encryption
To protect sensitive data throughout its lifecycle, MySQL Enterprise
Encryption provides industry standard functionality for asymmetric
encryption (Public Key Cryptography). MySQL Enterprise Encryption
provides encryption, key generation, digital signatures and other
cryptographic features to help organizations protect confidential data and
comply with regulatory requirements including HIPAA, Sarbanes-Oxley, and
the PCI Data Security Standard.
MySQL Enterprise Encryption gives DBAs and Developers the tools they
need for:
•
•
•
•
•
•
•
Asymmetric Public Key Encryption (RSA)
Asymmetric Private Key Decryption (RSA)
Generate Public/Private Key (RSA, DSA, DH)
Derive Symmetric Keys from Public and Private Key pairs (DH)
Digitally Sign Data (RSA, DSA)
Verify Data Signature (RSA, DSA)
Validation Data Authenticity (RSA, DSA)
© 2017, Oracle Corporation and/or its affiliates
8
This enables software developers to encrypt data by using RDS, DHS and
DH encryption algorithms without changing existing applications.
7 MySQL Enterprise Transparent Data Encryption
(TDE)
MySQL Enterprise Transparent Data Encryption (TDE) protects your critical
data by enabling data-at-rest encryption in the database. It protects the
privacy of your information, prevents data breaches and helps meet
regulatory requirements including the Payment Card Industry Data Security
Standard (PCI DSS), Health Insurance Portability and Accountability Act
(HIPAA) and numerous others.
MySQL Enterprise TDE enables data-at-rest encryption by encrypting the
physical files of the database. Data is encrypted automatically, in real time,
prior to writing to storage and decrypted when read from storage. As a
result, hackers and malicious users are unable to read sensitive data from
tablespace files, database backups or disks.
MySQL Enterprise TDE uses a two-tier encryption key architecture,
consisting of a master encryption key and tablespace keys which provides
easy key management and rotation. Tablespace keys are managed
automatically behind the scenes while the master encryption key is stored in
a centralized key management solution such as Oracle Key Vault, which
enforces clear separation of keys from encrypted data.
8 MySQL Enterprise Firewall
MySQL Enterprise Firewall guards against cyber security threats by
providing real-time protection against database specific attacks, such as an
SQL Injection. MySQL Enterprise Firewall monitors for database threats,
automatically creates a whitelist of approved SQL statements and blocks
unauthorized database activity.
© 2017, Oracle Corporation and/or its affiliates

•
•
•
Real-time Threat Monitoring - All incoming queries pass through a SQL
analysis engine and are matched against an approved Whitelist of
expected SQL statements.
Block Suspicious Traffic - Statements that do not match the approved
whitelist are blocked, logged and can be analyzed to help block a
potential SQL injection attack.
Learn and Build Whitelists - Automatically create user specific whitelists
of pre-approved SQL statements using a self-learning system.
Transparent Protection - MySQL Enterprise Firewall requires no
changes to your application regardless of development language,
framework or 3rd party application.
High Performance - MySQL Enterprise Firewall runs within each
MySQL instance and provides scale-out performance.
Logging - MySQL Enterprise Firewall tracks and provides metrics on
both allowed and blocked SQL statements. Blocked statements are
logged for inspection and alerting.
9 MySQL Enterprise Audit
Today’s web-based applications have evolved from nice-to-have enablers to
the mission-critical revenue generating mechanisms that characterize the
modern business model. In this virtual marketplace, PCI compliance
guidelines ensure credit card data is secure within e-commerce apps. From
a corporate standpoint, Sarbanes-Oxley, HIPAA and other government
imposed mandates guard the medical, financial, public sector and other
personal data centric industries with required logging, archiving and "upon
request" access to audit trails that reveal the eyes and hands that have
viewed and acted upon the most sensitive of data. In all use cases,
requirements for capturing application level user activity are most commonly
implemented on the back-end database.
With this in mind, MySQL 5.5 and higher provides an open pluggable audit
interface that enables all MySQL users to write their own auditing solutions
based on application specific requirements. To help users quickly and
seamlessly add auditing compliance to their existing applications MySQL
© 2017, Oracle Corporation and/or its affiliates
10
Enterprise Edition includes MySQL Enterprise Audit, an easy to use policybased auditing solution that enables users to:
•
•
Powerful Filtering to Protect Sensitive Data - Define what you audit
using templates or design highly custom filters using simple JSON filter
definition. Filter on connections, users, table access, access type,
statement status (success/failure), query content, and more. Meet Regulatory Compliance Standards - Provide the data your
organization and auditors need to be in compliance with requirements
including PCI, HIPAA, FERPA, SOX and more
•
Achieve Security Goals through Comprehensive Auditing - Trust but
verify DBA activity, prove your data’s validity and perform forensic
analysis to investigate or discover data breaches.
•
Easy Integration with Audit Vaults and Stores - Externally archive
and analyze XML-based audit logs with ease using Oracle Audit Vault
and other third party solutions including Splunk.
Dynamic and Easy to Manage - Dynamically enable/disable audit
stream, change filtering, and more with no downtime. Automatically
rotate audit log files based on size.
Low Overhead - Collects critical audit data with minimal performance
impact. Use fine grain filtering to minimize audit log size and IO impact.

10 MySQL Enterprise Scalability
By default the MySQL Database provides a complex thread-handling model
that provides excellent throughput and performance for online and webbased applications. User connections are mapped to execution threads on
a one-to-one basis with each connection/thread assignment remaining intact
until the connection is terminated by the client. Under this model the
MySQL Database provides scalable concurrency of both user connections
and query executions.
Figure 4: Default Thread Handling Model
While this model serves and scales most web deployment use cases very
well it does have the potential to limit scalability as connection and query
© 2017, Oracle Corporation and/or its affiliates
12
loads increase at an increasing rate. This use case is becoming more
common as application clients now extend far beyond the keyboard to
mobile and other web-enabled devices. For the most highly-trafficked
applications when concurrent connections grow from hundreds to thousands
and associated query executions grow proportionally scalability challenges
and limitations with the default model are potentially exposed:
•
•
•
•
Current model does not prioritize connection queries for execution,
regardless of the number that have been submitted or that are in a
“wait” status. No prioritization of queries means that all attempt to
execute in parallel with no regard for server resource limitations.
More concurrency of query executions requires significantly more
server memory. In an extreme case if the amount of memory
needed by all active connections exceeds server memory, the
MySQL server may revert to memory/disk swapping, which will
greatly impact user response times.
More query executions also leads to more cache flushing, which
leads to more cache misses and disk I/O requests. More disk I/O
leads to longer query execution and user response times.
Write intensive applications are impacted significantly as concurrent
DML statement execution times can degrade exponentially as disk
I/O increases.
The MySQL Thread Pool
To meet these challenges around the most demanding “mobilized”
application user and workloads MySQL Enterprise Edition provides the
MySQL Thread Pool. The Thread Pool is a user configurable option that
provides an efficient, alternate thread-handling model designed to sustain
performance and scalability as concurrent user loads continue to grow. In
these use cases the Thread Pool addresses the limitations to scalability by:
•
•
•
Managing/controlling query execution until the MySQL server has
the resources to execute it.
Splitting threads into managed Thread Groups.
Inbound
connections are assigned to a group via a round-robin algorithm and
the number of concurrent connections/threads per group is limited
based on queue prioritization and nature of queries awaiting
execution. Transactional queries are given a higher priority in queue
than non-transactional, but queue prioritization can be overridden at
the user level as needed.
Avoiding deadlocks when queries are stalled or executing for long
period of time.

Figure 5: MySQL Thread Pool
The result is sustained performance and scalability as concurrent user
connections and work loads grow as shown here in a benchmark conducted
using MySQL 5.6:

Read/Write activity with Thread Pool
© 2017, Oracle Corporation and/or its affiliates
14
Figure 7: MySQL Enterprise Edition provides 18x better scalability for OLTP Read
activity with Thread Pool
SysBench OLTP benchmarks show that the MySQL Thread Pool provides a
significant improvement in sustained performance and scalability for
applications that service a growing number of concurrent user connections
and query executions. The graphs above show read/write activity improves
by a factor of 60 while read only activity improves by a factor of 18, both at
8,192 concurrent connections, with the Thread Pool enabled.

Replication, MySQL Router, and MySQL Shell, so you don’t have to rely on
external tools, scripts or other components. Plus, it leverages proven
MySQL features including InnoDB, GTIDs, binary logs, multi-threaded slave
execution, multi-source replication and Performance Schema. A MySQL
InnoDB Cluster can be set up in less than five minutes and managed using
the scriptable AdminAPI in the MySQL Shell.
MySQL InnoDB Cluster delivers an integrated, native, HA solution for your
databases
Elasticity
With Group Replication, a set of servers coordinate together to form a
group. The group membership is dynamic and servers can leave, either
voluntarily or involuntarily, and join at any time. The group will automatically
reconfigure itself as needed and ensure that any joining member is
synchronized with the group. This makes it easy to quickly scale your total
database capacity up and down as needed.
Failure Detection
Group Replication implements a distributed failure detector to find and
report servers that have failed or are no longer participating in the group and
the remaining members in the group coordinate to reconfigure the
membership.
Fault Tolerance
© 2017, Oracle Corporation and/or its affiliates
16
Group Replication builds on an in-house implementation of the popular
Paxos distributed algorithm to provide distributed coordination between
servers. In order for a group to continue to function, it requires a majority of
the members to be online and for them to form an agreement on every
change. This allows your MySQL databases to safely continue to operate
without manual intervention when failures occur, without the risk of data loss
or data corruption.
Self-Healing
If a server joins the group, it will automatically bring itself up to date by
synchronizing its state from an existing member. In the event that a server
leaves the group, for instance it was taken down for maintenance, the
remaining servers will see that it has left and will reconfigure the group
automatically. When that server later rejoins the group, it will automatically
re-synchronize with the group again.
Monitoring
Performance Schema tables provide clear and detailed information and
statistics on individual members and for the group as a whole.
HA for MySQL Client Applications using MySQL Router
MySQL Router 2.1 allows you to easily migrate your standalone MySQL
instances to natively distributed and highly available InnoDB clusters without
affecting existing applications. The new metadata_cache plugin provides
transparent client connection routing, load balancing, and failover into your
InnoDB clusters.
Easy and Accessible using MySQL Shell
MySQL Shell provides the developer and DBA with a single intuitive,
flexible, and powerful interface for all MySQL related tasks. The new
AdminAPI makes it easy to create, monitor, and manage InnoDB clusters—
including MySQL Router instances—in a self describing natural language
interface, without the need to understand low level concepts, configuration
options, or other complex aspects. MySQL Shell makes InnoDB clusters
easy and accessible for everyone.
12 MySQL Enterprise Backup
Backup
MySQL Enterprise Backup performs online "Hot", non-blocking backups of
MySQL databases. Full backups can be performed on all InnoDB data while
MySQL is online, without interrupting queries or updates. In addition,
incremental backups are supported so that only data that has changed from
© 2017, Oracle Corporation and/or its affiliates
17
a previous backup are backed up. Also partial backups are supported when
only certain tables or tablespaces need to be backed up.
Restore
MySQL Enterprise Backup restores data from a full backup with full
backward compatibility. Consistent Point-in-Time Recovery (PITR) enables
restoration to a specific point in time. Using MySQL backups and binlog, you
can also perform fine-grained roll forward recovery to a specific transaction.
A partial restore allows recovery of targeted tables or tablespaces. In
addition, you can restore backups to a separate location, or create clones
for fast replication setup or administration.
Compression
MySQL Enterprise Backup supports creating compressed backup files,
typically reducing backup size from 70% to over 90% when compared to the
size of actual database files, reducing storage and other costs.
Direct to Cloud Storage
Support for Oracle Storage Cloud, AWS S3 (Simple Storage Service) API to
backup and restore direct to inexpensive Cloud Storage (S3, Swift, and
more)
13 MySQL Enterprise Monitor

data size and date/time of when query was “first seen”:
o Total Executions helps you see when queries are running too
often or in error.
Even properly tuned queries cause
performance problems when they run excessively.
o SQL Warning and Error counts help you see queries that did
not finish or that returned incorrect result sets. These
executions may never be found using other query monitoring
options.
o Total Execution Time helps you see the most “expensive”
queries across all of the servers. This value helps you see
where systems are spending the most time and resources and
where you should focus your tuning efforts.
o Total Data Size (Rows and Bytes) helps you analyze if
queries are returning more data than your application is using.
Sorting on this value, examining the underlying queries and

15 MySQL Workbench Enterprise Edition
MySQL Workbench is a unified visual development tool that includes
advanced data modeling capabilities, a visual SQL editor and
comprehensive administration tools for database design, query
development, server configuration, user administration, and wizard-driven
database migrations.
Design
MySQL Workbench enables a DBA, developer, or data architect to visually
design, model, generate, and manage databases. It includes everything a
data modeler needs for creating complex ER models, forward and reverse
engineering, and also delivers key features for performing difficult change
management and documentation tasks that normally require much time and
effort.

Migration project management - allows migrations to be
configured, copied, edited, executed and scheduled.
Source and Target selection - allows users to define specific data
sources and to analyze source data in advance of the migration.
Object migration - allows users to select objects to migrate, assign
source to target mappings where needed, edit migration scripts and
create the target schema.
Data migration - allows users to map source and target data and
data types, set up data transfer and assign post data transfer events
where needed.
