What are the differences between MySQL Community and MySQL Enterprise Server 5.7

The MySQL Server itself

The differences between the MySQL Community Server and the MySQL Enterprise Server 5.7 are as follows as claimed by Oracle:

  • The license of the MySQL Server itself.
  • Only MySQL Enterprise Edition has the Enterprise plug-ins (Thread Pool, PAM, Audit, etc.)
  • Certifications and Indemnification support for the MySQL Enterprise Server.
  • The MySQL Community Server statically links against yaSSL and readline vs MySQL Enterprise Server against OpenSSL and libedit.

The license of the MySQL Server

The MySQL Community Server is licensed under the GNU General Public License version 2 whereas the MySQL Enterprise Server is under an Oracle proprietary license as you can see from the following diffs of 2 random files:

Enterprise plug-ins of the MySQL Enterprise Server

Oracle/MySQL follows the open core business model with the MySQL Server. This means: The MySQL Community Server is the same as the MySQL Enterprise Server but the MySQL Enterprise Server has some additional modules and programs compared to the MySQL Community Server:

  • MySQL Enterprise Backup
  • MySQL Enterprise Monitor
  • MySQL Enterprise Security
  • MySQL Enterprise Audit

See also: MySQL Enterprise Edition.

If we check this in the packages we find the following additional plug-ins in the MySQL Enterprise Server:

shell> ls -la mysql-advanced-5.7.16-linux-glibc2.5-x86_64/lib/plugin:
-rwxr-xr-x 1 mysql mysql  3556085 Sep 28 19:35 audit_log.so
-rwxr-xr-x 1 mysql mysql    73855 Sep 28 19:35 authentication_pam.so
-rwxr-xr-x 1 mysql mysql  1595720 Sep 28 19:35 firewall.so
-rwxr-xr-x 1 mysql mysql  3748543 Sep 28 19:35 keyring_okv.so
-rwxr-xr-x 1 mysql mysql  2283844 Sep 28 19:35 openssl_udf.so
-rwxr-xr-x 1 mysql mysql   567032 Sep 28 19:34 thread_pool.so

MySQL Enterprise Server Certification and Indemnification support

This is legal stuff. I only care about technical problems... If you have Open Source legal questions please get in contact with us and we will direct you to lawyers which are specialised in the Open Source field.

Different libraries

The MySQL Community Server statically links against yaSSL and readline vs MySQL Enterprise Server against OpenSSL and libedit.

This is on one side a legal problem GPL vs BSD license. On the other side it is a political problem. Unfortunately the OpenSSL used in the MySQL Enterprise Server is actually a bit more feature reach than yaSSL.

We can also see the differences between the different SSL libraries when we search for the symbols:

shell> grep -ic yassl *.mysqld
community.mysqld:1118
enterprise.mysqld:0

shell> grep -ic openssl *.mysqld
community.mysqld:3
enterprise.mysqld:38

shell]> grep -i openssl community.mysql
yaOpenSSL_add_all_algorithms
_ZL16Sys_have_openssl
_ZN8TaoCrypt18RSA_Public_Decoder17ReadHeaderOpenSSLEv

Other technical comparisons

Beside of the described findings above I am a very curious child...

It seems like we can find here some build info:

Here you can see some differences I cannot explain. Possibly they come from the use of the different SSL and libedit/readline libraries?

The files are basicaly of the same type/style:

When we look into the symbol tables of those 6 binaries we can see some differences which IMHO are mostly caused because of the 2 different set of libraries:

MySQL Enterprise Server and MySQL Community Server packages

This is not directly MySQL Server related but it affects operation as well: We found today that the MySQL Enterprise Server RPM package and the MySQL Community Server packages were not prepared the same. The MySQL Enterprise Server for MySQL 5.7.15 package was still using sysV init scripts whereas the MySQL 5.7.15 Community Server package seems to use already SystermD unit files (since MySQL 5.7.6: Managing MySQL Server with systemd). This has change from MySQL 5.7.15 to MySQL 5.7.16 Enterprise Server. So if you side-grade from MySQL Community to MySQL Enterprise Server you might experience some surprises...

Comments

I was informed that nowadays MySQL Enterprise Server and MySQL Community Server use both EditLine (since MySQL 5.6?).

I found out that we were wrong in this. We have taken RHEL6 MySQL RPM packages instead of RHEL7 packages. This is the reason why the installation was not smooth (but it worked) and why still old sysV init scripts were used.
