Aviso do MySQL Workbench ao conectar-se ao MariaDB

Question

Ao usar o MySQL Workbench 6.3 no Kubuntu 15.10 e na versão do MariaDB Server: 10.0.22-MariaDB-0ubuntu0.15.10.1 (Ubuntu), recebo o seguinte aviso.

Isso é esperado?

Incompatible/nonstandard server version or connection protocol detected (10.0.22).

A connection to this database can be established but some MySQL Workbench features may not work properly since the database is not fully compatible with the supported versions of MySQL.

MySQL Workbench is developed and tested for MySQL Server versions 5.1, 5.5, 5.6 and 5.7

Succcessfully made the mysql connection

Information related to this connection:

Host: localhost Port: 0 User: serg SSL: not enabled

A successful MySQL connection was made with the parameters defined for this connection.

    

Answer 1

TL; DR
Sim, isso é esperado, porque o MySQL Workbench é um produto Oracle e não suporta oficialmente o MariaDB, que na verdade é um concorrente do MySQL. O Workbench está avisando sobre incompatibilidades potenciais , não necessariamente aquelas detectadas. Na maioria dos casos, pode ser ignorado com segurança.

Detalhes

O artigo de base de conhecimento da MariaDB sobre compatibilidade com o MySQL descreve melhor o relacionamento ( ênfase minha):

For all practical purposes, MariaDB is a binary drop in replacement of the same MySQL version (for example MySQL 5.1 -> MariaDB 5.1, MariaDB 5.2 & MariaDB 5.3 are compatible. MySQL 5.5 is compatible with MariaDB 5.5 and also in practice with MariaDB 10.0). What this means is that:

• Data and table definition files (.frm) files are binary compatible.
  • See note below for an incompatibility with views!
• All client APIs, protocols and structs are identical. All filenames, binaries, paths, ports, sockets, and etc... should be the same.
• All MySQL connectors (PHP, Perl, Python, Java, .NET, MyODBC, Ruby, MySQL C connector etc) work unchanged with MariaDB.
  • There are some installation issues with PHP5 that you should be aware of (a bug in how the old PHP5 client checks library compatibility).
• The mysql-client package also works with MariaDB server.
• The shared client library is binary compatible with MySQL's client library.

This means that for most cases, you can just uninstall MySQL and install MariaDB and you are good to go. (No need to convert any datafiles if you use same main version, like 5.1). You must however still run mysql_upgrade to finish the upgrade. This is needed to ensure that your mysql privilege and event tables are updated with the new fields MariaDB uses.

We do monthly merges with the MySQL code base to ensure we keep up our compatibility and get any and all features and bug fixes Oracle adds.

Tudo o que foi dito, existem algumas incompatibilidades que podem ou não afetar você. O artigo da KB vinculada tem uma seção sobre incompatibilidades conhecidas entre diferentes versões do MySQL e do MariaDB. Consulte a seção da sua versão do MariaDB para obter notas que possam afetá-lo.
