Flyway cannot create schema table on Galera cluster (MariaDB)

[erindru]

What version of Flyway are you using?

4.0

What database are you using (type & version)?

MariaDB 10.1.13. Note: this issue is caused by setting innodb_force_primary_key=1 which is required for the Galera cluster to work properly. You dont need to set up a Galera cluster to reproduce this issue, you can do it by setting that property on a normal MariaDB instance.

What operating system are you using?

Mac OSX and Linux

What did you do?

Ran Flyway.migrate() and observed the following error:

What did you expect to see?

The schema_version table created successfully

What did you see instead?

A This table type requires a primary key error returned from the database server

Since you use DB-specific SQL for each database, the following script can be updated to create a primary key at the same time as the table instead of directly afterwards: https://github.com/flyway/flyway/blob/master/flyway-core/src/main/resources/org/flywaydb/core/internal/dbsupport/mysql/createMetaDataTable.sql

I will submit a pull request for this.
