S3 storage engine fails to load due to plugin_maturity

    XMLWordPrintable

Details

    Description

      The S3 storage engine currently has plugin maturity alpha in MariaDB Community Server 10.5.4:

      https://github.com/MariaDB/server/blob/8394979aae274a19689102420ebb86580e26f92e/storage/maria/ha_s3.cc#L1080

      When you install the package for the S3 storage engine on Debian or Ubuntu, it installs a configuration file that tries to load the plugin:

      $ cat /etc/mysql/mariadb.conf.d/s3.cnf 
      [mariadb]
      		 
      plugin-load-add=ha_s3
      		 
       
      		 
      #
      		 
      # Uncomment and configure the S3 engine
      		 
      #
      		 
      #s3-host-name=s3.amazonaws.com
      		 
      #s3-protocol-version=Amazon
      		 
      #s3-bucket=...
      		 
      #s3-access-key=...
      		 
      #s3-secret-key=...
      		 
      #s3-region=eu-north-1

      This configuration file does not set plugin_maturity=alpha, so this configuration file causes the plugin to fail to load:

      2020-06-23  0:37:15 0 [ERROR] mysqld: Can't open shared library 'ha_s3.so' (errno: 1, Loading of alpha plugin S3 is prohibited by --plugin-maturity=gamma)
      		 
      2020-06-23  0:37:15 0 [ERROR] Couldn't load plugins from 'ha_s3.so'.

      Should s3.cnf set plugin_maturity=alpha, so that the plugin can be loaded successfully?
