MariaDB Cluster limit with subqueries

Details

    Description

      We are experiencing issues with creating view with multiple subqueries. The create view statement is in create_view_query.sql. It ran fine when I directly run the select statement against the cluster. When I ran the create view statement, I can select but other actions will hang and timeout. I have to rebuild the cluster in order to fix it. I have tried the method state in this link:
      http://galeracluster.com/documentation-webpages/clusterstallonalter.html

      but it doesn't help.

      Is there any limitation on creating view with multiple subqueries in select statement?

      I have attach all tables' schema as create_view_issue.sql and the server setup as variables.txt.

      Thanks

          "When I ran the create view statement, I can select but other actions will hang and timeout." - does it mean that the view is created and then select from that view executed without problems? What other actions have you performed?

          Yes, and I also can perform select action against other tables too. However, I couldn't do any insert, update, delete action. They will all hand and execution timeout.
