Will Nuxeo work without permissions to create functions in SQL Database?

Will Nuxeo work without permissions to create functions in SQL Database?

The environment: I configured my nuxeo.conf file to use the MySQL template, but customized the settings to use a remote MySQL server. This MySQL server is shared between different tenants, and each tenant is given a MySQL user and table. For security reasons, this MySQL instance will not grant users the ability to access the mysql.proc table or create functions, so we need to accommodate this restriction.

My attempted solution: I set “nuxeo.vcs.ddlmode=compat” in nuxeo.conf to resolve the mysql.proc issue, but I am still not allowed to create functions. This results in the following error:

You do not have the SUPER privilege and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)

at org.nuxeo.ecm.core.storage.sql.RepositoryImpl.getConnection(RepositoryImpl.java:251)

It is highly unlikely I will be getting SUPER privileges, so setting “log_bin_trust_function_creators=1” is not an option. I tried setting “nuxeo.vcs.ddlmode=ignore” to resolve the issue, but there is no longer a “repositories” table for Nuxeo to work with when I do that.

Is there a way to avoid having Nuxeo create functions when integrating with a database?

Function creation and table creation are both covered in the same way by the ddlMode. Either you give Nuxeo the rights to do everything regarding table creation and function creation, in which case it will do everything it needs, or you don't give it these rights in which case it's your responsibility as a sysadmin to create by hand everything that Nuxeo needs. ddlMode=dump,abort will help you there. See https://doc.nuxeo.com/nxdoc/repository-configuration/#database-creation-option for more.
