How do I connect to iccube using Snowflake?

after copying the latest version of the Snowflake driver in to the lib folder of iccube, starting the server and then performing the following:

  1. Schema create - Wizard (Dimensions/Measures -> Table)
  2. Relational Database
  3. Connection details....

I get the following error.

Snowflake jdbc driver throws a 'SQLFeatureNotSupportedException' with an empty message when calling setReadOnly to the connection.

We fixed this in our dev branch and will be available in the next release or as a pre-release.

PS: Discovering tables doesn't work very well, as a workaround you might add SQL queries as tables.
