I'm reading the documentation about ODK Sync Endpoint, but I haven't seen any minimum/recommended versions for the databases supported by this tool. It's mentioned that PostgreSQL, MySQL and MS SQL Server are supported, but shouldn't there be a minimum version for each of these?
Good catch. We should be specifying that in the documentation.
I have created an issue to improve the documentation:
Currently Sync-Endpoint is being tested against:
PostGres version 9.6
MySql version 5.7
I see a dependency for MS SQLServer v7.0.0.jre8 in https://github.com/opendatakit/sync-endpoint/blob/master/pom.xml, if that helps.
