Re: [xwiki-devs] [Proposal] Update database support strategy

Hi devs, We currently have https://dev.xwiki.org/xwiki/bin/view/Community/DatabaseSupportStrategy However, it doesn’t say explicitly which versions we officially support: * For HSQLDB it says 2.3.3 which is wrong since the latest version is 2.4.1 * For MySQL it says 5.x but doesn’t specify which specific version(s) * Same for other DBs We cannot really support every versions since supporting means testing too. So what I propose: Question 1: definition * We say we support the latest stable version of the databases for a given version cycle ** For MySQL, it’s the latest of the 5.x cycle, which is 5.7.24 as of today (see https://hub.docker.com/_/mysql/) ** For PostgreSQL, it’s the latest of the 9.x cycle, which is 9.6.10 as of today (see https://hub.docker.com/_/postgres/) ** For Oracle, it’s the latest of the 11.x cycle, which is 11.2.0.4.0 as of today (see https://www.oracle.com/technetwork/database/enterprise-edition/downloads/in…)

Question 2: review what we support * For MySQL I think we could also start supporting MySQL 8.x (ie the latest version of that cycle). We have an issue open for it currently: https://jira.xwiki.org/browse/XWIKI-15215 * For PostgreSQL we could also start supporting versions 11.x (ie the latest version of that cycle) * For Oracle, we could also start supporting versions 12.x (ie the latest version of that cycle)

Question 3: decide if we drop some support * Is there any cycle that we should support for? Right now I think that MySQL 5.x is still heavily used, same for postgreSQL 9.x I guess. Don’t know for Oracle. * Any idea?

So WDYT about the 3 questions? Thanks -Vincent
