[jira] [Comment Edited] (OAK-1913) RDB: MariaDB (MySQL) support

    [ https://issues.apache.org/jira/browse/OAK-1913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14264561#comment-14264561 ]

-------------------------------------------------------------

OK, I redid my tests with a fresh mariaDB install, and I now see the problems you mentioned. I probably had changed some defaults.

Anyway: restricting the ID to 191 will not work in practice (we may not have proper test coverage for that)

Also: the CHAR2OCTETRATIO is indeed a constant. It is "3", as those Unicode code points that do not fit into 3 UTF-8 octets will be represented by *2* Java characters anyway.

Finally: there's currently a test that attempts to insert U+1D11E as a property value, and which is marked as expected failure for MySQL. It still fails when the DB uses a utf8mb4 default, so more research is needed here.
