I've notifced this code in RDBDocumentStore:

int isolation = con.getTransactionIsolation();
       String isolationDiags = RDBJDBCTools.isolationLevelToString(isolation);
       if (isolation != Connection.TRANSACTION_READ_COMMITTED) {
           LOG.info("Detected transaction isolation level " + isolationDiags + 
" is "
                   + (isolation < Connection.TRANSACTION_READ_COMMITTED ? 
"lower" : "higher") + " than expected "
                   + 
RDBJDBCTools.isolationLevelToString(Connection.TRANSACTION_READ_COMMITTED)
                   + " - check datasource configuration");
       }

Now the default isolation level for MariaDB is REPEATABLE_READ so it will be 
logged that log, I'm asking if there is some known restriction  or strong 
recomendation in using READ_COMMITTED? I believe not because it is only an info 
log but why does it is expected?

Thanks,

Subject: Re: Problems in using RDB DocumentStore on mariadb

Hi just to let you know that I've started working to OAK-11185 where I will add 
new profile rdb-mariadb, modify RDBDocumentStoreDB to add new enum MariaDB and 
then I'll see for other needs.

Best regards

Please be patient. It shouldn't take long.

Regarding Git: yes, that's a bit painful as long as you need to fork.
But be aware, I'm not a Git expert either.

Back when I had to do this with Sling:

- to work on new things, create a new work with a different name, create
a branch, and work there

- for your existing PR, this should help:
