   Thank you for the report.

   We reproduced and fixed this: MariaDB 12.3 changed @@global.read_only from a smallint to a boolean, which broke the scan orchestrator performs during instance discovery.

   See PR #121 , thanks @ahmetsoguksu .
   The fix is already on our master branch: the discovery query now normalizes the value with CASE WHEN UPPER(CAST(@@global.read_only AS CHAR)) IN ('0','OFF') THEN 0 ELSE 1 END, which works across MySQL and all MariaDB versions. We also added MariaDB 12.3 to our functional CI matrix (alongside MariaDB 10.6/10.11, MySQL 5.7–9.x and PostgreSQL), and discovery of MariaDB 12.3 now passes.

   The fix will ship with the next release, which we expect to publish later today. Please upgrade to that release once available.
