> The database failover behavior does not work as expected with MySQL / MariaDB on the databases.  Based on a reading of the documentation and source, I would expect this config in res_odbc to behave differently than it does:
> [config]
> enabled => yes
> dsn => MySQL
> username => user
> password => hidden
> pre-connect => yes
> sanitysql => select 1
> idlecheck => 30
> share_connections => yes
> connect_timeout => 2
> negative_connection_cache => 300
> [config_2]
> enabled => yes
> dsn => MySQL-2
> username => user
> password => hidden
> pre-connect => yes
> sanitysql => select 1
> idlecheck => 30
> share_connections => yes
> connect_timeout => 2
> negative_connection_cache => 300
> Based on my reading, a connect timeout getting hit should cause a negative cache where new connections are not attempted for 300 seconds.  That does not occur in practice.  The server continually attempts to reconnect to the server, meanwhile the entire system becomes totally unusable until the database connection is restored.
