db_max_retries = 20	(IntOpt) maximum db connection retries before error is raised. (setting -1 implies an infinite retry count)
db_max_retry_interval = 10	(IntOpt) max seconds between db connection retries, if db_inc_retry_interval is enabled
db_retry_interval = 1	(IntOpt) seconds between db connection retries
idle_timeout = 3600	(IntOpt) Timeout before idle sql connections are reaped
max_overflow = None	(IntOpt) If set, use this value for max_overflow with sqlalchemy
max_pool_size = None	(IntOpt) Maximum number of SQL connections to keep open in a pool
max_retries = 10	(IntOpt) Maximum db connection retries during startup. (setting -1 implies an infinite retry count)
min_pool_size = 1	(IntOpt) Minimum number of SQL connections to keep open in a pool
mysql_sql_mode = TRADITIONAL	(StrOpt) The SQL mode to be used for MySQL sessions. This option, including the default, overrides any server-set SQL mode. To use whatever SQL mode is set by the server configuration, set this to no value. Example: mysql_sql_mode=
