# IMPORTANT INFORMATION REGARDING THIS CONFIGURATION FILE:                             
########################################################################################
# On startup, ProxySQL reads its config file (if present) to determine its datadir. 
# What happens next depends on if the database file (disk) is present in the defined
# datadir (i.e. "/var/lib/proxysql/proxysql.db").
#
# If the database file is found, ProxySQL initializes its in-memory configuration from 
# the persisted on-disk database. So, disk configuration gets loaded into memory and 
# then propagated towards the runtime configuration. 
#
# If the database file is not found and a config file exists, the config file is parsed 
# and its content is loaded into the in-memory database, to then be both saved on-disk 
# database and loaded at runtime.
#
# IMPORTANT: If a database file is found, the config file is NOT parsed. In this case
#            ProxySQL initializes its in-memory configuration from the persisted on-disk
#            database ONLY. In other words, the configuration found in the proxysql.cnf
#            file is only used to initial the on-disk database read on the first startup.
#
# In order to FORCE a re-initialise of the on-disk database from the configuration file 
# the ProxySQL service should be started with "systemctl start proxysql-initial".
