-# This is the Dendrite configuration file.
-#
-# The configuration is split up into sections - each Dendrite component has a
-# configuration section, in addition to the "global" section which applies to
-# all components.
-#
-# At a minimum, to get started, you will need to update the settings in the
-# "global" section for your deployment, and you will need to check that the
-# database "connection_string" line in each component section is correct.
-#
-# Each component with a "database" section can accept the following formats
-# for "connection_string":
-#   SQLite:     file:filename.db
-#               file:///path/to/filename.db
-#   PostgreSQL: postgresql://user:pass@hostname/database?params=...
-#
-# SQLite is embedded into Dendrite and therefore no further prerequisites are
-# needed for the database when using SQLite mode. However, performance with
-# PostgreSQL is significantly better and recommended for multi-user deployments.
-# SQLite is typically around 20-30% slower than PostgreSQL when tested with a
-# small number of users and likely will perform worse still with a higher volume
-# of users.
-#
-# The "max_open_conns" and "max_idle_conns" settings configure the maximum
-# number of open/idle database connections. The value 0 will use the database
-# engine default, and a negative value will use unlimited connections. The
-# "conn_max_lifetime" option controls the maximum length of time a database
-# connection can be idle in seconds - a negative value is unlimited.
