 @NotNull ComposableTableReplayConfiguration defaultConfiguration)

Apply the given default configuration to this configuration; and return a possibly new configuration representing this configuration with the defaults.

Parameters:

defaultConfiguration - the default configuration

Returns:

this configuration merged with the default configuration's values for undefined properties
