Minimizing Hello World example (disk space, ...)

[jcalfee]

Could you please direct me on how I might adjust the Hello World to have a small but operational foot-print?

The most obvious thing was the 1.2 Gigs of disk space used by 4 nodes right after start-up. Each of the 4 nodes takes up over 250MB and that must be the reason why it give me a sluggish first-impression.

Maybe it is simply adding a few parameters here and re-compiling?

dragonboat-example/helloworld/main.go

Lines 156 to 157 in d343e50

	// See GoDoc for all available options
	rc := config.Config{

I'm not sure how to apply this though. It does not compile when I try these settings below in the config block above.

// GetTinyMemLogDBConfig returns a LogDB config aimed for minimizing memory
// size. When using the returned config, LogDB takes up to 256MBytes memory.
func GetTinyMemLogDBConfig() LogDBConfig {
	cfg := getDefaultLogDBConfig()
	cfg.KVWriteBufferSize = 4 * 1024 * 1024
	cfg.KVMaxWriteBufferNumber = 4
	return cfg
}

GetTinyMemLogDBConfig

Maybe add a link for this: "See GoDoc for all available options"

Thank you!
