MdbmDistSupport::Distributer.new do |m|
  m.lock_path     = '/tmp/hoge.lck'
  m.meta_path     = '/tmp/hoge_meta.mdbm'
  m.local_path    = '/tmp/hoge_local.mdbm'
  m.dist_path     = '/tmp/hoge_dist.mdbm'
  m.cmd_print     = '/tmp/print.rb'
  m.cmd_gen       = :mdbm_store_func
  m.cmd_rep       = '/usr/local/bin/mdbm_replace'
  m.full_mode     = true
  m.dist_servers  =
  [
    'host' => 'remote1', 'port' => 22, 'user' => 'foo', 'key' => '/home/foo/.ssh/id_rsa',
    'host' => 'remote2', 'port' => 22, 'user' => 'hee', 'key' => '/home/hee/.ssh/id_rsa',
    'host' => 'remote3', 'port' => 22, 'user' => 'hyo', 'key' => '/home/hyo/.ssh/id_rsa',
  ]
end.run_dist

settings @run_dist

name value memo
lock_path lock file path
meta_path meta mdbm path
local_path mdbm path
dist_path mdbm path in remote dist_server_hosts
cmd_print print command path need to make
cmd_gen generate mdbm command path or :mdbm_store_func need to make if you want to generate mdbm othert than String:String set like int64:String, int32:int64.if you set :mdbm_store_func only, set use mdbm.stroe() function.
cmd_rep replace mdbm command path mdbm_replace
full_mode true: full false: inc when you set false, distribute when meta_mdbm_increment_key key in meta was updated only.
dist_servers distribute server info array

require 'mdbm_dist_support'

puts "1111111\tFUGAFUGA"
inc_val = '2017-09-09 11:11:11'

MdbmDistSupport::Distributer.new do |m|
  m.meta_path = '/tmp/hoge_meta.mdbm'
end.run_print_after(inc_val)

settings @run_print_after

name value
meta_path meta mdbm path
