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'

| 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 |
