as3 集群节点数 最大 32
as4 集群节点数 最大 8


max Number of sets per namespace       1023
maximum number of bins per namespace   32,767


max number of namespace    Enterprise(32)   Community(2)

Objects per Namespace per Node    32 Billion  / 4 Billion 

社区版  Namespace 记录数  40亿

The maximum number of devices (or files) per namespace per node is 128 as of version 4.2, 
64 for versions down to 3.12.1, and 32 for versions prior to that.

集群节点数限制
For Community Edition, the maximum number of nodes is limited to 31 for versions prior to 4.0 
and limited to 8 for versions 4.0 and above.


单个记录数大小限制
Every record value size is limited to the write-block-size, 
which is typically set in the configuration to 128KB for Flash devices, 
but can be increased up to 8MiB as of version 4.2 
(for prior versions, maximum is 1MiB which is also the default if not specified in the configuration file).

默认1M


Note that you can have more than one SSD associated with a namespace, 
but any SSD used as a raw device can only be associated with a single namespace. 
Each namespace is limited to a maximum of 128 devices

一个namespace可以关联多个SSD,
使用裸设备,一个 namespace只能关联一个设备
单个namespace最多 128个设备
