### 4. 多查询客户端的支持，0.0x毫秒级别的查询
|
||||
|

已经集成的客户端有：java, php, c, python，nodejs，php扩展(支持linux, php5, php7版本已支持)，golang。

已经集成的客户端有：java, C#, php, c, python，nodejs，php扩展(支持linux, php5, php7版本已支持)，golang。
|
||||
|
||||
提供了两种查询算法，响应时间如下：
|
||||
客户端/binary算法/b-tree算法/Memory算法：
|
||||
c#/0.x毫秒/0.x毫秒/0.x毫秒
|
||||
java/0.x毫秒/0.x毫秒/0.1x毫秒 (使用RandomAccessFile)
|
||||
php/0.x毫秒/0.1x毫秒/0.1x毫秒
|
||||
c/0.0x毫秒/0.0x毫秒/0.00x毫秒(b-tree算法基本稳定在0.02x毫秒级别)
