表4 Quota

参数

参数类型

描述

user

String

用户名。

不对全部用户/客户端限流时,用户名和客户端ID不能同时为空。

client

String

客户端ID。

不对全部用户/客户端限流时,用户名和客户端ID不能同时为空。

  • 是,表示对全部用户限流。此时不能同时设置用户名。

  • 否,表示对特定用户限流。此时需要设置用户名。

client-default

Boolean

是否使用客户端默认设置。

  • 是,表示对全部客户端限流。此时不能设置客户端ID。

  • 否,表示对特定客户端限流。此时需要设置客户端ID。

producer-byte-rate

Long

生产上限速率(单位为B/s)。

consumer-byte-rate

Long

消费上限速率(单位为B/s)。

说明:

“生产上限速率”和“消费上限速率”不可同时为空。
