# 批处理机
批处理处理器可用于聚合条目(日志/任何数据)并进行批处理。
当batch_max_size设置为零时处理器将立即执行每个条目。将批处理的最大大小设置为大于1将开始聚合条目直到达到最大大小或超时到期为止
## 构型
创建批处理程序的唯一必需参数是函数。当批处理达到最大大小或缓冲区持续时间超过时,将执行该功能。
|名称 |需求 |描述|
|------- |----- |------|
|id |可选的 |标识批处理者的唯一标识符|
|batch_max_size |可选的 |每批的最大大小默认为1000|
|inactive_timeout|可选的 |如果不活动将刷新缓冲区的最大时间以秒为单位默认值为5s|
|buffer_duration|可选的 |必须先处理批次中最旧条目的最大期限以秒为单位默认是5|
|max_retry_count|可选的 |从处理管道中移除之前的最大重试次数;默认为零|
|retry_delay |可选的 |如果执行失败应该延迟进程执行的秒数默认为1|
以下代码显示了如何使用批处理程序的示例。批处理处理器将要执行的功能作为第一个参数,将批处理配置作为第二个参数。
```lua
local bp = require("apisix.plugins.batch-processor")
local func_to_execute = function(entries)
-- serialize to json array core.json.encode(entries)
-- process/send data
return true
end
local config = {
max_retry_count = 2,
buffer_duration = 60,
inactive_timeout = 5,
batch_max_size = 1,
retry_delay = 0
}
local batch_processor, err = bp:new(func_to_execute, config)
if batch_processor then
batch_processor:push({hello='world'})
end
```
注意:请确保批处理的最大大小(条目数)在函数执行的范围内。
刷新批处理的计时器基于“ inactive_timeout”配置运行。因此为了获得最佳使用效果
保持“ inactive_timeout”小于“ buffer_duration”。
