DataKit 采集的数据结构定义

Point

Point 是 DataKit 中最常用的一种数据表示形式，目前 Point 有两种表现形式：

  1. 行协议
  2. Protobuf

由于行协议表达能力有限，后面会逐渐迁移到 Protobuf，同时中心仍然长期支持行协议写入（不同的 API 版本）。除此之外，行协议和 Protobuf 之间并无实质性的差异，效率上而言（非极端情况）：

  • 编码体积上，Protobuf 和航协议相当（随机出来的数据点）
  • 编码效率上，Protobuf 在效率（X10）和内存占用（X8）上，都较行协议更好
  • 解码效率上，Protobuf 也更好（X5）

以上测试，参见 TestEncodePayloadSize/BenchmarkEncode/BenchmarkDecode。 可参考如下结果：

Point 的约束

Point 构建函数：

pt := NewPointV2(name []byte, kvs KVs, opts... Option)

NewPoint() 已 Deprecated.

由于 Point 最终需要写入后端存储，故而受到后端存储的各种限制，但原则上采集端仍然做尽量少的限制，以保证数据采集的多样性和完整性。目前 Point 限制如下（本次放开/新加的约束，粗体表示）：

  1. 概念上，仍旧区分 tag 和 field。但在底层数据结构上，它们的类型一致，都是 key-value，只是在特定的 key-value 上，会标注其是否为 tag（IsTag）。可以简单理解为 tag/field 都是 key。field 概念不再重要，在这些 key-value 对中，tag 只是更特化的一种 key-value，非 tag 的 key-value 都可以视为 field。

  2. kvs 本质上是一个数组结构，以增加顺序排列

  3. 同一个 point 中，tag 和 field 之间不允许出现同名的 key。这一限制主要用来确保 DQL 查询时字段的唯一性。如果 tag/field 中出现同名 key，后出现的 key 将不再生效。

  4. tag/field key 以及 value 目前不做协议上的限制，这一限制可以在应用层（比如 datakit/kodo）通过 Option 配置来控制

  5. tag/field key/value 的内容均有几个方面的限制：

    • tag key 和 value 中均不允许出现换行字符，如果出现，SDK 会将其替换成空格。如字符串 "abc\ndef" 会被替换成 "abc def"。该限制无法通过 Option 控制。
    • Point 可以没有任何 key（即可以没有 tag 和 field）。对于这样的 point，在上传过程中，自动忽略，但不会影响其它正常 point 的处理。
    • tag key 和 value 均不允许以反斜杠 \ 结尾，如果出现，SDK 会将其移除掉。如字符串 "abc\" 会被替换成 "abc"。该限制无法通过 Option 控制。
    • 对日志类数据（非时序数据）而言，tag/field 的 key 中不允许出现 . 字符，如果出现，SDK 会将其替换成 _，如 key "abc.def" 会被替换成 "abc_def"。该限制可以通过 Option 控制。(注：这一限制主要因后端使用 ES 作为存储所致，如果不用 ES 可以移除这一限制)
    • tag/field 个数、 各个 tag/field key/value 长度（此处特指字符串长度）均可以通过 Option 设置。
    • 某些特定的数据类型（T/L/R/O/...），可以禁用某些 key（这里的 key 是带类型的，比如对象上不允许出现 key 为 class 的字段，一旦出现这些 key，最终的 Point 数据中，这些 key 将被自动移除掉。
      • 所有在构建点的过程中，如果出现自动调整（比如移除某些字段），均会在最终的 point 结构中出现对应的 warning 信息（通过 point.Pretty() 可以查看）

  6. 构建 point 过程中出现的 warning/debug 信息，如果用 PB 结构上报，会一并上传到中心（kodo），中心在写入存储的时候，可以不用理会这些信息，主要是调试用

  7. tag value 目前只支持 string 值

  8. field value 目前支持:

    • int8/int16/int32/int64 表示有符号整数
    • uint8/uint16/uint32/uint64 表示无符号整数
    • float64：浮点数，暂无限制
    • bool：暂无限制
    • []byte：字节流，可以存放二进制数据
    • string：暂无限制
    • []any：数组类型，数组元素必须是基础类型（int/uint/float/string/bool），且数组内类型一致。
