Big Data Processing Toolkit
Overview
大数据团队核心处理工具集,包含高性能DataFrame库和分布式计算框架。
Quick Reference
| 工具 | 场景 | 数据规模 |
|---|---|---|
| Polars | 单机高性能分析 | GB级 |
| Dask | 分布式/超内存处理 | TB级 |
| Vaex | 超大文件惰性处理 | 100GB+ |
选择指南
数据大小判断:
├── < 10GB → Polars (最快)
├── 10GB - 100GB → Polars (streaming) 或 Dask
├── > 100GB → Dask (分布式)
└── 超大单文件 → Vaex (内存映射)
任务类型:
├── 简单ETL → Polars
├── 复杂管道 → Dask
├── 交互分析 → Vaex
└── 机器学习 → Dask + Dask-ML

常用模式
ETL Pipeline (Polars)
import polars as pl
# 读取 -> 转换 -> 写入
(
pl.scan_csv("raw/*.csv")
.filter(pl.col("status") == "valid")
.with_columns(
pl.col("amount").cast(pl.Float64),
pl.col("date").str.to_datetime()
)
.group_by("category")
.agg(pl.col("amount").sum())
.collect()
.write_parquet("output/summary.parquet")
)
分布式处理 (Dask)
import dask.dataframe as dd
from dask.distributed import Client
client = Client() # 启动本地集群
ddf = dd.read_parquet("data/*.parquet")
result = ddf.groupby("key").agg({"value": "sum"}).compute()
超大文件分析 (Vaex)
import vaex
df = vaex.open("huge_file.hdf5") # 不加载到内存
df.mean(df.column) # 惰性计算
性能最佳实践
- 文件格式: Parquet > CSV (10x faster)
- 惰性计算: 使用
scan_*而非read_* - 列选择: 尽早选择需要的列
- 分区策略: 按日期/类别分区大数据集
- 并行度: CPU核心数 = 并行任务数

是什么
Big Data Processing Toolkit 用来把 数据分析师 场景里的任务输入转成可执行的流程、检查清单和交付物。

它的价值在于让 数据AI职能线 在 Claude Code、Codex、Gemini、Hermes 或 OpenClaw 中复用同一套岗位能力,而不是依赖一次性的聊天提示词。
怎么用
- 明确当前任务目标、输入材料、约束和期望交付物,再加载
bigdata-core。 - 按 skill 文档中的流程、检查清单或工具建议执行,优先复用仓库已有规范与真实命令。
- 把关键判断、风险、验证命令和产出路径记录到当前任务文档或交付说明中。
- 用最小可证明的检查确认结果有效;发现缺口时回到 skill 清单补齐。
