CommonCrawl.Parquet

English | 中文 | 日本語 | Français

A .NET library for reading Common Crawl index data stored in Parquet format. This library provides strongly-typed models and an efficient reader to process Common Crawl index records.

Features

  • Strongly Typed Models: Maps Common Crawl Parquet schema to the IndexTableRecord C# class.
  • Efficient Reading: Uses ParquetReader to read Parquet files asynchronously.
  • Filtering: Supports predicates to filter records while reading.

Installation

Install the package via NuGet:

NuGet

dotnet add package CommonCrawl.Parquet

Usage

You can use ParquetReader.Instance to read Parquet files. The reader returns an IAsyncEnumerable<T>, allowing for memory-efficient processing.

using CommonCrawl.Readers;
using CommonCrawl.Models;

// Read from a file path
var reader = ParquetReader.Instance;
string filePath = "path/to/cc-index.parquet";

await foreach (var record in reader.ReadAsAsyncEnumerable<IndexTableRecord>(filePath))
{
    Console.WriteLine($"URL: {record.Url}, Fetch Time: {record.FetchTime}");
}

// Read with a filter (e.g., only successful fetches)
await foreach (var record in reader.ReadAsAsyncEnumerable<IndexTableRecord>(filePath, r => r.FetchStatus == 200))
{
    Console.WriteLine($"Found valid URL: {record.Url}");
}

Models

IndexTableRecord

Represents a single record in the Common Crawl index. Key properties include:

  • Url: The full URL string.
  • UrlSurtKey: SURT URL key for canonicalization.
  • UrlHostName: Hostname of the URL.
  • FetchTime: Timestamp of the capture.
  • FetchStatus: HTTP status code.
  • ContentMimeType: MIME type of the content.
  • WarcFilename: Location of the WARC file in Common Crawl's S3 bucket.
  • WarcRecordOffset & WarcRecordLength: Position of the record in the WARC file.

For a full list of fields, refer to the source code or the Common Crawl Index Schema.
