The following sections describe how to access and understand the files found in a data feed delivery.

Access data feed content

To access the contents of a data feed:

  1. Log in to the data feed destination site.

    This is the destination site that you set up when creating the data feed, such as an Amazon S3 or Google Cloud Platform bucket.

  2. Download the compressed data feed file to your local machine.

  3. Unzip the compressed file using a program that supports .tar.gz file extensions.

  4. Open the hit_data.tsv file in your spreadsheet or database application of choice to see raw data for that day. -->

Manifest file feed-manifest

The manifest file contains the following details about each file that is part of the uploaded data set:

  • File name
  • File size
  • MD5 hash
  • Number of records contained in the file

The manifest file follows the same format as a Java JAR manifest file.

The manifest file is always delivered last as a separate .txt file, so that its existence indicates that the complete data set for that request period has already been delivered. Manifest files are named according to the following:

[rsid]_[YYYY-mm-dd].txt

A typical manifest file contains data similar to the following:

Datafeed-Manifest-Version: 1.0
 Lookup-Files: 1
 Data-Files: 1
 Total-Records: 611

 Lookup-File: rsid_date-lookup_data.tar.gz
 MD5-Digest: af6de42d8b945d4ec1cf28360085308
 File-Size: 63750

 Data-File: 01-rsid_date.tsv.gz
 MD5-Digest: 9c70bf783cb3d0095a4836904b72c991
 File-Size: 122534
 Record-Count: 611

Every manifest file contains a header, indicating the total number of lookup files, data files, and total number of records in all data files. This header is followed by multiple sections containing information for each file included in the data feed delivery.

Some feeds are configured to receive a .fin file instead of a .txt manifest. The .fin indicates that the upload is complete, but the metadata that it contains is in an older format.

Lookup files

Some data feed columns output a number that corresponds to its actual value. Lookup files are used to match a number from a data feed column and match it to an actual value. For example, a value of 鈥497鈥 in the browser hit data column indicates that the hit came from 鈥淢icrosoft Internet Explorer 8鈥 if you look in browser.tsv.

Note that the column_headers.tsv and event_list.tsv are specific to the data feed and report suite. Other files, such as browser.tsv, are generic.

The lookup files are delivered together in a compressed zip named according to the following:

[rsid]_[YYYY-mm-dd]-lookup_data.[compression_suffix]
  • column_headers.tsv: A single row containing the column headers for hit_data.tsv.
  • browser.tsv: Maps the browser ID (the browser feed column) to the browser鈥檚 friendly name.
  • browser_type.tsv: Maps the browser ID (the browser feed column) to the browser type.
  • color_depth.tsv: Maps the color depth ID (the color feed column) to color depth.
  • connection_type.tsv: Maps the connection type ID (the connection_type feed column) to the connection type.
  • country.tsv: Maps the country ID (the country feed column) to the country name.
  • javascript_version.tsv: Maps the JavaScript version ID (the javascript feed column) to the JavaScript version.
  • languages.tsv: Maps the language ID (the language feed column) to language.
  • operating_systems.tsv: Maps the operating system id (the os feed column) to the operating system name.
  • plugins.tsv: Maps the plug-in ID鈥檚 (the plugin feed column) to each respective plug-in name.
  • resolution.tsv: Maps the resolution ID (the resolution feed column) to the monitor resolution.
  • referrer_type.tsv: Maps the referrer type ID (the ref_type feed column) to the referrer type.
  • search_engines.tsv: Maps the search engine ID (the search_engine feed column) to the search engine name.
  • event.tsv: Maps each event ID (the event_list feed column) to its respective event name.

Hit data files

Hit data is provided in a hit_data.tsv file. The amount of data in this file is determined by the delivery format (hourly or daily, and single or multiple files). This file contains only hit data. The column headers are delivered separately with the lookup files. Each row in this file contains a single server call.

Files delivered by 蜜豆视频 vary based on the type of data feed that you have configured. All files are encoded using ISO-8859-1.

  • [rsid] refers to the report suite ID the data feed is from.
  • [index] is used only in multiple file feeds, and refers to the correct order of paginated files.
  • [YYYY-mm-dd] refers to the starting day the data feed is for.
  • [HHMMSS] is used only in hourly feeds, and refers to the starting hour the data feed is for.
  • [compression_suffix] refers to the type of compression used. Typically data feeds are compressed into tar.gz or zip files.
  • [format_suffix] refers to the type of file format. Typically data feed file format is .tsv.

Daily, single file

After data is collected for a day, you receive a single compressed data file and a manifest file. The data file is named:

[rsid]_[YYYY-mm-dd].[compression_suffix]

When extracted, the data file contains a single hit_data.tsv file with all data for that day, as well as lookup files for any required columns.

Daily, multiple files

After data is collected for a day, you receive one or more compressed data files and a manifest file. The data file is named:

[index]-[rsid]_[YYYY-mm-dd].[compression_suffix]

When extracted, each data file contains a single [index]-[rsid]_[YYYY-mm-dd].[format_suffix] that contains approximately 2GB of uncompressed data, as well as lookup files for any required columns.

Hourly, single file

After data is collected for an hour, you receive a single compressed data file and a manifest file. The data file is named:

[rsid]_[YYYYmmdd]-[HHMMSS].[compression_suffix]

When extracted, the data file contains a single hit_data.tsv file with all data for that hour, as well as lookup files for any required columns.

Hourly, multiple files

After data is collected for an hour, you receive one or more compressed data files and a manifest file. The data files are named:

[index]-[rsid]_[YYYYmmdd]-[HHMMSS].[format_suffix].[compression_suffix]

When extracted, each data file contains a single [index]-[rsid]_[YYYYmmdd]-[HHMMSS].[format_suffix] file that contains approximately 2GB of uncompressed data, as well as lookup files for any required columns.

Data file size

The hit data file size varies greatly depending on the number of variables actively used and amount of traffic sent to report suite. However, on average, a row of data is approximately 500B (compressed) or 2KB (uncompressed). Multiplying this by the number of server calls can provide a rough estimate on how large a data feed file is. Once your organizations starts receiving data feed files, you can find a more accurate number by dividing the number of rows in hit_data.tsv by its total file size.
