Amplitude Backfill Importer

This is a script to backfill data in an Amplitude project based on a project export. See https://amplitude.zendesk.com/hc/en-us/articles/206404358-Self-Data-Backfill-Guide for their primer on the subject.

It uses https://github.com/fmmfonseca/work_queue to manage a pool of workers making batch HTTP requests.

Usage

Prepare data

• Export the data you want to import from Amplitude's project detail pane
• Unzip the data file and concatenate it:

unzip -p <src>.zip | gunzip -c > <target>.json

Get an API key

• For the project you want to import to. It's recommended to run the import against a test project first (assuming you have the bandwidth under your monthly events cap)

Run the import

• Install dependencies:

bundle install

• Run the script:

API_KEY=<your API key> bundle exec ruby sample_import.rb <target>.json
