fitbitparsed_mysql

This data stream handles Fitbit sensor data downloaded using the Fitbit Web API, parsed, and stored in a MySQL database. Please note that RAPIDS cannot query the API directly, you need to use other available tools or implement your own. Once you have your sensor data in a MySQL database, RAPIDS can process it.

!!! info "What is the difference between JSON and plain data streams" Most people will only need fitbitjson_mysql because they downloaded and stored their data directly from Fitbit's API. However, if for some reason you don't have access to that JSON data and instead only have the parsed data (columns and rows) you can use this data stream.

Container

A MySQL database with a table per sensor, each containing the data for all participants.

The script to connect and download data from this container is at:

src/data/streams/fitbitjson_mysql/container.R

Format

The format.yaml maps and transforms columns in your raw data stream to the mandatory columns RAPIDS needs for Fitbit sensors. This file is at:

src/data/streams/fitbitparsed_mysql/format.yaml

If you want RAPIDS to process Fitbit sensor data using this stream, you will need to replace any COLUMN_MAPPINGS inside each sensor section in format.yaml to match your raw data column names.

All columns are mandatory, however, all except device_id and local_date_time can be empty if you don't have that data. Just have in mind that some features will be empty if some of these columns are empty.
