This [data stream](../../datastreams/data-streams-introduction) handles Fitbit sensor data downloaded using the [Fitbit Web API](https://dev.fitbit.com/build/reference/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 parsed sensor data in a MySQL database, RAPIDS can process it.
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.
The `format.yaml` maps and transforms columns in your raw data stream to the [mandatory columns RAPIDS needs for Fitbit sensors](../mandatory-fitbit-format). This file is at:
If you want to use this stream with your data, modify every sensor in `format.yaml` to map all columns except `TIMESTAMP` in `[RAPIDS_COLUMN_MAPPINGS]` to 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.
`add_zero_timestamp` adds an all-zero column called `timestamp` that will be filled in later in the pipeline by `readable_time.R` converting LOCAL_DATE_TIME to a unix timestamp taking into account single or multiple time zones.

Fitbit API has two versions for sleep data, v1 and v1.2. We support both but ignore v1's `count_awake`, `duration_awake`, and `count_awakenings`, `count_restless`, `duration_restless` columns.
