AI-generated Key Takeaways
-
A LocalBucket represents a time interval for aggregated data, like a user's step count over an hour or day.
-
Each bucket includes a start time, an end time, and the aggregated data sets for the requested data types within that interval.
-
The TYPE_TIME constant indicates that bucketing is requested by time.
A bucket represents a time interval over which aggregated data is computed. For example, a bucket can represent user's step count over a 1 hour interval. We allow buckets to be computed by time, where a time bucket can represent a full day, hour, or any other desired interval.
A bucket consists of the following fields:
-
startTimedenotes the start time of the bucket. This field is always present. -
endTimedenotes the end time of the bucket. This field is always present. -
dataSetsLocalDataSetfor the aggregatedLocalDataTyperequested in the read query over the time interval of this bucket.
