"""
Retrieving data requires a stream name, a start datetime, and an end
datetime. Note that an `ID_FIELD` and `@TIMESTAMP_FIELD` field are
attached to each event. The `ID_FIELD` is a UUID1-style identifier
with its time bits derived from the timestamp. This allows event IDs
to be roughly sortable by the time that they happened while providing
a deterministic tiebreaker when two events happened at the same time.
