/**
* An extremely minimal and lightweight {@code HistoricalTimeSeriesSource} that pulls data
* directly from Redis for situations where versioning, multiple fields, multiple data sources,
* and identifier management is not necessary.
* <p>
* The following constraints must hold for this Source to be of any utility whatsoever:
* <ul>
* <li>Historical lookups are not required. Because they are not supported.</li>
* <li>Version corrections are not required. Because they are not supported.</li>
* <li>Each time series has a <b>single</b> {@link ExternalId} which then acts
* as the {@link UniqueId} internally.</li>
* <li>Each external ID has a single time series (thus there is not the capacity to store
* different Data Source, Data Provider, Observation Time, Data Field series).</li>
* </ul>
* <p>
* Where a method is not supported semantically, an {@link UnsupportedOperationException}
* will be thrown. Where use indicates that this class may be being used incorrectly,
