Previously, multiple frames with different prefixes were used to separate different data layouts. This included separating standard row/column layouts from inverted column/row layouts as well as storing aggregate information for timestamp data. Unfortunately, this caused frame meta data to be copied between multiple frames and it made it difficult to keep these frames in sync. This commit separates these different physical layouts into `Views`. A `Frame` now has one or more views which represent each layout. Fragments have been moved from under the `Frame` to be contained within the `View`. There are two primary views: - `standard` - `inverse` If a frame has a time quantum, then views are generated for these each of the standard/inverse views. For example a time quantum of `YMDH` for the date `2000-01-02T00:00:00Z` would create the following views: - `standard_2000` - `inverse_2000` - `standard_200001` - `inverse_200001` - `standard_20000102` - `inverse_20000102` From the user's perspective, nothing should change in PQL. Different PQL statements will handle the appropriate view automatically. For example, `Bitmap()` and `Profile()` will fetch using the `standard` view or the `inverse` view, respectively. The `Range()` statement will lookup the appropriate time-based views automatically. |
