+// A key column from probe side of the join can be matched against a key column from build
+// side of the join, as long as the underlying value types are equal. That means that:
+// - both scalars and arrays can be used and even mixed in the same column
+// - dictionary column can be matched against non-dictionary column if underlying value

+// - dictionary column can be matched against dictionary column with a different index

+// We currently require in hash join that for all dictionary encoded columns, the same

+// index types, and dictionary key against non-dictionary key, internally comparisons will
+// be evaluated after remapping values on both sides of the join to a common
+// representation (which will be called "unified representation"). This common
+// representation is a column of int32() type (not a dictionary column). It represents an
+// index in the unified dictionary computed for the (only) dictionary present on build
+// side (an empty dictionary is still created for an empty build side). Null value is
+// always represented in this common representation as null int32 value, unified
+// dictionary will never contain a null value (so there is no ambiguity of representing
+// nulls as either index to a null entry in the dictionary or null index).
+//
+// Unified dictionary represents values present on build side. There may be values on

+///
+/// This operation is sometimes also referred to as UNPIVOT
+///
+/// This is typically done when there are multiple observations in each row in order to
+/// transform to a table containing a single observation per row.
+///
+/// For example:
+///
+/// | time | left_temp | right_temp |
+/// | ---- | --------- | ---------- |
+/// | 1    | 10        | 20         |
+/// | 2    | 15        | 18         |
+///
+/// The above table contains two observations per row.  There is an implicit feature
+/// "location" (left vs right) and a measurement "temp".  What we really want is:
+///
+/// | time | location | temp |
+/// | ---  | ---      | ---  |
+/// | 1    | left     | 10   |
+/// | 1    | right    | 20   |
+/// | 2    | left     | 15   |
+/// | 2    | right    | 18   |
+///
+/// For a more complex example consider:
+///
+/// | time | ax1 | ay1 | bx1 | ay2 |
+/// | ---- | --- | --- | --- | --- |
+/// | 0    | 1   | 2   | 3   | 4   |
+///
+/// We can pretend a vs b and x vs y are features while 1 and 2 are two different
+/// kinds of measurements.  We thus want to pivot to
+///
+/// | time | a/b | x/y |  f1  |  f2  |
+/// | ---- | --- | --- | ---- | ---- |
+/// | 0    | a   | x   | 1    | null |
+/// | 0    | a   | y   | 2    | 4    |
+/// | 0    | b   | x   | 3    | null |
+///
+/// To do this we create a row template for each combination of features.  One should
+/// be able to do this purely by looking at the column names.  For example, given the
+/// above columns "ax1", "ay1", "bx1", and "ay2" we know we have three feature
+/// combinations (a, x), (a, y), and (b, x).  Similarly, we know we have two possible
+/// measurements, "1" and "2".
+///
+/// For each combination of features we create a row template.  In each row template we
+/// describe the combination and then list which columns to use for the measurements.
+/// If a measurement doesn't exist for a given combination then we use nullopt.
+///
+/// So, for our above example, we have:
+///
+/// (a, x): names={"a", "x"}, values={"ax1", nullopt}
+/// (a, y): names={"a", "y"}, values={"ay1", "ay2"}
+/// (b, x): names={"b", "x"}, values={"bx1", nullopt}
+///
+/// Finishing it off we name our new columns:
+/// feature_field_names={"a/b","x/y"}
+/// measurement_field_names={"f1", "f2"}

+///    ranges according to parameters (see constructor).
+///
+///    By default, the cache will also start fetching the combined ranges in parallel in
+///    the background, unless CacheOptions.lazy is set.
+///
+/// 2. Call WaitFor() to be notified when the given ranges have been read. If
+///    CacheOptions.lazy is set, I/O will be triggered in the background here instead.
+///    This can be done in parallel (e.g. if parsing a file, call WaitFor() for each
+///    chunk of the file that can be parsed in parallel).
+///
+/// 3. Call Read() to retrieve the actual data for the given ranges.
+///    A synchronous application may skip WaitFor() and just call Read() - it will still
