Robert Fratto	f2fc0c26c2	chore(dataobj): column building (#15634) ... This commit adds the ability to accumulate sequences of dataset.Value into a column, which is split up across multiple pages. Each page is broken down into two parts: * A bitmap-encoded sequence of booleans, where 1 indicates a row has a value and 0 indicates the row is NULL, and * the encoded sequence of non-NULL values, whose encoding is determined by the column options. The sequence of non-NULL values is then optionally compressed. This commit also includes initial support for reading these columns, starting with internal-only helper utilities for unit tests.	1 year ago
