CompareRowNumbers compares the sequences of row numbers in a and b for partial equality, descending from top-level through the given definition level.

EmptyRowNumber creates an empty invalid row number.

MaxRowNumber is a helper that represents the maximum(-ish) representable value.

ColumnIterator asynchronously iterates through the given row groups and column.

DictionaryPredicateHelper is a helper for a predicate that uses a dictionary for filtering.

Generic predicate with callbacks to evalulate data of type T Fn evalulates a single data point and is required.

IntBetweenPredicate checks for int between the bounds [min,max] inclusive.

IteratorResult is a row of data with a row number and named columns of data.

JoinIterator joins two or more iterators for matches at the given definition level.

KeyValueGroupPredicate takes key/value pairs and checks if the group contains all of them.

iterator - Every iterator follows this interface and can be composed.

Predicate is a pushdown predicate that can be applied at the chunk, page, and value levels.

RowNumber is the sequence of row numbers uniquely identifying a value in a tree of nested columns, starting at the top-level and including another row number for each level of nesting.
