Class Summary

Class	Description
ArrowReader	Vectorized reader that returns an iterator of ColumnarBatch.
ArrowVectorAccessor<DecimalT,Utf8StringT,ArrayT,ChildVectorT extends java.lang.AutoCloseable>
BaseBatchReader<T>	A base BatchReader class that contains common functionality
ColumnarBatch	This class is inspired by Spark's ColumnarBatch.
ColumnVector	This class is inspired by Spark's ColumnVector.
GenericArrowVectorAccessorFactory<DecimalT,Utf8StringT,ArrayT,ChildVectorT extends java.lang.AutoCloseable>	This class is creates typed ArrowVectorAccessor from VectorHolder.
NullabilityHolder	Instances of this class simply track whether a value at an index is null.
VectorHolder	Container class for holding the Arrow vector storing a batch of values along with other state needed for reading values out of it.
VectorHolder.ConstantVectorHolder<T>	A Vector Holder which does not actually produce values, consumers of this class should use the constantValue to populate their ColumnVector implementation.
VectorHolder.DeletedVectorHolder
VectorHolder.PositionVectorHolder
VectorizedArrowReader	VectorReader(s) that read in a batch of values into Arrow vectors.
VectorizedArrowReader.ConstantVectorReader<T>	A Dummy Vector Reader which doesn't actually read files, instead it returns a dummy VectorHolder which indicates the constant value which should be used for this column.
VectorizedArrowReader.DeletedVectorReader	A Dummy Vector Reader which doesn't actually read files.
VectorizedReaderBuilder
VectorizedTableScanIterable	A vectorized implementation of the Iceberg reader that iterates over the table scan.
