class	CompressedColumnarLongsSupplier
class	CompressedLongsSerializer
class	CompressedVariableSizedBlobColumnSerializer
class	CompressedVSizeColumnarIntsSerializer Streams array of integers out in the binary format described by CompressedVSizeColumnarIntsSupplier
class	CompressedVSizeColumnarIntsSupplier
class	CompressedVSizeColumnarMultiIntsSupplier Format - byte 1 - version offsets - ColumnarInts of length num of rows + 1 representing offsets of starting index of first element of each row in values index and last element equal to length of values column, the last element in the offsets represents the total length of values column.
class	EncodedStringDictionaryWriter
class	EntireLayoutColumnarDoublesSerializer Serializer that produces EntireLayoutColumnarDoublesSupplier.EntireLayoutColumnarDoubles.
class	EntireLayoutColumnarFloatsSerializer Serializer that produces EntireLayoutColumnarFloatsSupplier.EntireLayoutColumnarFloats.
class	EntireLayoutColumnarLongsSerializer Serializer that produces EntireLayoutColumnarLongsSupplier.EntireLayoutColumnarLongs.
class	FixedIndexedIntWriter Specialized version of FixedIndexedWriter for writing ints, with no support for null values, and no verification that data is actually sorted, it just trusts you and takes your word for it
class	FixedIndexedWriter<T> Writer for a FixedIndexed
class	FrontCodedIndexedWriter DictionaryWriter for a FrontCodedIndexed, written to a SegmentWriteOutMedium.
class	GenericIndexed<T> A generic, flat storage mechanism.
class	GenericIndexedWriter<T> Streams arrays of objects out in the binary format described by GenericIndexed The version EncodedStringDictionaryWriter.VERSION is reserved and must never be specified as the GenericIndexed version byte, else it will interfere with string column deserialization.
