<div class="block">An ORCv2 file writer. The file is divided into stripes, which is the natural
 unit of work when reading. Each stripe is buffered in memory until the
 memory reaches the stripe size and then it is written out broken down by
 columns. Each column is written by a TreeWriter that is specific to that
 type of column. TreeWriters may have children TreeWriters that handle the
 sub-types. Each of the TreeWriters writes the column's data as a set of
 streams.
 <p>
 This class is unsynchronized like most Stream objects, so from the creation
 of an OrcFile and all access to a single instance has to be from a single
 thread.
 <p>
 There are no known cases where these happen between different threads today.
 <p>
 Caveat: the MemoryManager is created during WriterOptions create, that has
 to be confined to a single thread as well.</div>
