DRILL-336: Modified the netty direct memory manager to:
1) Efficiently reduce ("trim") the size of a memory buffer, releasing the extra memory back to the memory manager.
2) Opportunistically allocate larger buffers if it can be done efficiently.
3) Raise a warning exception if resizing a buffer copies more than 1 page of data.
4) Added Javadocs and some in-code comments.
5) Created a Junit test to verify basic functionality.
The "trim" and allocation changes are primarily in PoolChunkL,
which breaks a "chunk" into runs of pages using a buddy system.
Take advantage of memory interface changes.

+ * A Chunk is a large, fixed size piece of memory allocated from the operating system.
+ * This PoolChunk allocator divides a chunk into a run of pages using the buddy system.

+ *
+ * This allocator does "normal" allocations, where the requested size varies
+ * from page size to chunk size.
+ *
+ * The allocator is based on buddy system. It views a chunk as a binary tree with
+ * 1 run of chunksize, or
+ * 2 runs of chunksize/2, or
+ * 4 runs of chunksize/4, or
+ * ...
+ * 2^maxOrder runs of pagesize
+ *
+ * Each node in the binary tree is labeled:
+ * - unused. The node and all its children are unallocated
+ * - allocated. The node (and all its children) are allocated
+ * as a single request. The children remain marked "unused".
+ * - branch. At least one descendent is allocated.
+ *
+ * The binary tree is represented in the "memoryMap",
+ * which saves the node status in a simple array without using links.
+ * The array indices indicate the position within the tree as follows:
+ * 0 - unused
+ * 1 - root
+ * 2,3 - children of 1
+ * 4,5 6,7 - children of 2 and 3
+ * 8,9 10,11 12,13 14,15 - next level of children.

+ * i*2 points to left child, i*2+1 points to right child.

+ * Note the current code also deals with smaller subpage allocations.
+ * The overall memory manager only comes here when it wants a new page,

+/**
+* This package implements a memory manager for off-heap data based on pools and arenas.
+* It is derived from the netty memory manager with the following changes:
+* - Classes have been redefined to store data little-endian. (Append "L" to class names)
+* - A "trim" method has been added to reduce a buffer's maxCapacity and free the extra memory.
+* - allocate(min, max)
+*
+* This manager is based on the following memory abstractions:
+* - a "chunk" is a piece of memory allocated from the operating system,
+* - a "page" is is a piece of memory allocated from a chunk, and
+* - an "element" is a piece of memory allocated from a page.
+*
+* This memory manager classifies the memory request according to the size of requested memory.
+* - "subpage" memory manager which breaks a page into equal sized elements.
+* It uses a bitmap to indicate which ones are free. (why not linked list?)
+* - "normal" memory manager which breaks a chunk into runs of pages.
+* Management is done using the "buddy system", so each run is a power-of-2 pages.
+* - "huge" memory manager which allocates memory larger than a chunk.
+* It goes straight to the operating system.
+*
+* The PoolArena utilizes these three memory managers, trying to minimize fragmentation
+* in the big buffers while keeping good performance for the small buffers.
+*
+* The three submanagers are:
+* subpage allocations. A page is divided into equal sized elements with a bitmask indicating
+* which elements are free. The page is placed into a pool (linked list)
+* according to the size of the elements.
+* Normal allocations. A chunk is divided into multiple pages according to the buddy system.
+* Chunks are kept in a list partially ordered to minimize fragmentation.
+* Huge allocations. Memory larger than a chunk is allocated directly from the OS.
+*
+* To avoid contention, there are multiple "arenas" rather than a single monolithic memory manager.
+* Threads are assigned to an arena on a round-robin basis, and a buffer is always returned
+* to the arena of its origin.
+*
+*
+* Note for "normal" allocations: Rather than keeping one fully ordered list of chunks,
+* it keeps several lists, and always
+* searches the first list, followed by the next list. Thus it achieves an approximate ordering without
+* having to do a full sort.
+*
+*
+* This PoolArena allocator is configured according to Java environment variables.
+* io.netty.allocator.numDirectArenas - the number of arenas to divide among threads.
+* io.netty.allocator.pageSize - The size of each page, must be power of 2.
+* io.netty.allocator.maxOrder - Specifies chunkSize as pageSize * 2^maxOrder.
+*
+* It may not make sense to use this allocator for small allocations.
+* Each buffer which is allocated uses a Java class which must also be allocated.
+* Thus we may not save on Java memory management for small buffers.

Posted by ja...@apache.org.
Drill-400 change parquet reader to place varbinary fields into VarCharVectors, allowing them to be returned by default as UTF-8 Strings. Note that this will only be the case with newer parquet files that were produced after Converted Types were added to the format. This metadata stores the desired intrepertation of a column, but was not originally in the format. For older files you will still need to case binary data to Varchar.
