* The NDB engine global data.

Inside memcached, a pointer to this is treated as simply an ENGINE_HANDLE_V1
|
|
pointer. But inside the NDB engine that pointer is cast up to point to the
|
|
whole private structure.
|
|
|
|
This structure also contains a pointer to the default engine's
|
|
private structure, since all caching is delegated to the default
|
|
engine.
