/*! @page tune_bulk_load Bulk-load

When loading a large amount of data into a new object, using a cursor
with the \c bulk configuration string enabled and loading the data in
sorted order will be much faster than doing out-of-order inserts.

WiredTiger cursors can be configured for bulk-load using the \c bulk
configuration keyword to WT_SESSION::open_cursor.  Bulk-load is a "fast
path" for quickly loading a large number of rows.  Bulk-load may only
be used on newly created objects, and an object being bulk-loaded is not
accessible from other cursors.

Cursors configured for bulk-load only support the WT_CURSOR::insert and
WT_CURSOR::close methods.  Bulk load inserts are non-transactional: they
cannot be rolled back and ignore the transactional state of the WT_SESSION
in which they are opened.

When doing a bulk-load insert, keys must be inserted in sorted order.
When doing a bulk-load insert into a column-store object, any skipped
records will be created as already-deleted rows. If a column-store
bulk-load cursor is configured with \c append, the cursor key will be
ignored and each inserted row will be assigned the next sequential
record number.

When using the \c sort utility on a Linux or other POSIX-like system to
pre-sort keys, the locale specified by the environment affects the sort
order and may not match the default sort order used by WiredTiger.  Set
\c LC_ALL=C in the process' environment to configure the traditional sort
order that uses native byte values.

When bulk-loading fixed-length column store objects, the \c bulk
configuration string value \c bitmap allows chunks of a memory resident
bitmap to be loaded directly into an object by passing a WT_ITEM to
WT_CURSOR::set_value, where the size field indicates the number of
records in the bitmap (as specified by the object's \c value_format
configuration). Bulk-loaded bitmap values must end on a byte boundary
relative to the bit count (except for the last set of values loaded).
