Classes
struct	ddl::file_t
	Information about temporary files used in merge sort. More...

struct	ddl::Fetch_sequence
	Fetch the document ID from the table. More...

struct	ddl::Row
	Physical row context. More...

Namespaces
namespace	ddl
	The general architecture is that the work is done in two phases, roughly the read and write phase.

Typedefs
using	ddl::IO_buffer = std::pair< byte *, os_offset_t >
	Block size for DDL I/O operations. More...

using	ddl::Latch_release = std::function< dberr_t()>
	Called when a log free check is required. More...

using	ddl::Builders = std::vector< Builder , ut::allocator< Builder > >

using	ddl::Merge_offsets = std::deque< os_offset_t, ut::allocator< os_offset_t > >
	Start offsets in the file, from where to merge records. More...

Functions
bool	ddl::file_create (file_t file, const char path) noexcept
	Create a merge file int the given location. More...

dberr_t	ddl::pwrite (os_fd_t fd, void *ptr, size_t size, os_offset_t offset) noexcept
	Write a merge block to the file system. More...

dberr_t	ddl::pread (os_fd_t fd, void *ptr, size_t len, os_offset_t offset) noexcept
	Read a merge block from the file system. More...

Variables
static constexpr size_t	ddl::SERVER_CLUSTER_INDEX_ID = 0
	Cluster index ID (always the first index). More...
