Include dependency graph for sequential_id.hpp:

This graph shows which files directly or indirectly include this file:

Classes
struct	foedus::storage::sequential::HeadPagePointer
	Each pointer to a snapshot head page comes with a bit more information to help reading. More...

Namespaces
	foedus
	Root package of FOEDUS (Fast Optimistic Engine for Data Unification Services).

	foedus::storage
	Storage Manager, which implements a couple of key/value stores.

	foedus::storage::sequential
	Sequential Storage, an append/scan only data structure.

Functions
void	foedus::storage::sequential::get_pointer_page_and_index (uint16_t thread_id, uint16_t page, uint16_t index)
	Calculate the page/index of the thread-private head/tail pointer. More...

Variables
const uint16_t	foedus::storage::sequential::kMaxSlots = 1 << 15
	We have to represent the record count in 15 bits. More...

const uint16_t	foedus::storage::sequential::kHeaderSize = 64
	Byte size of header in each data page of sequential storage. More...

const uint16_t	foedus::storage::sequential::kDataSize = foedus::storage::kPageSize - kHeaderSize
	Byte size of data region in each data page of sequential storage. More...

const uint16_t	foedus::storage::sequential::kMaxPayload = kDataSize
	Payload must be shorter than this length. More...

const uint16_t	foedus::storage::sequential::kRootPageHeaderSize = 56
	Byte size of header in each root page of sequential storage. More...

const uint16_t	foedus::storage::sequential::kRootPageMaxHeadPointers = (foedus::storage::kPageSize - kRootPageHeaderSize) / sizeof(HeadPagePointer)
	Maximum number of head pointers in one root page. More...

const uint16_t	foedus::storage::sequential::kRootPageDataSize = foedus::storage::kPageSize - kRootPageHeaderSize
	Byte size of data region in each root page of sequential storage. More...

const uint16_t	foedus::storage::sequential::kPointerPageCount = 1U << 6
	Each poiner page can contain 2^10 pointers (as the node is implicit, PagePoolOffset suffices) and we can have at most 2^16 cores. More...

const uint16_t	foedus::storage::sequential::kPointersPerPage = 1U << 10
