constexpr uint32_t | FSP_HEADER_OFFSET = FIL_PAGE_DATA |
Offset of the space header within a file page. More... | |
constexpr uint32_t | FSP_SDI_HEADER_LEN = 8 |
The number of bytes required to store SDI root page number(4) and SDI version(4) at Page 0. More... | |
constexpr uint32_t | FSP_SPACE_ID = 0 |
space id More... | |
constexpr uint32_t | FSP_NOT_USED = 4 |
this field contained a value up to which we know that the modifications in the database have been flushed to the file space; not used now More... | |
constexpr uint32_t | FSP_SIZE = 8 |
Current size of the space in pages. More... | |
constexpr uint32_t | FSP_FREE_LIMIT = 12 |
Minimum page number for which the free list has not been initialized: the pages >= this limit are, bydefinition, free; note that in a single-table tablespace where size < 64 pages, this number is 64, i.e.,we have initialized the space about the first extent, but have not physically allocated those pages to thefile.
