Detailed Description

Compressed list of words that have been read from FTS INDEX that needs to be optimized.

Member Data Documentation

block_sz

ulint fts_zip_t::block_sz

Size of a block in bytes.

blocks

ib_vector_t* fts_zip_t::blocks

Vector of compressed blocks.

heap_alloc

ib_alloc_t* fts_zip_t::heap_alloc

Heap to use for allocations.

index_scan_complete

bool fts_zip_t::index_scan_complete

Did the last pass compress all remaining words in index?

last_big_block

ulint fts_zip_t::last_big_block

Offset of last block in the blocks array that is of size block_sz.

Blocks beyond this offset are of size FTS_MAX_WORD_LEN

max_words

ulint fts_zip_t::max_words

Maximum number of words to read in one pass.

n_words

ulint fts_zip_t::n_words

Number of words compressed.

pos

ulint fts_zip_t::pos

Offset into blocks.

status

lint fts_zip_t::status

Status of (un)/zip operation.

word

fts_string_t fts_zip_t::word

The value of the last word read from the FTS INDEX table.

This is used to discard duplicates (UTF-8 string)

zp

z_streamp fts_zip_t::zp

ZLib state.
