#include <fts0types.h>
Detailed Description
The cache for the FTS system. It is a memory-based inverted index
that new entries are added to, until it grows over the configured maximum size, at which time its contents are written to the INDEX table.
Field Documentation
| ulint fts_cache_t::added |
Number of doc ids added since last optimized. This variable is covered by the deleted lock
| mem_heap_t* fts_cache_t::cache_heap |
Cache Heap
| ulint fts_cache_t::deleted |
Number of doc ids deleted since last optimized. This variable is covered by deleted_lock
| ib_vector_t* fts_cache_t::deleted_doc_ids |
Array of deleted doc ids, each element is of type fts_update_t
| ib_mutex_t fts_cache_t::deleted_lock |
Lock covering deleted_doc_ids
| ib_mutex_t fts_cache_t::doc_id_lock |
Lock covering Doc ID
| doc_id_t fts_cache_t::first_doc_id |
first doc id since this table was opened
| ib_vector_t* fts_cache_t::get_docs |
information required to read the document from the table. Each element is of type fts_doc_t
| ib_vector_t* fts_cache_t::indexes |
We store the stats and inverted index for the individual FTS indexes in this vector. Each element is an instance of fts_index_cache_t
| rw_lock_t fts_cache_t::init_lock |
lock used for the cache intialization, it has different SYNC level as above cache lock
| rw_lock_t fts_cache_t::lock |
lock protecting all access to the memory buffer. FIXME: this needs to be our new upgrade-capable rw-lock
| doc_id_t fts_cache_t::next_doc_id |
Next doc id
| ib_mutex_t fts_cache_t::optimize_lock |
Lock for OPTIMIZE
| ib_alloc_t* fts_cache_t::self_heap |
This heap is the heap out of which an instance of the cache itself was created. Objects created using this heap will last for the lifetime of the cache
| fts_stopword_t fts_cache_t::stopword_info |
Cached stopwords for the FTS
| fts_sync_t* fts_cache_t::sync |
sync structure to sync data to disk
| ib_alloc_t* fts_cache_t::sync_heap |
The heap allocator, for indexes and deleted_doc_ids, ie. transient objects, they are recreated after a SYNC is completed
| doc_id_t fts_cache_t::synced_doc_id |
Doc ID sync-ed to CONFIG table
| ulint fts_cache_t::total_size |
total size consumed by the ilist field of all nodes. SYNC is run whenever this gets too big
