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.

Member Data Documentation

ulint fts_cache_t::added

Number of doc ids added since last optimized. This variable is covered by the deleted lock

Definition at line 186 of file fts0types.h.

mem_heap_t* fts_cache_t::cache_heap

Cache Heap

Definition at line 191 of file fts0types.h.

ulint fts_cache_t::deleted

Number of doc ids deleted since last optimized. This variable is covered by deleted_lock

Definition at line 182 of file fts0types.h.

ib_vector_t* fts_cache_t::deleted_doc_ids

Array of deleted doc ids, each element is of type fts_update_t

Definition at line 146 of file fts0types.h.

ib_mutex_t fts_cache_t::deleted_lock

Lock covering deleted_doc_ids

Definition at line 142 of file fts0types.h.

ib_mutex_t fts_cache_t::doc_id_lock

Lock covering Doc ID

Definition at line 144 of file fts0types.h.

doc_id_t fts_cache_t::first_doc_id

first doc id since this table was opened

Definition at line 179 of file fts0types.h.

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

Definition at line 154 of file fts0types.h.

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

Definition at line 149 of file fts0types.h.

rw_lock_t fts_cache_t::init_lock

lock used for the cache intialization, it has different SYNC level as above cache lock

Definition at line 136 of file fts0types.h.

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

Definition at line 132 of file fts0types.h.

doc_id_t fts_cache_t::next_doc_id

Next doc id

Definition at line 175 of file fts0types.h.

ib_mutex_t fts_cache_t::optimize_lock

Lock for OPTIMIZE

Definition at line 140 of file fts0types.h.

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

Definition at line 169 of file fts0types.h.

fts_stopword_t fts_cache_t::stopword_info

Cached stopwords for the FTS

Definition at line 190 of file fts0types.h.

fts_sync_t* fts_cache_t::sync

sync structure to sync data to disk

Definition at line 161 of file fts0types.h.

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

Definition at line 163 of file fts0types.h.

doc_id_t fts_cache_t::synced_doc_id

Doc ID sync-ed to CONFIG table

Definition at line 177 of file fts0types.h.

ulint fts_cache_t::total_size

total size consumed by the ilist field of all nodes. SYNC is run whenever this gets too big

Definition at line 158 of file fts0types.h.
