charset

◆ doc_stats

ib_vector_t* fts_index_cache_t::doc_stats

Array of the fts_doc_stats_t contained in the memory buffer.

Must be in sorted order (ascending). The ideal choice is an rb tree but the rb tree imposes a space overhead that we can do without

que_t** fts_index_cache_t::ins_graph

Insert query graphs.

◆ sel_graph

que_t** fts_index_cache_t::sel_graph

Select query graphs.
