Functions to maintain taxonomy indexing.
Taxonomy uses default field storage to store canonical relationships between terms and fieldable entities. However its most common use case requires listing all content associated with a term or group of terms sorted by creation date. To avoid slow queries due to joining across multiple node and field tables with various conditions and order by criteria, we maintain a denormalized table with all relationships between terms, published nodes and common sort criteria such as status, sticky and created. When using other field storage engines or alternative methods of denormalizing this data you should set the taxonomy.settings:maintain_index_table to '0' to avoid unnecessary writes in SQL.
