Updated by Luke Murphey almost 12 years ago
Updated by Might want to index:
- Division::descriptor (to improve performance of get_division)
- Division::sequence_number (since this is sorted to find the first chapter)
- Verse::indicator (since a search is done on this field when a verse is highlighted)
- Division::readable_unit (since get_chapter_for_division does a query on this field)

Updated by Luke Murphey almost 12 years ago
Indexing Division::descriptor improved get_division from about 0.0040 seconds to 0.0025:
create index "reader_division_descriptor" ON "reader_division" ("descriptor")
Indexing the sequence number didn't seem to do too much:
create index "reader_division_sequence_number" ON "reader_division" ("sequence_number")
Indexing readable_unit did seem to improved performance (from 0.012 to 0.004 seconds):
create index "reader_division_readable_unit" ON "reader_division" ("readable_unit")
Indexing verse indicators did not seem to do much if anything even for the performance of queries looking for a particular verse:
create index "reader_verse_indicator" ON "reader_verse" ("indicator")
