refactor(store/db): declare block_headers as WITHOUT ROWID#2238
Merged
Conversation
Remove unused indexes, redundant indexes and redundant columns from indexes.
Current key is BIGINT PRIMARY KEY, which in SQLite is not the special rowid alias. It therefore stores a hidden rowid plus a unique index on block_num. All current access is by block_num, latest ORDER BY block_num DESC LIMIT 1, IN, or full ordered scan.
