### Purpose Noticed "large" autgenerated indices on blocks and blocklists in https://forum.syncthing.net/t/database-or-disk-is-full-might-be-syncthing-might-be-qnap/24930/7 They both have a primary key and don't need rowids ## Authorship Your name and email will be added automatically to the AUTHORS file based on the commit metadata.

-- Block lists
|
|
--
|
|
-- The block lists are extracted from FileInfos and stored separately. This
|
|
-- reduces the database size by reusing the same block list entry for all
|
|
-- devices announcing the same file. Doing it for all block lists instead of
|
|
-- using a size cutoff simplifies queries. Block lists are garbage collected
|
|
-- "manually", not using a trigger as that was too performance impacting.
