Ludvig Strigeus uttered:

Assuming I have an autovacuum database that primarily stores 32k blobs. If I
add/remove lots of rows, will this lead to excessive fragmentation of the
overflow chains, or does Sqlite do anything to try to unfragment the pages
belonging to a single row?


I believe auto-vacuum will simply shuffle data so as to compact free space, rather than ordering table and overflow data into contiguous regions. Hence, you'll still have fragmentation.



Thanks,
Ludvig
