7/ Autovacuum defaults are built for small tables. Default scale factor: vacuum when 20% of rows are dead. On a 100M-row table that's 20M dead tuples before it wakes up.
For hot tables: ALTER TABLE orders SET (autovacuum_vacuum_scale_factor = 0.01). Check n_dead_tup weekly.

vacuum cleans up dead rows. but only the ones no transaction could still see. one session left idle in transaction since lunch, and vacuum skips everything newer than it. autovacuum looks busy, the table keeps growing. check pg_stat_activity for old backend_xmin.

Autovacuum defaults scale off 20 percent of the table, so a 50M row table can pile up 10M dead tuples before it even starts. Per table autovacuum_vacuum_scale_factor fixes that for the hot ones.

Appending at 700 MB/s is the easy half. The number I'd want next is what retention does to it, since dropping old partitions is cheap and DELETE plus autovacuum at that rate is not.
