So the total size isn’t nearly as much of an issue as with hashmap heads. And if it’s 8GB for the full chain is then pretty reasonable, like the prevout cache. Ordering is the next big consideration. A block of filters can be created once all previous blocks are populated, same as validate, so I previously moved this aspect into the validation stage. The filter heads must be computed in order by block, like confirmation, so this was split into an independent table and integrated into the confirmation chaser.
