Where in ~/.bitcoin are mempool and UTXO pools written? Where in ~/.bitcoin are the two pools in question stored when their size grows above the size set by dbcache and maxmempool in bitcoin.conf.
Is UTXO pool written to such location at Bitcoin Core's shutdown?
mempool.dat stores the obvious, but it it only written there when the node is shut down
chainstate/ stores the entire UTXO, all the time
