application.db is growing too quickly

[CharlieMc0]

application.db seems to be growing too quickly.

It's currently 29GB in size.

29G	./application.db
1.3G	./snapshots
2.7G	./blockstore.db
3.8G	./state.db
22G	./tx_index.db
36K	./evidence.db
1021M	./cs.wal
59G	.

The /home/zetachain/.zetacored/data directory has grown by about 55GB in the last 30 days even with pruning turned on. That'll be 660GB/year if growth continues at this pace.
