• Follows work and research described in: https://docs.google.com/document/d/1l6uXIjTPHOOWM5N4sUUmUfCZvePoa5SNfIEtmgvgQSU/edit#heading=h.7l0i621y5vgm
• Current working tree: https://github.com/cosmos/iavl/tree/v2-alpha6

1 folder per module prefix, each with 2 databases, changelog.db and tree.db. storekey defaults to “root” for a single tree implementation.

receive changeset, write leaves to leaf table in changelog.db, always. this table contains a btree index. the writes are append only on the end.
