TODO:
- automated 'kill process' and 'power failure' test
- after rollback: is a regular save ok?
- cache: change API to better match guava / Android
- rename a map
- MVStore: improved API thanks to Simo Tripodi
- implement table engine for H2
- automated 'kill process' and 'power failure' test
- maybe split database into multiple files, to speed up compact
- auto-compact from time to time and on close
- test and possibly improve compact operation (for large dbs)
