// Compact will create a copy of the source DB and in the destination DB. This may
// reclaim space that the source database no longer has use for. txMaxSize can be
// used to limit the transactions size of this process and may trigger intermittent
// commits. A value of zero will ignore transaction sizes.
// TODO: merge with: https://github.com/etcd-io/etcd/blob/b7f0f52a16dbf83f18ca1d803f7892d750366a94/mvcc/backend/backend.go#L349
