// when we make a new commit, we journal the inserts and removes.
// for each end_era that we journaled that we are no passing by,
// we remove all of its removes assuming it is canonical and all
// of its inserts otherwise.
// When we make a new commit, we make a journal of all blocks in the recent history and record
// all keys that were inserted and deleted. The journal is ordered by era; multiple commits can
// share the same era. This forms a data structure similar to a queue but whose items are tuples.
// By the time comes to remove a tuple from the queue (i.e. then the era passes from recent history
// into ancient history) then only one commit from the tuple is considered canonical. This commit
// is kept in the main backing database, whereas any others from the same era are reverted.
//
// We also keep reference counters for each key inserted in the journal to handle
// the following cases where key K must not be deleted from the DB when processing removals :
// Given H is the journal size in eras, 0 <= C <= H.
// Key K is removed in era A(N) and re-inserted in canonical era B(N + C).
// Key K is removed in era A(N) and re-inserted in non-canonical era B`(N + C).
// Key K is added in non-canonical era A'(N) canonical B(N + C).
// It is possible that a key, properly available in the backing database be deleted and re-inserted
// in the recent history queue, yet have both operations in commits that are eventually non-canonical.
// To avoid the original, and still required, key from being deleted, we maintain a reference count
// which includes an original key, if any.
//
// The semantics of the `counter` are:
// insert key k:
// counter already contains k: count += 1
// counter doesn't contain k:
// backing db contains k: count = 1
// backing db doesn't contain k: insert into backing db, count = 0
// delete key k:
// counter contains k (count is asserted to be non-zero):
// count > 1: counter -= 1
// count == 1: remove counter
// count == 0: remove key from backing db
// counter doesn't contain k: remove key from backing db
//
// Practically, this means that for each commit block turning from recent to ancient we do the
// following:
// is_canonical:
// inserts: Ignored (left alone in the backing database).
// deletes: Enacted; however, recent history queue is checked for ongoing references. This is
// reduced as a preference to deletion from the backing database.
// !is_canonical:
// inserts: Reverted; however, recent history queue is checked for ongoing references. This is
// reduced as a preference to deletion from the backing database.
// deletes: Ignored (they were never inserted).
//
// The counter is encreased each time a key is inserted in the journal in the commit. The list of insertions
// is saved with the era record. When the era becomes end_era and goes out of journal the counter is decreased
// and the key is safe to delete.
// record new commit's details.
