Hi is this a good flow? If no, then how would you improve? How i do it right now is by using nested try-catch.

try {
  // get the most recent created canister that will store the new data
  switch (database.getLatestCanister()) {
    case null throw Error.reject("No database canisters");
    case (?db) await db.save(data);
  }
} catch e1 {
  // no canisters? or latest db canister has reached size limit?
  // a new db canister is needed
  Cycles.add(1_000_000_000_000);
  let new_db = await Database.Canister();

  // track the new db canister
  let new_db_id = Principal.fromActor(new_canister);
  database.add(new_db_id); 

  // retry saving the new data
  try {
    await new_db.save(data);
  } catch e2 {
    // total fail: return e1 and e2 errors
  }
}
