Read the Directory: - * - Fetch the list of keys in the directory, sorted by their timestamp in descending order—newest to oldest. - * - * 2. Initialize a Skip List: - * - Create an empty set data structure to keep track of the parent nodes that can be skipped. - * - * 3. Iterate through Keys: - * - Start from the newest key and move towards the oldest. - * - If the key is in the skip list, skip the read and continue. - * - Read the node and add its parents to the skip list. - * - * 4. Idempotent Application: - * - Apply the nodes to your DAG. Given that your application is idempotent, there's no harm in reapplying nodes, - * but the skip list should minimize this. - * - * 5. State Tracking: - * - Keep track of the oldest key you've successfully processed. This becomes the starting point for your next read, - * adjusted for the safety window. - * - * 6. Retry Logic: - * - If a key is missing, you could either skip it (since the system is designed to be eventually consistent) or - * implement some kind of retry logic. - * - * By implementing this algorithm, we aim to minimize the number of reads and work with the most current snapshot - * of the data. It also avoids the need to delete keys, thereby averting the read-modify-write race condition. - * - * Writes: https://chat.openai.com/share/5dd42b0e-cbb8-4006-823b-7269df05e9eb * * @param params - The parameters for the download, including the name and branch. * @returns - Returns the metadata bytes as a Uint8Array or null if the fetch is unsuccessful.
