Ensure complete retrieval of keys when using Redis SCAN command.

          **Ensure complete retrieval of keys when using Redis SCAN command.**

The current usage of redis.scan may not retrieve all matching keys, as SCAN is a cursor-based iterator that requires looping until the cursor returns zero. The scan command fetches a subset of keys per call and provides a cursor for the next set.

Consider modifying the code to iterate over the cursor to collect all matching keys:

let cursor = 0;
const hashKeys: string[] = [];

do {
  const reply = await redis.scan(cursor, { MATCH: 'hash:*' });
  cursor = reply.cursor;
  hashKeys.push(...reply.keys);
} while (cursor !== 0);

const hashes = hashKeys.map((hash) => hash.substring(5));

This ensures that all matching keys are retrieved. Alternatively, if the number of keys is expected to be small, you might consider organizing your data differently in Redis to allow more efficient retrieval.
