the ratio is 1:5

Data storage

long url :100 byte

short url: 8 byte

created_at time : 8 byte

user_id: 20 byte

expiration_time 8 byte

144 byte per entry for simplicity it could be around 256 byte

Daily Data Generation

if you assume you handle 200 requests per second to create new short URLs, and considering that there are 86,400 seconds in a day, the total data generated daily would be:

200 requests/second * 86,400 seconds/day * 256 bytes = 4.4 GB/day.

Long-term Data Growth:
- If this pattern continues, over five years, the total data generated might be approximately 8 TB or more, considering growth, yielding about 15 TB of total data including some buffer.
