• Guests per Invitation: 100 guests
• RSVP Responses: 100 responses per invitation
• Event Details: Each invitation includes 5 details (venue, date, etc.)

Data Breakdown

User Data:

• Size per user: 2 KB
• Total: 1000 * 2 KB = 2 MB

Invitation Data:

• Size per invitation: 10 KB
• Total: 1000 * 10 KB = 10 MB

Guest Data:

• Size per guest: 1 KB
• Total: 1000 * 100 * 1 KB = 100 MB

RSVP Data:

• Size per response: 0.5 KB
• Total: 1000 * 100 * 0.5 KB = 50 MB

Event Details:

• Size per detail: 0.2 KB
• Total: 1000 * 5 * 0.2 KB = 1 MB

Total Data Starting Usage:

2 MB (User Data) + 10 MB (Invitation Data) + 100 MB (Guest Data) + 50 MB (RSVP Data) + 1 MB (Event Details) = 163 MB
