Understanding Cost Drivers in Supabase

Which of the following is the primary factor that increases your monthly cost when using Supabase?

A Increasing the number of database rows stored

B Increasing the number of API requests made

C Increasing the number of users logged in simultaneously

D Increasing the number of tables created

💡 Hint

Think about what Supabase charges for most directly.

Supabase pricing is mainly influenced by the number of API requests made, as each request consumes resources and bandwidth.

Optimizing Storage Costs in Supabase

You want to reduce storage costs in Supabase without losing data. Which approach is best?

A Delete all data older than 1 month

B Keep all data in Supabase but compress it automatically

C Archive old data to external storage and remove it from Supabase

D Create more tables to split data

💡 Hint

Think about moving data you don't need often to cheaper storage.

Archiving old data to external storage reduces Supabase storage usage and cost while preserving data.

Cost Impact of Security Misconfigurations

Which security misconfiguration in Supabase can indirectly increase your costs?

A Using strong passwords for all users

B Restricting API keys to specific IP addresses

C Enabling multi-factor authentication

D Allowing public access to your database without restrictions

💡 Hint

Consider what happens if unauthorized users access your resources.

Public access can lead to abuse, causing excessive API requests and data usage, increasing costs.

Efficient API Usage to Reduce Costs

Which practice helps reduce API request costs in Supabase?

A Batch multiple operations into a single API request

B Poll the database every second for changes

C Make separate API requests for each small operation

D Use unlimited API keys for all users

💡 Hint

Think about how to reduce the number of calls made.

Batching operations reduces the total number of API requests, lowering costs.

Analyzing Cost Behavior with Realtime Subscriptions

What happens to your Supabase cost if you open many realtime subscriptions without closing unused ones?

A Costs increase due to continuous data streaming and resource usage

B Costs remain the same because subscriptions are free

C Costs increase only if you exceed storage limits

D Costs decrease because data is cached locally

💡 Hint

Consider how open connections affect resource consumption.

Open realtime subscriptions consume resources continuously, increasing costs.
