Calculating throughput capacity!
Read capacity units
- 1 strong consistent read per second up to 4 KB item
- 2 eventually consistent reads per second up to 4 KB item
Write capacity unit
- 1 write per second for an item up to 1 KB in size
Example: 1000 writes per 10 seconds @ 512 bytes evenly distributed.
Solution: 1000\10 = 100, 512 bytes rounded up = 1 KB, 100 write units
Good certification exam information… 🙂
