💡 Hint

Common Mistakes

Confusing bytes with kilobytes or megabytes.

Using 4000 bytes which is too small for DynamoDB items.

DynamoDB limits each item to a maximum size of 400 KB (409,600 bytes).

💡 Hint

Common Mistakes

Confusing 400 KB with 1 MB or 10 MB limits.

Assuming the limit is larger than it actually is.

The correct maximum item size is 400 KB, not 1 MB or larger.

4fill in blank

hard

Fill both blanks to complete the explanation about item size considerations.

DynamoDB

💡 Hint

Common Mistakes

Using incorrect size limits like 1 MB.

Ignoring large attribute handling.

The item size limit is 400 KB. Compressing large attributes helps stay within this limit.

5fill in blank

hard

Fill all three blanks to complete the code snippet about item size and attribute handling.

DynamoDB

If an item exceeds [1], consider [2] data into smaller items or using [3] to reduce size.

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Ignoring the size limit or using wrong values.

Choosing 'ignoring' as a strategy.

Items larger than 400 KB should be split or compressed to fit DynamoDB limits.
