DynamoDB Deep Dive: NoSQL for Software Engineers

# Size limit
We can't have an item bigger than 400 KB in a DynamoDB table. However, we can have as many items as we want in a table.

# Attribute names
Attribute names like `Book_id` are stored within attributes and are therefore counted towards an item's size. Therefore, we should use short, intuitive attribute names to keep item sizes low. For example, "BkId" would be a good attribute name for `Book_id` because it is short but informative.
# Compressed attributes
Sometimes, there are larger attributes, such as in the case of a Facebook post. To save the text of the post, we will need a lot of storage space, probably a few tens of KB. To use a minimal amount of this space, we can save the text of the post in a compressed format. We can use GZIP for compressing our attribute values.
# Dividing Items
we can also divide bigger items into smaller items wherever there is a one-to-many relationship.
