The following are some general principles and design patterns to keep in mind when creating indexes in DynamoDB: Use indexes efficiently. Choose projections carefully. Optimize frequent queries to avoid fetches. Be aware of item-collection size limits when creating local secondary indexes. DynamoDB with boto3 - limit acts as page size. According to the boto3 docs, the limit argument in query allows you to to limit the number of evaluated objects in your DynamoDB table/GSI. However, LastEvaluatedKey isn't returned when the desired limit is reached and therefore a client that would like to limit the number of fetched results will ...The result set from a Scan is limited to 1 MB per call. You can use the LastEvaluatedKey from the scan response to retrieve more results. The use case is unclear why you wanted to get all 3000 records in one scan.

We are introducing native support for document model like JSON into DynamoDB, the ability to add / remove global secondary indexes, adding more flexible scaling options, and increasing the item size limit to 400KB. These improvements have been sought by many applications ...Part 2) Since we have constraing regarding the pictures (size between 300KB and 5MB), we can't memorize those information on DynamoDB, because the limit for each row in DynamoDB is 400KB even if we don't have this constraint, it is better to memorize the uploaded pictures on a permanent storage rather than the DB. That's why it's better to use S3.An individual record in DynamoDB is called an item, and a single DynamoDB item cannot exceed 400KB. While 400KB is large enough for most normal database operations, it is significantly lower than the other options. MongoDB allows for documents to be 16MB, while Cassandra allows blobs of up to 2GB.Amazon DynamoDB is based on the principles of Dynamo, a progenitor of NoSQL, and brings the power of the cloud to the NoSQL database world. It offers customers high-availability, reliability, and incremental scalability, with no limits on dataset size or request throughput for a given table.

Whenever DynamoDB compares binary values, it treats each byte of the binary data as unsigned. The length of a binary attribute can be zero, if the attribute is not used as a key for an index or table, and is constrained by the maximum DynamoDB item size limit of 400 KB. DynamoDB has a size limit of 400 KB for each item. This limit includes both attribute name (binary length with UTF-8 encoding) and attribute value (again binary length).
