As you said, RCU and WCU measures the number of reads and writes (respectively) per second. However, for obvious reasons, doing a 10 byte read is not billed the same as a read of the entire database - one RCU is a read of up to 4KB, and larger reads are counted as multiple reads. WCU uses a smaller quantum (1KB).

No matter the size of your database or the number of concurrent queries, DynamoDB aims to provide the same single-digit millisecond response time for all operations.

To configure auto scaling in DynamoDB, you set the minimum and maximum levels of read and write capacity in addition to the target utilization percentage. Auto scaling uses Amazon CloudWatch to monitor a table’s read and write capacity metrics. To do so, it creates CloudWatch alarms that track consumed capacity.This may enable faster scans, but you'll still be limited in time and payload size so it's still problematic for huge table scans. Summary. DynamoDB enforces paginating results (max 1MB) AppSync limits payload size (max 1MB, less if you're going to use subscriptions too) DynamoDB Scans are less efficient than queries.Amazon DynamoDB currently limits the size of each item that you store in a table (see Service, account, and table quotas in Amazon DynamoDB ).If the total number of scanned items exceeds the maximum data set size limit of 1 MB, the scan stops and results are returned to the user as a LastEvaluatedKey value to continue the scan in a subsequent operation.

That means if all items in your table are 400KB in size each (the max per item) and you set the limit parameter to 5, you will always get at most 2 items from the table, because of the 1MB limit.

The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. To have DynamoDB return fewer items, you can provide a FilterExpression operation. If the total size of scanned items exceeds the maximum dataset size limit of 1 MB, the scan completes and results are returned to the user. Request format. The DynamoDB low-level API accepts HTTP(S) POST requests as input. The AWS SDKs construct these requests for you. Suppose that you have a table named Pets, with a key schema consisting of AnimalType (partition key) and Name (sort key). Both of these attributes are of type string.To retrieve an item from Pets, the AWS SDK constructs the following request.The maximum item size in DynamoDB is 400 KB. This limit includes attribute name binary length (UTF-8 encoded) and attribute value lengths (again binary length). Large items might also use up your provisioned throughput more quickly, so you must factor this into your capacity planning if your workload has large items.Data files. DynamoDB can export your table data in two formats: DynamoDB JSON and Amazon Ion. Regardless of the format you choose, your data will be written to multiple compressed files named by the keys. These files are also listed in the manifest-files.json file.Some of the limits are: There are more than 25 requests in the batch. Any individual item in a batch exceeds 400 KB.
