The capacity consumed depends on the size of the items, and how many of them are accessed (I say accessed because if you have filters in place, more capacity may be consumed than the number of items actually returned would consume if there are items that get filtered out) to produce the results returned.

0.5 represents the default read rate, meaning that AWS Glue will attempt to consume half of the read capacity of the table. If you increase the value above 0.5, AWS Glue increases the request rate; decreasing the value below 0.5 decreases the read request rate. (The actual read rate will vary, depending on factors such as whether there is a uniform key …DynamoDB charges for data you export based on the size of each DynamoDB table (table data, local secondary indexes, and global secondary indexes) at the specified point in time when the backup was created. ¥ 0.88000 per GB; Additional charges apply for storing exported data in Amazon S3 and for PUT requests made against your Amazon S3 bucket.Before you start connection to DynamoDB , you need to have some table created in AWS.

With pagination, the Query results are divided into "pages" of data that are 1 MB in size (or less). An application can process the first page of results, then the second page, and so on. A single Query only returns a result set that fits within the 1 MB size limit. To determine whether ... Earlier, we saw how DynamoDB limits the result size from a Query or Scan operation to 1MB of data. But what happens if your operation has more than 1MB of data?
