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. Also, if the processed data set size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey to apply in a subsequent operation to continue the operation. For more information, see Query and Scan in the Amazon DynamoDB Developer Guide. Constraints:The actual reads and writes performance of your DynamoDB tables may vary and may be ... say, 80 items will exceed provisioned throughput (with the size of each item less than 4 KB and a total size of all ... will be additionally charged as provisioned read capacity overuse because provisioned capacity is basically a method to limit read/write ...Feb 28, 2020 · When you exceed RCUs (3000) or WCUs (1000) limits for a single partition When DynamoDB sees a pattern of a hot partition, it will split that partition in an attempt to fix the issue.

Quite an old question. Since then AWS has clarified how DynamoDB computes the storage size per item type.

Numbers are variable length, with up to 38 significant ... DynamoDB adaptive capacity responds by increasing partition 4's capacity so that it can sustain the higher workload of 150 WCU/sec without being throttled. Isolate frequently accessed items If your application drives disproportionately high traffic to one or more items, adaptive capacity rebalances your partitions such that frequently accessed items don't …DynamoDB limits the size of each item you can store in a table. If you need to store more data than the limit permits, you can compress the data using common algorithms such as GZIP. It lets you store more data and reduce storage costs. Store large attributes in Amazon S3If 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 ...

Sep 12, 2017 · The internal hash function of DynamoDB ensures data is spread evenly across available partitions. This simple mechanism is the magic behind DynamoDB's performance. Limits of a partition. The partition can contain a maximum of 10 GB of data. With size limit for an item being 400 KB, one partition can hold roughly more than 25000 (=10 GB/400 KB ... 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.Some of the limits are: There are more than 25 requests in the batch. Any individual item in a batch exceeds 400 KB. The total request size exceeds 16 MB. The big unknown for me is how is possible with 25 items of a maximum of 400 Kb, the payload will exceed 16Mbs. Accounting for table names of less than 255 bytes, etc. ….
