DynamoDB Errors and Exceptions - Running List

Will add errors and exceptions that I come across here.

LimitExceededException

The number of concurrent table requests (cumulative number of tables in the CREATING, DELETING or UPDATING state) exceeds the maximum allowed of 10.

Also, for tables with secondary indexes, only one of those tables can be in the CREATING state at any point in time. Do not attempt to create more than one such table simultaneously.

The total limit of tables in the ACTIVE state is 250.

ProvisionedThroughputExceededException

Your request rate is too high.

The AWS SDKs for DynamoDB automatically retry requests that receive this exception.

Your request is eventually successful, unless your retry queue is too large to finish.

Reduce the frequency of requests and use exponential backoff. 

If you're not exceeding your table's read capacity throughput, you may be exceeding an individual partition's capacity throughput. DynamoDB distributes capacity evenly across all available partitions. If a given partition is consuming more than its share of throughput, this error can be raised.
