+//   - InternalServerError

+//     For most purposes, up to 500 simultaneous table operations are allowed per
+//     account. These operations include CreateTable, UpdateTable, DeleteTable,UpdateTimeToLive,

+//
+//     When you are creating a table with one or more secondary indexes, you can
+//     have up to 250 such requests running at a time. However, if the table or
+//     index specifications are complex, then DynamoDB might temporarily reduce
+//     the number of concurrent operations.
+//
+//     When importing into DynamoDB, up to 50 simultaneous import table operations
+//     are allowed per account.
 //
-//   - ResourceNotFoundException
-//     The operation tried to access a nonexistent table or index. The resource
-//     might not be specified correctly, or its status might not be ACTIVE.
+//     There is a soft account quota of 2,500 tables.

-//   - ItemCollectionSizeLimitExceededException
-//     An item collection is too large. This exception is only returned for tables
-//     that have one or more local secondary indexes.
+//     GetRecords was called with a value of more than 1000 for the limit request

 //
-//   - TransactionConflictException
-//     Operation was rejected because there is an ongoing transaction for the item.
+//     More than 2 processes are reading from the same streams shard at the same
+//     time. Exceeding this limit may result in request throttling.
