Which of the following solutions is not supported by DynamoDB:
Correct Answer:A
In DynamoDB, a secondary index is a data structure that contains a subset of attributes from a table, along with an alternate key to support Query operations. DynamoDB supports the following two types of secondary indexes:
Local secondary index is an index that has the same hash key as the table, but a different range key. A local secondary index is "IocaI" in the sense that every partition of a local secondary index is scoped to a table partition that has the same hash key.
Global secondary index is an index with a hash and range key that can be different from those on the table. A global secondary index is considered "gIobaI" because queries on the index can span all of the data in a table, across all partitions.
