Two types of indexes are supported by Amazon DynamoDB.

They are:

Global Secondary index :

It is an index with a partition or a partition sort key that is different from those on the table. The global secondary index is CONSIDERED to be global because queries on the index can span all the items in a table, ACROSS all the partitions.

LOCAL secondary index :

An index that has the same partition key as that of the table but different sort key. It is considered to be “local” because every partition of the index is SCOPED to a table partition that has the same partition key.
