class Aws::DynamoDB::Types::Projection
Represents attributes that are copied (projected) from the table into an index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.
@note When making an API call, you may pass Projection
data as a hash: { projection_type: "ALL", # accepts ALL, KEYS_ONLY, INCLUDE non_key_attributes: ["NonKeyAttributeName"], }
@!attribute [rw] projection_type
The set of attributes that are projected into the index: * `KEYS_ONLY` - Only the index and primary keys are projected into the index. * `INCLUDE` - In addition to the attributes described in `KEYS_ONLY`, the secondary index will include other non-key attributes that you specify. * `ALL` - All of the table attributes are projected into the index. @return [String]
@!attribute [rw] non_key_attributes
Represents the non-key attribute names which will be projected into the index. For local secondary indexes, the total count of `NonKeyAttributes` summed across all of the local secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total. @return [Array<String>]
