Instance Attribute Details

#non_key_attributes ⇒ Array<String>^? (readonly)

Represents the non-key attribute names which will be projected into the index.

For global and local secondary indexes, the total count of NonKeyAttributes summed across all of the secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total. This limit only applies when you specify the ProjectionType of INCLUDE . You still can specify the ProjectionType of ALL to project all attributes from the source table, even if the table has more than 100 attributes.

Returns:

• (Array<String>, nil)

def non_key_attributes
  @non_key_attributes
end

#projection_type ⇒ String^? (readonly)

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.

When using the DynamoDB console, ALL is selected by default.

Returns:

• (String, nil)
