Overview
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"],
}
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.
Instance Attribute Summary collapse
-
#non_key_attributes ⇒ Array<String>
Represents the non-key attribute names which will be projected into the index.
-
#projection_type ⇒ String
The set of attributes that are projected into the index:.
Instance Attribute Details
#non_key_attributes ⇒ Array<String>
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
-
If you project the same attribute into two different indexes,
this counts as two distinct attributes when determining the total.

#projection_type ⇒ String
The set of attributes that are projected into the index:
-
‘KEYS_ONLY` - Only the index and primary keys are projected into the index.
-
‘INCLUDE` - Only the specified table attributes are projected into the index. The list of projected attributes are in `NonKeyAttributes`.
-
