getNonKeyAttributes
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.
- Returns:
- 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.
-
setNonKeyAttributes
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.
- Parameters:
nonKeyAttributes
- 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.
-
withNonKeyAttributes
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.
NOTE: This method appends the values to the existing list (if any). Use
setNonKeyAttributes(java.util.Collection)
orwithNonKeyAttributes(java.util.Collection)
if you want to override the existing values.- Parameters:

If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
- Returns:
- Returns a reference to this object so that method calls can be chained together.
