getNonKeyAttributes

public List<String> getNonKeyAttributes()

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

The total count of attributes specified in 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.

Constraints:
Length: 1 - 20

Returns:

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

The total count of attributes specified in 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

public void setNonKeyAttributes(Collection<String> nonKeyAttributes)

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

The total count of attributes specified in 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.

Constraints:
Length: 1 - 20

Parameters:

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