A FilterExpression is applied after the items have already been read; the process of filtering does not consume any additional read capacity units. Note that some DynamoDB actions can take two kinds of expression; for example, UpdateItem can have both a ConditionalExpression and UpdateExpression, while Scan can have both a FilterExpression and ProjectionExpression, so the Add*Expression() functions need to share the ExpressionAttributeNames and ExpressionAttribute values query attributes. For example, equals, greater than, less than, etc. They are from open source Python projects.
