pub async fn composite_index_max_attributes(t: &mut Test) -> Result<()>Expand description
Maximum attribute boundary: #[index(partition = [f1, f2, f3, f4], local = [f5, f6, f7, f8])] (DDB-only).
DynamoDB allows up to 4 HASH + 4 RANGE attributes in a GSI KeySchema.
Verifies that setup_db() succeeds at the limit and that a query using all
4 partition key attributes returns correct results.
