-Querying this structure requires using the [`indexOf`](/sql-reference/functions/array-functions#indexofarr-x) function to identify the index of the required key (which should be consistent with the order of the values). This can be used to access the values array column i.e. `values[indexOf(keys, 'status')]`. We still require a JSON parsing method for the request column - in this case, `simpleJSONExtractString`.

 A typical design pattern in ClickHouse is to use the [`groupArray`](/sql-reference/aggregate-functions/reference/grouparray) aggregate function to (temporarily) transform specific row values of a table into an array. This then can be conveniently processed via array functions, and the result can be converted back into individual table rows via [`arrayJoin`](/sql-reference/functions/array-join) aggregate function.
 
-Because ClickHouse SQL supports [higher order lambda functions](/sql-reference/functions/overview#arrow-operator-and-lambda), many advanced array operations can be achieved by simply calling one of the higher order built-in array functions, instead of temporarily converting arrays back to tables, as it is often [required](https://cloud.google.com/bigquery/docs/arrays) in BigQuery, e.g. for [filtering](https://cloud.google.com/bigquery/docs/arrays#filtering_arrays) or [zipping](https://cloud.google.com/bigquery/docs/arrays#zipping_arrays) arrays. In ClickHouse these operations are just a simple function call of the higher order functions [`arrayFilter`](/sql-reference/functions/array-functions#arrayfilterfunc-arr1-), and [`arrayZip`](/sql-reference/functions/array-functions#arrayzip), respectively.
