Various improvements to getValue(fieldIdx) in RowWithGetters mentioned [here]([https://github.com/apache/beam/pull/16947#discussion_r833602836):] * Minimize memory overhead of cache using either a index lookup (array) or a single hash map if number of fields exceeds the initial hashmap capacity * The cache should be checked before calling a getter to avoid any potentially unnecessary conversion in the getter itself. * [Nested rows](https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/values/RowWithGetters.java#L111) should be cached, otherwise the cache of such nested rows can't be leveraged. * Handling of collections / maps / iterables can be significantly improved by simply skipping the transform in all cases where `getValue` for members is the [identity transform](https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/values/RowWithGetters.java#L142).
