Another is that:
```
class PARQUET_EXPORT ArrowReaderProperties {
public:
explicit ArrowReaderProperties(bool use_threads = kArrowDefaultUseThreads)
: use_threads_(use_threads),
read_dict_indices_(),
batch_size_(kArrowDefaultBatchSize),
pre_buffer_(true),
cache_options_(::arrow::io::CacheOptions::LazyDefaults()),
coerce_int96_timestamp_unit_(::arrow::TimeUnit::NANO) {}
```
we have a cache_options, can you change this to
`::arrow::io::CacheOptions::Defaults()`. This could make s3 request runs
concurrently.
read a 700MB file using 10min is too slow. This could be well optimized
using different fetch options
