### Question
I set the split-size smaller than files on s3. Each snapshot has 16
added-files.
When reading data, only 16 splits can be obtained at a time, which is
consistent with the number of files on S3.
Can files on s3 be splited?
The query sql is as follows:
select * from
realtime_catalog.trancare_realtime_dws.dws_stability_app_crash_10min
/*+ OPTIONS('streaming'='true', 'monitor-interval'='120s',
'start-snapshot-id'='8326101375840043894',
'max-planning-snapshot-count'='1','split-size'='52428','split-file-open-cost'='5242')*/
The snapshot in dws_stability_app_crash_10min is as follows:
"sequence-number" : 13553,
"snapshot-id" : 2706808882911224212,
"parent-snapshot-id" : 4090495094516144724,
