Amazon S3 query using regular expression

Question

I have the following folder structure in S3.

myBucket/20190313/20190313_100000/_SUCCESS

I need to check whether there is _SUCCESS File present

Query I am currently using:

date = 20190313
bucket = s3Resource.Bucket(myBucket)
objs = list(bucket.objects.filter(Prefix=date+'/'))

I do not know what will be inside of the date folder. But is in yyyymmdd_hhmmss format.

Is there a way to query for that specific "_SUCCESS" file, if only "myBucket/20190313/" is known?

Answer 1

The API docs says that you cant use a regex

Limits the response to keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys. (You can think of using prefix to make groups in the same way you would use a folder in a file system.)
