Class GcsFilesetSpec (1.2.0)

Describes a Cloud Storage fileset entry.

Required. Patterns to identify a set of files in Google Cloud Storage. See Cloud Storage documentation for more information. Note that bucket wildcards are currently not supported.

Examples of valid file_patterns:

• gs://bucket_name/dir/*: matches all files within bucket_name/dir directory.
• gs://bucket_name/dir/**: matches all files in bucket_name/dir spanning all subdirectories.
• gs://bucket_name/file*: matches files prefixed by file in bucket_name
• gs://bucket_name/??.txt: matches files with two characters followed by .txt in bucket_name
• gs://bucket_name/[aeiou].txt: matches files that contain a single vowel character followed by .txt in bucket_name
• gs://bucket_name/[a-m].txt: matches files that contain a, b, ... or m followed by .txt in bucket_name
• gs://bucket_name/a/*/b: matches all files in bucket_name that match a/*/b pattern, such as a/c/b, a/d/b
• gs://another_bucket/a.txt: matches gs://another_bucket/a.txt

You can combine wildcards to provide more powerful matches, for example:

• gs://bucket_name/[a-m]??.j*g

Output only. Sample files contained in this fileset, not all files contained in this fileset are represented here.
