S3 output - Support for Glacier storage classes

[StefanTheWiz]

Is there a reason for excluding GLACIER (S3 Glacier Flexible Retrieval), GLACIER_IR (S3 Glacier Instant Retrieval), and DEEP_ARCHIVE (S3 Glacier Deep Archive) from the list of supported storage classes?

logstash-integration-aws/lib/logstash/outputs/s3.rb

Line 145 in fcd1f2a

config :storage_class, :validate => ["STANDARD", "REDUCED_REDUNDANCY", "STANDARD_IA", "ONEZONE_IA"], :default => "STANDARD"

Based on the AWS docs it seems that these classes do support multipart upload API.

Yes, I could use S3 lifecycle rules to transition the files to a different storage class. However, even if I set the rule to run on day 0 it takes 3 days to take effect (this is particularly not helpful when implementing/testing pipelines)
