Unable to fetch just the metadata
Closed this issue · 4 comments
It seems there's no way to fetch just the metadata in v2 of the sdk.
In v1, S3Object has a metadata method.
This seems to be gone in v2. The only thing I can see that's similar is to use S3::Object's get method which unfortunately retrieves the whole object wasting bandwidth.
Update:
Closed as this repo is moved. Opened an issue here aws/aws-sdk-ruby#722
Use the #head_object method.
Sorry, to be more clear. Use the head object method of the client class or the #metadata method of S3::Object.
That works well. Thanks.
Might I propose a head_object method for the S3::ObjectSummary class in the future?
@chenkirk You can also cast a S3::ObjectSummary
to a S3::Object
using the #object
method:
s3.bucket('aws-sdk').objects.each do |obj_summary|
obj = obj_summary.object
puts obj.metdata.inspect # WARNING : makes one HEAD Object request for each obj in the bucket
end
Adding a #head
method directly to the ObjectSummary class isn't a bad idea.
