Allow configuring S3 StorageClass

[amitsetty]

Currently I can’t configure grafana tempo to use the SATA S3 StorageClass

Would want to add this as a configurable feature

Can you give more information about how you would expect this feature to be enabled in Tempo? Is this something that can be configured on the bucket?

Hey @joe-elliott ,
I think what @amitsetty is meaning is to change the default storage class.
The default storage class is STANDARD, and it is the most expensive class in Amazon.
It would be great to have a configurable option to change that to STANDARD_IA or even GLACIER.

Ok, did some research. I figured this was something that was configurable on the bucket, but it seems like this is set at upload time?

I am open to a PR to set this. I believe it would need to be set in two places:

tempo/tempodb/backend/s3/s3.go

Line 110 in e177ad0

putObjectOptions := minio.PutObjectOptions{

tempo/tempodb/backend/s3/s3.go

Line 141 in e177ad0

options := minio.PutObjectOptions{

Also, i'm thinking we need a method to generate PutObjectOptions given the current config.

I would however warn against using storage classes such as Glacier as Tempo objects are accessed constantly.
