Are Smartstore buckets uploaded to S3 immutable?

Are Smartstore buckets uploaded to S3 immutable?  We've been using Smartstore for almost a year and I have never seen an update to a bucket after its original upload to S3.  Can anyone confirm this?

The whole S3 SmartStore bucket is not immutable. At least in my instance anyway.
The actual index data, tsidx files, and other metadata files subtending the 'db' folder are immutable.

However, data model acceleration files located under the 'dma' folder do get updated/deleted as a normal part of Splunk operation.

Do we have something misconfigured here? Or, is what am what I am saying normal?

That's normal and is just like on-prem.

Just like warm and cold on-prem buckets, S2 buckets never change.

As I am learning with Write-Once-Read-Many (WORM), there are situations where the buckets/tsidx files are re-uploaded when the indexers have hiccups during an upload.
