How to control listblobs maxresults argument?

[mortenjoenby]

We are running AKS 1.31 using Blobfuse CSI driver.
We have been looking into diagnostics due to increased cost when using Azure Vault Backups and also when disabling cache.
Using Log Analytics Workspace we see a lot of ListBlobs calls (not unusual of course), but notice that all calls have "maxresults=2" set:

https://xxxxxxxxx.blob.core.windows.net:443/preprod-sharedstorage?comp=list&delimiter=%2F&include=metadata&maxresults=2&prefix=workarea%2Fhealthcheck%2Fproblems%2FLargeCommit.xml&restype=container

We would like to control the maxresults, but we can't figure out how - and if possible at all.
Why is it set to 2?
Any concerns if changing it?

Seems on 2.5.0 it's set to 2 and does have a configurable setting:

Hi @mortenjoenby, "maxresults=2" is used by Blobfuse when listBlob api is used to retrieve properties of a file. As you can see, in the sample request that you have posted also has file/directory name "prefix=". These are special calls and not trying to list all objects in a directory.
When you execute a 'ls' command, you will observe "maxResults=5000" in those calls, which is max that Azure storage backend supports. Config that you have pointed is not a general-purpose config and shall not be used by customers. It's meant only to simulate certain scenarios during our testing.
