I am trying to figure out the cost of operations for azure storage accounts and the API calls confuse me.

For general purpose v1, I found this:

*The following API calls are considered write operations: AbortCopyBlob, AppendBlock, BreakBlobLease, BreakContainerLease, ChangeBlobLease, ChangeContainerLease, CopyBlob, CreateContainer, IncrementalCopyBlob, PutBlob, PutBlock, PutBlockList, PutGeoMessage, PutGeoRepairMessageMeasurementEvent, PutGeoVerificationMessageMeasurementEvent, SetBlobMetadata, SetBlobProperties, SetBlobServiceProperties, SetContainerACL, SetContainerMetadata, SnapshotBlob, and UndeleteBlob.

**The following API calls are considered read operations: AcquireBlobLease, AcquireContainerLease, BlobPreflightRequest, GeoBootstrap, GetBlob, GetBlobLeaseInfo, GetBlobMetadata, GetBlobProperties, GetBlobServiceProperties, GetBlobServiceStats, GetBlockList, GetContainerACL, GetContainerMetadata, GetContainerProperties, GetCopyInformation, GetEncryptionKey, ReleaseBlobLease. ReleaseContainerLease, RenewBlobLease, and RenewContainerLease.

But the information is limited for general purpose v2 storage accounts:

1 The following API calls are considered write operations: PutBlob, PutBlock, PutBlockList, AppendBlock, SnapshotBlob, CopyBlob, and SetBlobTier (when it moves a Blob from Hot to Cool, Cool to Archive, or Hot to Archive. Learn more).

2 The following API calls are considered list and create container operations: ListBlobs, ListContainers, FindBlobsByTags, and CreateContainer.

3 The following API calls are considered read operations: GetBlob and SetBlobTier (when it moves a Blob from Archive to Cool, Cool to Hot, or Archive to Hot

Does this mean that GetBlobProperties falls under "All other Operations" for v2 unlike v1 where it is classified as a read operation?

This makes a huge difference in the total costs we are likely to incur since the cost of All other operations is half that of read operations.
