How to get Timestamp from AddEntity response in aztables?

[prince776]

Hello,
I am using aztables package.

github.com/Azure/azure-sdk-for-go/sdk/data/aztables v1.1.0

As mentioned in the doc, i have created a service client like:

	newTableServiceClient, err := aztables.NewServiceClientWithSharedKey(
		"validEndpoint",
		creds,
		nil, // options
	)

Then I try to add an entity like:

	resp, err = c.newTableServiceClient.NewClient(entity.Table.Name).AddEntity(
		ctx,
		serializedEntity,
		nil, // options
	)

This return value has only the ETag however I also want other metadata fields, especially the timestamp.

This AddEntity method calls InsertEntity method of an internal interface (so I can't use it). Inside this method, all the extra fields I require are present at

	resp, err := client.insertEntityHandleResponse(httpResp)
	return resp, err

(validated manually)

But then this response is trimmed down to only have ETag before the AddEntity method returns (by converting to a minimal type)

I want to know what's the idiomatic/suggested way I can get this information?
The only way I am able to think is adding custom Pipeline policy that we pass to the TableServiceClient:

	// PerCallPolicies contains custom policies to inject into the pipeline.
	// Each policy is executed once per request.
	PerCallPolicies []Policy

	// PerRetryPolicies contains custom policies to inject into the pipeline.
	// Each policy is executed once per request, and for each retry of that request.
	PerRetryPolicies []Policy

but this would be a bit tedious imo, so wanted to consult here.

Thanks

By timestamp I assume you're referring to the Date field in the internal response type yes? I'm not sure why this and other fields weren't exported. I'll follow up on this.

[jhendrixMSFT]

Oh I think what you want is the Value field.

@jhendrixMSFT Thanks for the response
You're correct I need the Date field.
However please note that if we specify that we want full metadata and response preference of content
We get date in the Value field as well

So either

• just exposing the Date field or,
• allowing more flexibility on query options on the AddEntity and then exposing the Values field
  is required.

[jhendrixMSFT]

For whatever reason, we disable response metadata and don't provide an option to toggle it. I think it would be best to expose the Value and then add an option to toggle the behavior.

Thanks @jhendrixMSFT
Just want to mention that the issue applies to other methods of this client as well.
For example: GetEntity:

func (t *Client) GetEntity(ctx context.Context, partitionKey string, rowKey string, options *GetEntityOptions) (GetEntityResponse, error) {

Here while we do send back the Value in GetEntityResponse we do not allow increasing metadata level using options param as right now it is empty and just hardcodes to minimalMetadata.

The feature will be available in aztables@v1.2.0 scheduled to release next week on 3/5.

Unfortunately there was a delay in the release, it's available now.
