Hi! I’m having an hard time dealing with this GMS api. For example: I have some datasets created. And I want to add (in this case I’m cheking create) an upstreamLineage to it. So I created the following request (I want to add to dataset bill-invoice the upstream dataset entitlement-server):

curl --location --request CREATE '<http://localhost:8080/datasets/($params:(),name:bill-invoice,origin:PROD,platform:billing)/upstreamLineage>' \
--header 'X-RestLi-Protocol-Version: 2.0.0' \
--header 'Content-Type: application/json' \
--data-raw '{
    "upstreams": [
        {
            "auditStamp": {
                "actor": "urn:li:corpuser:ordering.product-offering",
                "impersonator": "urn:li:corpuser:ordering.product-offering",
                "time": 7
            },
            "dataset": "urn:li:dataset:(urn:li:dataPlatform:entitlement-server,es-go,DEV)",
            "type": "TRANSFORMED"
        }
    ]
}'

But gives me an error:

java.lang.IllegalArgumentException: No enum constant com.linkedin.restli.common.HttpMethod.CREATE

Using POST will result on an exception from server. I’m basing on the following: http://localhost:8080/restli/docs/rest/datasets.upstreamLineage

Hello! To update your dataset partially (i.e. just add for example a new upstream lineage to the list of upstreams without rewriting all of existing ones), you should use deltaUpdate action which can be used something like this:

curl -s -H 'X-RestLi-Protocol-Version:2.0.0' -XPOST \

'<http://localhost:8080/datasets/($params:(),name:bill-invoice,origin:PROD,platform:billing)/upstreamLineage?action=deltaUpdate>' -d'{
"delta": { "upstreamsToAdd": [...] }
}'

what is the exception when you try POST?

@aloof-window-16847 Hi Thank you for the answer, I also tried deltaUpdate action without any success:

curl --location --request POST '<http://localhost:8080/datasets/($params:(),name:bill-invoice,origin:PROD,platform:billing)/upstreamLineage?action=deltaUpdate>' \
--header 'X-RestLi-Protocol-Version: 2.0.0' \
--header 'Content-Type: application/json' \
--data-raw '{
    "delta": {
        "upstreamsToUpdate": [
            {
                "auditStamp": {
                    "actor": "urn:li:corpuser:ordering.product-offering",
                    "impersonator": "urn:li:corpuser:ordering.product-offering",
                    "time": 7
                },
                "dataset": "urn:li:dataset:(urn:li:dataPlatform:entitlement-server,es-go,DEV)",
                "type": "TRANSFORMED"
            }
        ]
    }
}'

It throws an invalid URN:

@damp-telephone-61279 The problem lies in the

platform

param, the platforms itself is an urn based structure, in your case, I guess it is sth called

urn:li:dataPlatform:billing

, could you please give it another try?

According to the documentation here: http://localhost:8080/restli/docs/rest/datasets.upstreamLineage the format should be something like this:

curl -v -X POST /datasets/($params:(),name:Doe,origin:DEV,platform:bar)/upstreamLineage?action=deltaUpdate -d @request_body           

request_body file:
{
  "delta" : {
    "upstreamsToUpdate" : [ ]
  }
}

With that it throws another error:

exceptionClass":"com.linkedin.restli.server.RestLiServiceException","stackTrace":"com.linkedin.restli.server.RestLiServiceException [HTTP Status:400]: Complex key query parameters parsing error: 'expected ')' but found ':' (column 54)'\n\tat com.linkedin.restli.server.RestLiServiceException.fromThrowable(RestLiServiceException.java:315)\n\tat com.linkedin.restli.server.BaseRestLiServer.buildPreRoutingError(BaseRestLiServer.java:158)\n\tat com.linkedin.restli.server.RestRestLiServer.buildPreRoutingRestException(RestRestLiServer.
....

Sorry for the confusions, we will help improve the documentation along the way. @ambitious-battery-33996. For this particular query, please try as Mar's suggested in a different thread:

curl --location --request GET '<http://localhost:8080/datasets/($params:(),name:billing,origin:PROD,platform:platform:urn%3Ali%3AdataPlatform%3Abilling)>'

Basically, in this case, platform is an urn, and also you need encoding around it.

@enough-house-33388 @cool-river-24902 Thank you for your support. So using it encoded actually worked for upstreamLineage deltaUpdate. Great success!!! Yeah! Url:

<http://localhost:8080/datasets/($params:(),name:bill-invoice,origin:PROD,platform:urn%3Ali%3AdataPlatform%3Abilling)/upstreamLineage?action=deltaUpdate>

However I still can’t make a simple get to this!

curl --location --request GET '<http://localhost:8080/datasets/($params:(),name:bill-invoice,origin:PROD,platform:urn%3Ali%3AdataPlatform%3Abilling)>'

Try adding

-H 'X-RestLi-Protocol-Version:2.0.0'

to your curl command.

Yep, that was the thing missing!!!
