HAPI Bulk API operations issues on local HAPI instance

[akakl...@gmail.com]

Hello!

I've found, that $export operation doesn't work on HAPI local instance.

Steps:
 - download and run HAPI https://github.com/hapifhir/hapi-fhir-jpaserver-starter/tree/rel_4_1_0

 - upload data  https://drive.google.com/open?id=19O32q_ZmavcIkxANt8YkzSd3_lHoqyhC  (this is bundle for jmeter. Tu upload via POSTMAN  just  replace ${PATIENT_ID}  with any id , e.g.123 )

 - run GET http://localhost:13005/hapi-fhir-jpaserver/fhir/$export?_type=Observation&_typeFilter=Observation?status=registered

- run link from header's response GET http://localhost:13005/hapi-fhir-jpaserver/fhir/$export-poll-status?_jobId=116845da-45d4-4594-9161-7c1e81dd3f48

- run link

  "output": [

    {

      "type": "Observation",

      "url": "http://localhost:13005/hapi-fhir-jpaserver/fhir/Binary/9648"

    },

    {

      "type": "Observation",

      "url": "http://localhost:13005/hapi-fhir-jpaserver/fhir/Binary/9649"

    }, ...ETC

  

}

- observe results https://drive.google.com/open?id=1BywdWsw5EdnZpEAdmTf-39wrAVcwmpGr Result : No data filtered by status = registered

Tell please, if something has to be configured additionally for proper filters work. Or it's a bug?

Thank you !

I don't know for sure that this is the issue, but that second "?" in your URL isn't valid in a URL. You'll need to percent-encode that.

Cheers,

James

Hi, James!
I've tried as you proposed , but result is the same :(

http://localhost:13005/hapi-fhir-jpaserver/fhir/$export?_type=Observation&_typeFilter=Observation%3Fstatus%3Dregistered

Hi, James !
I've found, also, that   $export operation doesn’t export just uploaded data

SteSteps to reproduce

o   Upload data to server

o   Run $export

o   Get link from header

o   Observe data (e.g. 2000 entries of “DocumentReference”)

o   Upload new datd to server (e.g. + 500 entries of “DocumentReference”)

o   Run $export

o   Get link from header  ( job ID remains the same)

o   Observe data 

o   Result 2000 entries od Document reference )

Don't you kow , probably it's needed to configure server to refresh export jobs on every$export request ?

James,

It seems like there is a bug in $export method. What I can see is that Anton has tried to

a) load  2000 resources

b) do $export (got back 2000 resources)

c) load additional 500 resources  

d) do $export again

and it seems like he gets back X resources instead of 2000+500 resources. 

So $export works correctly only for the first time. It sounds like there some cash not cleared up. 

Is there any workaround (including some DB table clean up) so HAPI FHIR Server would do the operation from scratch and counted all 2500 resources?

Hello, 

When I used $export  - application always returns the same JobID. And therefore results of export are always the same

When I tried to invoke DELETE with http://localhost:8889/hapi-fhir-jpaserver/fhir/$export-poll-status?_jobId=e005f5d7-7a2d-437a-87f2-7e792dda3ed7

it shows error that server can not do such an operation. It seems that it is not implemented. 

In this case how can I re-export data (delete previous export results)?

Thanks,

Andrew

The bulk export currently has a cache on export results that is (I believe) 1 hour, and we don't yet provide any mechanism for overriding it. Agree that would be a useful enhancement.

Hello James, 

Thank you for your answer.

One more question - could you please clarify what happen after one export operation is complete? When I invoke this operation second time(with no changes in FHIR server - no any new resources), I found that there is no resources exported 

The only JSON I have got

{

  "transactionTime" : "2019-11-20T12:19:29.776+00:00",

  "request" : "/$export?_outputFormat=application%2Ffhir%2Bndjson"

}

Is it correct behavior? 

Thanks,

Andrew
