Elasticsearch bulk index api via rest endpoint

Question

Here is my request:

POST /_bulk
{ "index" : { "_index" : "test", "_type" : "type1", "_id" : "1" } }
{"firstname":"first_name1","lastname":"last_name1"},
{"firstname":"first_name2","lastname":"last_name2"},
{"firstname":"first_name3","lastname":"last_name3"}}

Here is the error:

{    "error": "IllegalArgumentException[Malformed action/metadata line [3], expected START_OBJECT or END_OBJECT but found

[VALUE_STRING]]", "status": 500 }

Basically, each document is {"firstname": ___, "lastname": ____} I don't want to wrap them into a parent field. What am I fundamentally missing?

this is also a helpful, related link: discuss.elastic.co/t/… — phirschybar

You're simply missing an action line for the second and third documents, try like this:

POST /_bulk
{ "index" : { "_index" : "test", "_type" : "type1", "_id" : "1" } }
{"firstname":"first_name1","lastname":"last_name1"}
{ "index" : { "_index" : "test", "_type" : "type1", "_id" : "2" } }
{"firstname":"first_name2","lastname":"last_name2"}
{ "index" : { "_index" : "test", "_type" : "type1", "_id" : "3" } }
{"firstname":"first_name3","lastname":"last_name3"}

The Don't Repeat Yourself section suggests a way to avoid repeating _index and _type value all the time. However, please note that, action must be still specified for each document.

Val Over a year ago

Of course, it's always better to specify the index and the type directly in the URL if possible. That was just to illustrate the _bulk action

Samyak Bhuta Over a year ago

yes. Earlier, I got a wrong impression when I read the document and thought that providing action at only the beginning of the file would serve the purpose well. I learnt that's not the case hard way.

Is there a way to upload a multiple json data in same index with auto id increment ? @samyak-bhuta

As Samyak says in his comment, "don't repeat yourself". This syntax is tidier.

post /test/_type/_bulk
{ "index": {}}
{"firstname":"first_name1","lastname":"last_name1"}
{ "index": { }}
{ "name": "Test2", "data": "This is my test data2" }
