helpers.bulk(es,doc) 

i tried both but no result,i am getting this error

elasticsearch.exceptions.RequestError: TransportError(400, u'illegal_argument_exception', u'Malformed action/metadata line [1], expected START_OBJECT or END_OBJECT but found [VALUE_STRING]')

please help me

I prefer using the bulk method present in helpers module for bulk indexing. Try the following:

from elasticsearch import helpers
res = helpers.bulk(es, jsonvalue, chunk_size=1000, request_timeout=200)

Your jsonvalue needs to follow a particular format. It needs to be a list of the 10K json documents with each document having the following fields:

doc = {
    '_index': 'your-index',
    '_type': 'your-type',
    '_id': 'your-id',
    'field_1': 'value_1',
    ...
}

So your final jsonvalue would look something like this:

jsonvalue = [
    {
    '_index': 'your-index',
    '_type': 'your-type',
    '_id': 'your-id',
    'field_1': 'value_1',
    ...
},
    {
    '_index': 'your-index',
    '_type': 'your-type',
    '_id': 'your-id',
    'field_1': 'value_2',
    ...
},
    {
    '_index': 'your-index',
    '_type': 'your-type',
    '_id': 'your-id',
    'field_1': 'value_3',
    ...
}
]
