Elasticsearch: Error : curl(56) Recv failure: Connection reset by peer

Please use discuss.elastic.co

Try to reduce your bulk size. I think I don't insert more than 10k docs per bulk (small docs). So, some mb at most per bulk.

But elasticsearch is made for handling big size data some GBs of data , even wiki and github are also using it .

I think reducing the input size is not a good solution , but I somehow managed to insert the data using python ..

Even then if someone can suggest me best possible solution then kindly comment

Yes. I can confirm that elasticsearch can handle billions of documents, trillions of documents.
It does not mean that you can pass all those docs within one single bulk request.

Have a look BTW at http.max_content_length. By default it's limited to 100mb (on purpose).
