Send smaller bulks. It does not make sense to send so big requests IMO.

my bulks are mails with attachments.

i use the attachment pipeline with ingest attachment processor plugin.

I have a volume of 3 million e-mail send to index.

thanks for reply 🙂

Send one attachment one by one or one email per one email...

At most, I'd not send to elasticsearch bulk requests with more than 50mb of data.

The other solution is to do the text extraction outside elasticsearch and send just the extracted text to elasticsearch.  
FSCrawler might help although I'm aware of limitations as well.
