Hi Otis, Elasticsearch makes use of asynchronous HTTP in order to scale well with large numbers of connections. I cannot say for sure what's the reason for putting this caveat into the Elasticsearch docs, but chunking can show weird interactions with clients in an asynchronous scenario. This could result in interleaved streams of data returned, which creates extra complexity on the consumer side. While chunking clearly has benefits for streaming data over HTTP, I don't see much of an advantage with Elasticsearch where the size of responses won't be extremely large or unbounded (due to window sizes/paging in result sets). Keep-alive seems to be sufficient.
Let's see if anybody else has a better explanation... or better guess :-) Best regards, --Jürgen On 16.11.2014 21:13, Otis Gospodnetic wrote: > Hi, > > http://www.elasticsearch.org/guide/en/elasticsearch/reference/1.4/modules-http.html > recommends NOT to use HTTP Chunking and to use Keep-Alive connections. > Yet, the HTTP chunking link there points > to http://en.wikipedia.org/wiki/Chunked_transfer_encoding , which > implies HTTP Chunking is good because it makes persistent connections > possible. > > Can anyone explain this apparent contradiction? > > Thanks, > Otis > -- > Monitoring * Alerting * Anomaly Detection * Centralized Log Management > Solr & Elasticsearch Support * http://sematext.com/ > > -- > You received this message because you are subscribed to the Google > Groups "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send > an email to [email protected] > <mailto:[email protected]>. > To view this discussion on the web visit > https://groups.google.com/d/msgid/elasticsearch/1d6408e5-4bca-4239-82fd-3c3df2388efb%40googlegroups.com > <https://groups.google.com/d/msgid/elasticsearch/1d6408e5-4bca-4239-82fd-3c3df2388efb%40googlegroups.com?utm_medium=email&utm_source=footer>. > For more options, visit https://groups.google.com/d/optout. -- Mit freundlichen Grüßen/Kind regards/Cordialement vôtre/Atentamente/С уважением *i.A.
