Bulk UDP APIedit

Bulk UDP has been deprecated and will be removed in Elasticsearch 2.0. You should use the standard bulk API instead.

A Bulk UDP service is a service listening over UDP for bulk format requests. The idea is to provide a low latency UDP service that allows to easily index data that is not of critical nature.

The Bulk UDP service is disabled by default, but can be enabled by setting bulk.udp.enabled to true.

The bulk UDP service performs internal bulk aggregation of the data and then flushes it based on several parameters:

The number of actions to flush a bulk after, defaults to 1000.
The size of the current bulk request to flush the request once exceeded, defaults to 5mb.
An interval after which the current request is flushed, regardless of the above limits. Defaults to 5s.
The number on max in flight bulk requests allowed. Defaults to 4.

The allowed network settings are:

The host to bind to, defaults to network.host which defaults to any.
The port to use, defaults to 9700-9800.
The receive buffer size, defaults to 10mb.

Here is an example of how it can be used:

> cat bulk.txt
{ "index" : { "_index" : "test", "_type" : "type1" } }
{ "field1" : "value1" }
{ "index" : { "_index" : "test", "_type" : "type1" } }
{ "field1" : "value1" }
> cat bulk.txt | nc -w 0 -u localhost 9700
