WARNING: Version 1.7 of Elasticsearch has passed its EOL date.

Bulk UDP API
editBulk UDP API
editBulk 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:
-
bulk.udp.bulk_actions -
The number of actions to flush a bulk after,
defaults to
1000. -
bulk.udp.bulk_size -
The size of the current bulk request to flush
the request once exceeded, defaults to
5mb. -
bulk.udp.flush_interval -
An interval after which the current
request is flushed, regardless of the above limits. Defaults to
5s. -
bulk.udp.concurrent_requests -
The number on max in flight bulk
requests allowed. Defaults to
4.
The allowed network settings are:
-
bulk.udp.host -
The host to bind to, defaults to
network.hostwhich defaults to any. -
bulk.udp.port -
The port to use, defaults to
9700-9800. -
bulk.udp.receive_buffer_size -
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
