UpdateByQueryElasticsearch 2.3.0¶

org.apache.nifi | nifi-elasticsearch-restapi-nar

DESCRIPTION¶

Update documents in an Elasticsearch index using a query. The query can be loaded from a flowfile body or from the Query parameter. The loaded Query can contain any JSON accepted by Elasticsearch’s _update_by_query API, for example a “query” object to identify what documents are to be updated, plus a “script” to define the updates to perform.

PROPERTIES¶

Property	Description
Max JSON Field String Length	The maximum allowed length of a string value when parsing a JSON document or attribute.
el-query-attribute	If set, the executed query will be set on each result flowfile in the specified attribute.
el-rest-client-service	An Elasticsearch client service to use for running queries.
el-rest-fetch-index	The name of the index to use.
el-rest-query	A query in JSON syntax, not Lucene syntax. Ex: {“query”:{“match”:{“somefield”:”somevalue”}}}. If this parameter is not set, the query will be read from the flowfile content. If the query (property and flowfile content) is empty, a default empty JSON Object will be used, which will result in a “match_all” query in Elasticsearch.
el-rest-query-clause	A “query” clause in JSON syntax, not Lucene syntax. Ex: {“match”:{“somefield”:”somevalue”}}. If the query is empty, a default JSON Object will be used, which will result in a “match_all” query in Elasticsearch.
el-rest-query-definition-style	How the JSON Query will be defined for use by the processor.
el-rest-script	A “script” to execute during the operation, in JSON syntax. Ex: {“source”: “ctx._source.count++”, “lang”: “painless”}
el-rest-type	The type of this document (used by Elasticsearch for indexing and searching).

RELATIONSHIPS¶

NAME	DESCRIPTION
failure	If the “by query” operation fails, and a flowfile was read, it will be sent to this relationship.
retry	All flowfiles that fail due to server/cluster availability go to this relationship.
success	If the “by query” operation succeeds, and a flowfile was read, it will be sent to this relationship.

WRITES ATTRIBUTES¶

NAME	DESCRIPTION
elasticsearch.update.took	The amount of time that it took to complete the update operation in ms.
