Writes the records from a FlowFile into to Elasticsearch, using the specified parameters such as the index to insert into and the type of the document, as well as the operation type (index, upsert, delete, etc.). Note: The Bulk API is used to send the records. This means that the entire contents of the incoming flow file are read into memory, and each record is transformed into a JSON document which is added to a single HTTP request body. For very large flow files (files with a large number of records, e.g.), this could cause memory usage issues.

In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, whether a property supports the Expression Language Guide, and whether a property is considered “sensitive”, meaning that its value will be encrypted. Before entering a value in a sensitive property, ensure that the nifi.propertiesfile has an entry for the property nifi.sensitive.props.key.


Default Value

Allowable Values


Elasticsearch URL

Elasticsearch URL which will be connected to, including scheme (http, e.g.), host, and port. The default port for the REST API is 60017.

Supports Expression Language: true

SSL Context Service

Controller Service API:




The SSL Context Service used to provide client certificate information for TLS/SSL connections. This service only applies if the Elasticsearch endpoint(s) have been secured with TLS/SSL.
Username Username to access the Elasticsearch cluster

Supports Expression Language: true

Password Password to access the Elasticsearch cluster

Sensitive Property: true

Supports Expression Language: true

Connection Timeout

5 secs Max wait time for the connection to the Elasticsearch REST API.

Supports Expression Language: true

Response Timeout

15 secs Max wait time for a response from the Elasticsearch REST API.

Supports Expression Language: true

Record Reader

Controller Service API:









Specifies the Controller Service to use for parsing incoming data and determining the data's schema.
Identifier Record Path A RecordPath pointing to a field in the record(s) that contains the identifier for the document. If the Index Operation is "index", this property may be left empty or evaluate to an empty value, in which case the document's identifier will be auto-generated by Elasticsearch. For all other Index Operations, the field's value must be non-empty.

Supports Expression Language: true


The name of the index to insert into

Supports Expression Language: true


The type of this document (used by Elasticsearch for indexing and searching)

Supports Expression Language: true

Index Operation

index The type of the operation used to index (index, update, upsert, delete)

Supports Expression Language: true




retry A FlowFile is routed to this relationship if the database cannot be updated but attempting the operation again may succeed
