[[ingest-enriching-data]]
|
|
== Enrich your data
|
|
|
|
You can use the <<enrich-processor,enrich processor>>
|
|
to append data from existing indices
|
|
to incoming documents during ingest.
|
|
|
|
For example, you can use the enrich processor to:
|
|
|
|
* Identify web services or vendors based on known IP addresses
|
|
* Add product information to retail orders based on product IDs
|
|
* Supplement contact information based on an email address
|
|
|
|
|

[[enrich-setup]]
|
|
=== Set up an enrich processor
|
|
|
|
To set up an enrich processor and learn how it works,
|
|
follow these steps:
|
|
|
|
. Check the <<enrich-prereqs, prerequisites>>.
|
|
. <<create-enrich-source-index>>.
|
|
. <<create-enrich-policy>>.
|
|
. <<execute-enrich-policy>>.
|
|
. <<add-enrich-processor>>.
|
|
. <<ingest-enrich-docs>>.
|
|
|
|
Once you have an enrich processor set up,
|
|
you can <<update-enrich-data,update your enrich data>>
|
|
and <<update-enrich-policies, update your enrich policies>>
|
|
using the <<enrich-apis,enrich>> APIs.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
The enrich processor performs several operations
|
|
and may impact the speed of your <<pipeline,ingest pipeline>>.
|
|
|
|
We strongly recommend testing and benchmarking your enrich processors
|
|
before deploying them in production.
|
|
|
|
We do not recommend using the enrich processor to append real-time data.
|
|
The enrich processor works best with reference data
|
|
that doesn't change frequently.

|
[[create-enrich-source-index]]
|
|
==== Create a source index
|
|
|
|
To begin,
|
|
create one or more source indices.
|
|
|
|
A *source index* contains data you want to append to incoming documents.
|
|
You can index and manage documents in a source index
|
|
like a regular index.
|
|
|
|
The following <<docs-index_,index>> API request creates the `users` source index
|
|
containing user data.
|
|
This request also indexes a new document to the `users` source index.
|
|
|
|
[source,console]
|
|
----
|
|
PUT /users/_doc/1?refresh
|
|
{
|
|
"email": "mardy.brown@asciidocsmith.com",
|
|
"first_name": "Mardy",
|
|
"last_name": "Brown",
|
|
"city": "New Orleans",
|
|
"county": "Orleans",
|
|
"state": "LA",
|
|
"zip": 70116,
|
|
"web": "mardy.asciidocsmith.com"
|
|
}
|
|
----
|
|
|
|
You also can set up {beats-ref}/getting-started.html[{beats}],
|
|
such as a {filebeat-ref}/filebeat-getting-started.html[{filebeat}],
|
|
to automatically send and index documents
|
|
to your source indices.
|
|
See {beats-ref}/getting-started.html[Getting started with {beats}].
|
|
|
|
|
|

|
[[create-enrich-policy]]
|
|
==== Create an enrich policy
|
|
|
|
Use the <<put-enrich-policy-api, put enrich policy>> API
|
|
to create an enrich policy.
|
|
|
|
include::{docdir}/ingest/apis/enrich/put-enrich-policy.asciidoc[tag=enrich-policy-def]
|
|
|
|
[source,console]
|
|
----
|
|
PUT /_enrich/policy/users-policy
|
|
{
|
|
"match": {
|
|
"indices": "users",
|
|
"match_field": "email",
|
|
"enrich_fields": ["first_name", "last_name", "city", "zip", "state"]
|
|
}
|
|
}
|
|
----
|
|
// TEST[continued]
|
|
|
|
|
|
[float]
|
|
[[execute-enrich-policy]]
|
|
==== Execute an enrich policy
|
|
|
|
Use the <<execute-enrich-policy-api, execute enrich policy>> API
|
|
to create an enrich index for the policy.
|
|
|
|
include::apis/enrich/execute-enrich-policy.asciidoc[tag=execute-enrich-policy-def]
|
|
|
|
The following request executes the `users-policy` enrich policy.
|
|
Because this API request performs several operations,
|
|
it may take a while to return a response.
|
|
|
|
[source,console]
|
|
----
|
|
POST /_enrich/policy/users-policy/_execute
|
|
----
|
|
// TEST[continued]

|
|
|
|

[float]
|
|
[[add-enrich-processor]]
|
|
==== Add the enrich processor to an ingest pipeline
|
|
|
|
Use the <<put-pipeline-api,put pipeline>> API
|
|
to create an ingest pipeline.
|
|
Include an <<enrich-processor,enrich processor>>
|
|
that uses your enrich policy.
|
|
|
|
When defining an enrich processor,
|
|
you must include the following:
|
|
|
|
* The *field* used to match incoming documents
|
|
to documents in the enrich index.
|
|
+
|
|
This field should be included in incoming documents.
|
|
To match, this field must contain the exact
|
|
value of the match field of a document in the enrich index.
|
|
|
|
* The *target field* added to incoming documents.
|
|
This field contains all appended enrich data.
|
|
|
|
The following request adds a new pipeline, `user_lookup`.
|
|
This pipeline includes an enrich processor
|
|
that uses the `users-policy` enrich policy.
|
|
|
|
[source,console]
|
|
----
|
|
PUT /_ingest/pipeline/user_lookup
|
|
{
|
|
"description" : "Enriching user details to messages",
|
|
"processors" : [
|
|
{
|
|
"enrich" : {
|
|
"policy_name": "users-policy",
|
|
"field" : "email",
|
|
"target_field": "user"
|
|
}
|
|
}
|
|
]
|
|
}
|
|
----
|
|
// TEST[continued]
|
|
|
|
You also can add other <<ingest-processors,processors>>
|
|
to your ingest pipeline.
|
|
You can use these processors to change or drop incoming documents
|
|
based on your criteria.
|
|
|
|
See <<ingest-processors>> for a list of built-in processors.
|
|
|
|

|
|
[[ingest-enrich-docs]]
|
|
==== Ingest and enrich documents
|
|
|
|
Index incoming documents using your ingest pipeline.
|
|
|
|
Because the enrich policy type is `match`,
|
|
the enrich processor matches incoming documents
|
|
to documents in the enrich index
|
|
based on match field values.
|
|
The processor then appends the enrich field data
|
|
from any matching document in the enrich index
|
|
to target field of the incoming document.
|
|
|
|
The enrich processor appends all data to the target field as an array.
|
|
If the incoming document matches more than one document in the enrich index,
|
|
the processor appends data from those documents to the array.
|
|
|
|
If the incoming document matches no documents in the enrich index,
|
|
the processor appends no data.
|
|
|
|
The following <<docs-index_,index>> API request uses the ingest pipeline
|
|
to index a document
|
|
containing the `email` field,
|
|
the `match_field` specified in the `users-policy` enrich policy.
|
|
|
|
[source,console]
|
|
----
|
|
PUT /my_index/_doc/my_id?pipeline=user_lookup
|
|
{
|
|
"email": "mardy.brown@asciidocsmith.com"
|
|
}
|
|
----
|
|
// TEST[continued]
|
|
|
|
To verify the enrich processor matched
|
|
and appended the appropriate field data,
|
|
use the <<docs-get,get>> API to view the indexed document.
|
|
|
|
[source,console]
|
|
----
|
|
GET /my_index/_doc/my_id
