Configuration XML for search integration
Suggest changes
PDFs
The search integration service is configured using a set of rules contained within <MetadataNotificationConfiguration> and </MetadataNotificationConfiguration> tags. Each rule specifies the objects that the rule applies to, and the destination where StorageGRID should send those objects' metadata.
Objects can be filtered on the prefix of the object name. For example, you could send metadata for objects with the prefix images to one destination, and metadata for objects with the prefix videos to another. Configurations that have overlapping prefixes aren't valid, and are rejected when they are submitted. For example, a configuration that includes one rule for objects with the prefix test and a second rule for objects with the prefix test2 is not allowed.
Destinations must be specified using the URN of a StorageGRID endpoint that has been created for the search integration service. These endpoints refer to an index and type defined on an Elasticsearch cluster.
<MetadataNotificationConfiguration>
<Rule>
<ID>Rule-1</ID>
<Status>rule-status</Status>
<Prefix>key-prefix</Prefix>
<Destination>
<Urn>arn:aws:es:region:account-ID:domain/mydomain/myindex/mytype</Urn>

The table describes the elements in the metadata notification configuration XML.
| Name | Description | Required |
|---|---|---|
MetadataNotificationConfiguration |
Container tag for rules used to specify the objects and destination for metadata notifications. Contains one or more Rule elements. |
Yes |
Rule |
Container tag for a rule that identifies the objects whose metadata should be added to a specified index. Rules with overlapping prefixes are rejected. Included in the MetadataNotificationConfiguration element. |
Yes |
ID |
Unique identifier for the rule. Included in the Rule element. |
No |
Status |
Status can be 'Enabled' or 'Disabled'. No action is taken for rules that are disabled. Included in the Rule element. |
Yes |
Prefix |
Objects that match the prefix are affected by the rule, and their metadata is sent to the specified destination. To match all objects, specify an empty prefix. Included in the Rule element. |
Yes |
Destination |
Container tag for the destination of a rule. Included in the Rule element. |
Yes |
Urn |
URN of the destination where object metadata is sent. Must be the URN of a StorageGRID endpoint with the following properties:
Endpoints are configured using the Tenant Manager or Tenant Management API. They take the following form:
The endpoint must be configured before the configuration XML is submitted, or configuration will fail with a 404 error. URN is included in the Destination element. |

Metadata notification configuration that applies to all objects
In this example, object metadata for all objects is sent to the same destination.
<MetadataNotificationConfiguration>
<Rule>
<ID>Rule-1</ID>
<Status>Enabled</Status>
<Prefix></Prefix>
<Destination>
<Urn>urn:myes:es:::sgws-notifications/test1/all</Urn>
</Destination>
</Rule>
</MetadataNotificationConfiguration>
Metadata notification configuration with two rules
In this example, object metadata for objects that match the prefix /images is sent to one destination, while object metadata for objects that match the prefix /videos is sent to a second destination.
<MetadataNotificationConfiguration>
<Rule>
<ID>Images-rule</ID>
<Status>Enabled</Status>
<Prefix>/images</Prefix>
<Destination>
<Urn>arn:aws:es:us-east-1:3333333:domain/es-domain/graphics/imagetype</Urn>
</Destination>
</Rule>
<Rule>
<ID>Videos-rule</ID>
<Status>Enabled</Status>
<Prefix>/videos</Prefix>
<Destination>
<Urn>arn:aws:es:us-west-1:22222222:domain/es-domain/graphics/videotype</Urn>
</Destination>
</Rule>
</MetadataNotificationConfiguration>
