An Elasticsearch profile is used to read and write data in an Elasticsearch Service in AWS and can be accessed by batch workflows using Aggregation agents. Elasticsearch is supported to provide a scalable distributed storage option. It is a search and analytics engine that provides high scalability on a cloud infrastructure with cluster scaling options and replication across several domains, and the capacity to query large amounts of data.

For further information on the use of Elasticsearch, see https://www.elastic.co/guide/en/elasticsearch/reference/6.0/index.html.

Configuration

To create a new Elasticsearch profile, click the New Configuration button in the upper left part of the the Image Added Desktop window, and then select Elasticsearch  Profile  from the menu.

The contents of the menus in the menu bar may change depending on which configuration type that has been opened in the currently displayed tab. The Elasticsearch profile uses the standard menu items and buttons that are visible for all configurations, and these are described in Menus and Buttons.

The Edit menu is specific for the Elasticsearch profile configurations.

ItemDescription

External References

Select this menu item to Enable External References in an agent profile field. This can be used to configure the use of the following fields, and the respective external reference keys available:

  • Index

Note
titleNote!

The Node Config must be entered in in the form of a comma separated list of <host:port> values, for example, 127.0.0.1:8990, 123.0.0.1:9000.

For further information, see Using External Reference in Agent Profile Fields and External Reference Profile.

The Elasticsearch profile configuration consists of two tabs: Connectivity and Advanced.

Connectivity Tab

The Connectivity tab is displayed by default. The following settings are available in the Elasticsearch profile:

SettingDescription
Index

Enter the index that you want to use. For further information on the use of an index in Elasticsearch, see https://www.elastic.co/guide/en/elasticsearch/reference/6.0/_basic_concepts.html.

Note
titleNote!

When you name your index, bear in mind that two indices are created in the background for a workflow, which are named <index name>_committed and <index name>_deleted. It is therefore important to avoid naming an index which would duplicate these index names. For example, if you name the index "customer_index", the indices "customer_index_committed" and "customer_index_deleted" are automatically created. These two additional indices are removed after the workflow has been run.


Host

Enter the host name or IP address of the host on which the Elasticsearch service is running.

Port

Enter the port of the Elasticsearch service.

Test Connection

Click to test the connection to the service, using the configured values.

Advanced Tab

The Advanced tab contains additional properties that you can use for performance tuning for the Elasticsearch service.
