Alibaba Cloud Elasticsearch provides a scenario-based configuration feature. This
feature allows you to use the scenario-based templates that are provided by Alibaba
Cloud Elasticsearch to modify the configurations of your Alibaba Cloud Elasticsearch
cluster. These templates help you achieve optimal cluster and index configurations
and avoid cluster exceptions and performance issues that are caused by incorrect configurations.
Before you use the templates, you must specify a scenario. General, data analysis,
database acceleration, and search scenarios are supported. This topic describes how
to use a scenario-based template to modify the configurations of a cluster.
Background information
Before you use a scenario-based template to modify the configurations of a cluster,
take note of the following items:
- Different versions and types of clusters support different templates. The templates
available in the console take precedence.
- Standard Edition clusters support general, data analysis, database acceleration, and
search scenarios. Advanced Edition clusters support only logging scenarios.
- The default index template is named aliyun_default_index_template. This template has
a low order value and does not affect your custom index templates.
- The policy defined in the default index lifecycle template is named aliyun_default_ilm_policy.
This policy has been applied to the default index template aliyun_default_index_template.
- When you purchase a cluster, you can select a scenario on the buy page. The default
scenario for a Standard Edition cluster is General and that for an Advanced Edition
cluster is Logging. After a cluster is purchased, the system automatically applies
the configurations in related templates to the cluster.
Notice If Scenario is None, you can set it based on the following steps. If you set Scenario to a value other
than None, you must submit the related templates before they can be applied to the
cluster.
Procedure
- Log on to the Elasticsearch console.
- In the left-side navigation pane, click Elasticsearch Clusters.
- Navigate to the desired cluster.
- In the top navigation bar, select a resource group and a region.
- In the left-side navigation pane, click Elasticsearch Clusters. On the Elasticsearch Clusters page, find the desired cluster and click its ID.
- In the left-side navigation pane of the page that appears, click Cluster Configuration.
- In the Scenario-based Configuration section, click Modify on the right side of Scenario.
- In the Select Scenario dialog box, select a scenario from the Scenario drop-down list and click OK.
Notice Modifications in the Scenario-based Configuration section immediately take effect.
You do not need to restart your cluster.
- Use scenario-based templates to modify the configurations of your cluster.

- Dynamic Cluster Configuration: allows you to dynamically modify cluster configurations.
Dynamic Cluster Configuration functions the same as the
PUT /_cluster/settings
command. For more information, see Cluster update settings.
- Index Template Configuration: defines the template that is automatically used only
when an index is created. Index Template Configuration functions the same as the
PUT _template/aliyun_default_index_template
command. The modifications of the index template do not affect existing indexes.
For more information, see Index Templates.
- Index Lifecycle Configuration: supports clusters of V6.7.0 or later, regardless of
whether the clusters are Standard or Advanced Edition clusters. Index Lifecycle Configuration
functions the same as the
PUT _ilm/policy/aliyun_default_ilm_policy
command. For more information, see Setting up a new policy.
The following substeps demonstrate how to modify the configurations in an index template.
- Click Index Template Configuration.
- In the Index Template Configuration panel, click Apply.

The following features are provided:
- Apply: applies the configurations in the Template section to the Current Configuration
section. Then, you can modify the configurations.
- Compare: compares the configurations in the Current Configuration section with those in the
Template section. If no modifications are made, this feature is unavailable. During
the comparison, you cannot modify the configurations.
- Reset: restores the configurations in the Current Configuration section to the original
values.
- In the Current Configuration section, modify the configurations based on your business requirements.
- Click Compare.
- Click Cancel.
- Click Submit.
After you click Submit, the modifications immediately take effect on your cluster.
