The cluster configuration feature of Alibaba Cloud Elasticsearch allows you to customize the configurations of synonyms, garbage collectors, and YML files.

You can perform the following operations by using the cluster configuration feature of Elasticsearch:
  • Configure synonyms

    Upload a synonym dictionary file that is tailored to your business requirements. After the file is uploaded, the system automatically updates the synonym dictionary of your Elasticsearch cluster based on the file. The updated synonym dictionary can be used to accelerate your queries.

  • Configure a garbage collector

    Switch between the CMS and G1 garbage collectors.

  • Configure YML files

    Modify the YML settings of your Elasticsearch cluster. For example, modify the settings to allow automatic index creation, specified index deletion, audit log indexing configuration, watcher enabling, and other configurations.
