AliES is a highly tailored kernel for Alibaba Cloud Elasticsearch and supports all features provided by the open source Elasticsearch kernel. AliES also provides additional features, such as monitoring metric optimization, thread pooling and circuit breaking optimization, and query and write performance optimization. These additional features are developed based on the abundant experience of the Alibaba Cloud Elasticsearch team from multiple scenarios.
