</div></div>
<p id="EN-US_TOPIC_0000002333390490__p1529111251215">OpenSearch uses an LSM (Log-Structured Merge) tree-like model to accelerate write operations. As data is continuously written in and updated, numerous small index segments are generated and later merged via a backend task to enhance query performance. As vector indexing is computationally intensive, frequent index merging while vector data is being written in consumes significant CPU resources. Therefore, where real-time data is not crucial, it is advisable to set <strong id="EN-US_TOPIC_0000002333390490__b114183182411171">lazy_indexing</strong> to <strong id="EN-US_TOPIC_0000002333390490__b174512243911171">true</strong> for vector fields. This allows a final vector index to be created via a non-real time API after all data has been written in. This approach significantly reduces index merges, thereby improving overall write and index merging performance.</p>
<p id="EN-US_TOPIC_0000002333390490__p031561711139">Offline index building consists of two steps:</p>

<p id="EN-US_TOPIC_0000002333390490__p1367412481662">The API used for offline index building is as follows:</p>

Cerebro works for OpenSearch just as well. In CSS, Cerebro is pre-built for each OpenSearch cluster. You can start Cerebro with one click, without installing anything. Cerebro allows you to quickly check a cluster's health status, node distribution, and index details. For routine O&amp;M tasks, including shard adjustment, index management, and performance monitoring, we recommend using Cerebro. Its intuitive cluster topology views and comprehensive management features streamline O&amp;M workflows, reducing complexity while improving efficiency. Cerebro is suitable for different roles, including developers, O&amp;M teams, and data analysts.</p>
