**Versions:** Amazon Opensearch Serverless **Issue** : I’m running into an issue with **Amazon OpenSearch Serverless** where my **Search OCUs are constantly hitting the maximum (32 OCUs)** which is 192 GB of RAM, even though I am not actively running any search queries and we do not have any users yet. **Configuration** : - Collection type: **Vector database** - Data size: ~ **115 GB** (vectorized data + metadata) - Number of shards: **2** - Data was fully indexed around **2 weeks ago** - **Indexing OCUs are stable** and not an issue - Only the **Search OCUs spike** continuously, leading to very high costs **Relevant Logs or Screenshots** : ![Screenshot 2025-08-23 at 2.36.21 PM](https://us1.discourse-cdn.com/flex019/uploads/mauve_hedgehog/original/2X/d/dc3fda1dba6c36dbb373502e4b2c019345dc4e4c.png) ---

@kiran Amazon OpenSearch Serverless is a managed AWS service. I think the best would be contacting AWS support to get best answer.
