Elasticsearch vs Amazon OpenSearch​

Bedrock OpenSearch​

  • AWS OpenSearch SearchOCU keeps hitting the max limit | AWS re:Post
    • My OpenSearch domain exhibited unexpected Search Capacity Unit (SearchOCU) scaling behavior correlated with the number of Collections, even with minimal query activity. After deleting a large number of Collections, retaining only critical Collections totaling less than 5GB, the SearchOCU count decreased to 2. Previously, with a significantly higher number of Collections, the SearchOCU count was substantially inflated, despite low query volume.
    • This observation suggests that the sheer presence of a large number of OpenSearch Collections, independent of active search queries, influences SearchOCU consumption. While I understand the impact of query load on scaling, the mechanism by which the number of Collections drives SearchOCU inflation remains unclear.
