Amazon OpenSearch Ingestion increases memory for an OCU to 15 GB

We are pleased to announce that the memory allocation per OpenSearch Compute Unit (OCU) for Amazon OpenSearch Ingestion has been increased from 8GB to 15GB. One OCU now comes default with 2vCPU and 15GB of memory, allowing customers to leverage greater in-memory processing for their data ingestion pipelines without modifying existing configurations.

With the increased memory per OCU, Amazon OpenSearch Ingestion is better equipped to handle memory-intensive processing tasks such as trace analytics, aggregations, and enrichment operations. Customers can now build more complex and high-throughput ingestion pipelines with reduced risk of out-of-memory failures.

The increased memory for OCUs are now available in all AWS Regions where Amazon OpenSearch Ingestion is currently offered at no additional cost. You can take advantage of these improvements by updating your existing pipelines or creating new pipelines through the Amazon OpenSearch Service console or APIs at no additional cost.
