## What is Amazon OpenSearch Serverless?

* **Note**\
  Collections with unique AWS KMS keys can't share OCUs with other collections.

## Managing capacity limits

* **Note**\
  Although capacity can scale up to accomodate data, it can't currently scale up *search* replicas. OpenSearch Serverless functions with two search replicas running in active-active mode. If you need more replicas for your workload, contact [AWS Support](https://console.aws.amazon.com/support/home).
* **Note**\
  At this time, capacity settings only apply at the account level. You can't configure per-collection capacity limits.

## Ingesting data into collections

* **Note**\
  You must have version 2.30.0 or later of the AWS for Fluent Bit image in order to integrate with OpenSearch Serverless.
