Amazon OpenSearch Serverless now supports up to 10,000 collections per collection group

The next generation of Amazon OpenSearch Serverless now supports up to 10,000 collections within a single collection group, increased from the previous limit of 1,500. Collection groups organize multiple collections and enable them to share OpenSearch Compute Units (OCUs), even when the collections are encrypted with different AWS KMS keys. With this higher limit, you can consolidate significantly more collections into a single collection group and manage them under a shared set of capacity limits.
