# Amazon OpenSearch Service endpoints and quotas
<a name="opensearch-service"></a>

To connect programmatically to an AWS service, you use an endpoint. AWS services offer the following endpoint types in some or all of the AWS Regions that the service supports: IPv4 endpoints, dual-stack endpoints, and FIPS endpoints. Some services provide global endpoints. For more information, see [AWS service endpoints](rande.md).

Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see [AWS service quotas](aws_service_limits.md).

The following are the service endpoints and service quotas for this service.

## Service quotas
<a name="opensearch-limits"></a>

For more information, see [Amazon OpenSearch Service quotas](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/limits.html).

### OpenSearch Service domain and instance quotas
<a name="opensearch-limits-domain"></a>

Your AWS account has the following quotas related to OpenSearch Service domains:


| Name | Default | Adjustable | Description | 
| --- | --- | --- | --- | 
| Dedicated master instances per domain | Each supported Region: 5 | No | The maximum number of dedicated master instances in a single Amazon OpenSearch Service domain. | 
| Domains per Region | Each supported Region: 500 |  [Yes](https://console.aws.amazon.com/servicequotas/home/services/es/quotas/L-076D529E)  | The maximum number of Amazon OpenSearch Service domains you can create in each AWS Region. | 
| Instances per domain | Each supported Region: 200 |  [Yes](https://console.aws.amazon.com/servicequotas/home/services/es/quotas/L-6408ABDE)  | The maximum number of instances in a single Amazon OpenSearch Service domain. You can request an increase up to 1002 instances per domain. | 
| Instances per domain (T2 instance type) | Each supported Region: 10 | No | The maximum number of T2 instances in a single Amazon OpenSearch Service domain. | 
| Warm instances per domain | Each supported Region: 150 | No | The maximum number of warm nodes in a single Amazon OpenSearch Service cluster. | 

Your AWS account has the following additional OpenSearch Service limits:


| Name | Default | Adjustable | Notes | 
| --- | --- | --- | --- | 
| Total storage per domain | 3 PiB | No | This maximum is the sum of all data nodes and warm nodes. For example, your domain might have 45 r6gd.16xlarge.search instances and 140 ultrawarm1.large.search instances for a total of 2.88 PiB of storage. | 
| Custom packages per Region | 25 | No |  | 
| Custom packages per domain | 20 | No |  | 

### OpenSearch Serverless quotas
<a name="opensearch-limits-serverless"></a>

Your AWS account has the following quotas related to OpenSearch Serverless resources.

To view the quotas for OpenSearch Serverless, open the [Service Quotas console](https://console.aws.amazon.com/servicequotas/home). In the navigation pane, choose **AWS services** and select **Amazon OpenSearch Serverless**.


| Name | Default | Adjustable | Notes | 
| --- | --- | --- | --- | 
| Default indexing capacity (OCUs) | 10 | No |  | 
| Default search capacity (OCUs) | 10 | No |  | 
| Maximum indexing capacity (OCUs) | 1,700 | No |  | 
| Maximum search capacity (OCUs) | 1,700 | No |  | 
| Data access policies | 500 | No |  | 
| Encryption policies | 150 | No |  | 
| Network policies | 500 | No |  | 
| SAML providers | 50 | No |  | 
| Data access policy size | 10,240 bytes | No |  | 
| Network policy size | 10,240 bytes | No |  | 
| SAML provider size | 51,200 bytes | No |  | 
| Encryption policy size | 10,240 bytes | No |  | 

Your AWS account has the following additional OpenSearch Serverless limits:


| Name | Default | Adjustable | Notes | 
| --- | --- | --- | --- | 
| Collection tags | 50 | No |  | 
| Collections per collection group | 1,500 | No | The maximum number of collections per collection group. The actual number of collections can be further limited by MaxOCUs based on the size of collections. | 
| Collections with unique KMS keys (not in a collection group) | Maximum OCU/2 | No | This limit only applies to collections that are not part of a collection group. It depends on the maximum number of OCUs you set and how many OCUs are already in use. Collections within a collection group have a separate limit of 1,500 collections per group, regardless of the number of unique KMS keys used. | 
| OpenSearch Serverless-managed VPC endpoints | 50 | No | This limit only applies to OpenSearch Serverless-managed VPC endpoints. It doesn't include OpenSearch Service-managed VPC endpoints. | 
| Indexes per Amazon OpenSearch Serverless collection | 1000 | No | The maximum number of indexes per Amazon OpenSearch Serverless collection is 1000. | 
| Index templates per Amazon OpenSearch Serverless collection | 500 | No | The maximum number of index templates per Amazon OpenSearch Serverless collection is 500. | 
| Maximum collection groups | 300 | No | The maximum number of collection groups per account. | 

### OpenSearch Ingestion quotas
<a name="opensearch-limits-serverless"></a>

Your AWS account has the following quotas related to OpenSearch Ingestion resources. Unless otherwise noted, each quota is Region-specific.


| Name | Default | Adjustable | Notes | 
| --- | --- | --- | --- | 
| Connected VPCs per pipeline | Each supported Region: 1 | No |  | 
| Pipelines connected to a single VPC domain | Each supported Region: 50 | No |  | 
| Pipelines | Each supported Region: 50 | No |  | 
| Characters per pipeline configuration | Each supported Region: 24000 | No |  | 
| Sources per pipeline | Each supported Region: 100000 | No | This limit only applies to *plugin* sources, such as HTTP, OTel, or S3. You can still chain sub-pipelines together within a single OpenSearch Ingestion pipeline configuration. | 
| Unique OpenSearch sinks per pipeline | Each supported Region: 1 | No | This limit only applies to OpenSearch *domain* and *collection* sinks. You can still chain sub-pipelines together within a single OpenSearch Ingestion pipeline configuration. | 
| Total OpenSearch sinks per pipeline | Each supported Region: 50 | No | This limit refers to the number of times that you can specify the same OpenSearch sink within a pipeline configuration file.
