Amazon OpenSearch Service quotas - Amazon OpenSearch Service

Amazon OpenSearch Service quotas

Your AWS account has default quotas, formerly referred to as limits, for each AWS service. Unless otherwise noted, each quota is Region-specific.

To view the quotas for OpenSearch Service, open the Service Quotas console. In the navigation pane, choose AWS services and select Amazon OpenSearch Service. To request a quota increase, see Requesting a quota increase in the Service Quotas User Guide.

Domain and instance quotas

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

Name Default Adjustable Notes
Dedicated master instances per domain 5 No You can use the T2 and T3 instance types for dedicated master nodes only if the number of data nodes is 10 or fewer.
Domains per Region 100 Yes
Instances per domain 80 Yes You can request an increase up to 200 instances. For example, your domain might have 80 data nodes and 120 warm nodes.
Instances per domain (T2 instance type) 10 No We don't recommend T2 or t3.small instance types for production domains.
Warm instances per domain 150 No

Your AWS account has the following additional 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

For a list of the instance types that OpenSearch Service supports, see Supported instance types.

UltraWarm storage quotas

The following table lists the UltraWarm instance types and the maximum amount of storage that each type can use. For more information about UltraWarm, see UltraWarm storage for Amazon OpenSearch Service.

Instance type Maximum storage
ultrawarm1.medium.search 1.5 TiB
ultrawarm1.large.search 20 TiB

EBS volume size quotas

The following table shows the minimum and maximum sizes for EBS volumes for each instance type that OpenSearch Service supports. For information about which instance types include instance storage and additional hardware details, see Amazon OpenSearch Service pricing.

  • If you choose magnetic storage under EBS volume type when creating your domain, the maximum volume size is 100 GiB for all instance types except t2.small and t2.medium, and all Graviton instances (M6g, C6g, R6g, and R6gd), which don't support magnetic storage. For the maximum sizes listed in the following table, choose one of the SSD options.

  • Some older-generation instance types include instance storage, but also support EBS storage. If you choose EBS storage for one of these instance types, the storage volumes are not additive. You can use either an EBS volume or the instance storage, not both.
