Custom packages

• Tip Dictionary files use Java heap space proportional to their size. For example, a 2 GiB dictionary file might consume 2 GiB of heap space on a node. If you use large files, ensure that your nodes have enough heap space to accommodate them. Monitor the JVMMemoryPressure metric, and scale your cluster as necessary.

• Note If you receive a "package not found" error when you run the script using the AWS CLI, it likely means Boto3 is using whichever Region is specified in ~/.aws/config, which isn't the Region your S3 bucket is in. Either run aws configure and specify the correct Region, or explicitly add the Region to the client:

SQL support

• Note If your domain is running Elasticsearch rather than OpenSearch, the format is _opendistro/_sql.

Cross-cluster search

• Note If you include remote indexes in the path, you must URL-encode the URI in the domain ARN. For example, use arn:aws:es:us-east-1:123456789012:domain/my-domain/local_index,dst%3Aremote_index rather than arn:aws:es:us-east-1:123456789012:domain/my-domain/local_index,dst:remote_index.

• Note All cross-cluster search requests between domains are encrypted in transit by default as part of node-to-node encryption.

Learning to Rank

• Note To use the Learning to Rank plugin, you must have full admin permissions. To learn more, see Modifying the master user.

• Note You must perform this step outside of OpenSearch Service.

• Note You must perform this step outside of OpenSearch Service.

• Note You must perform this step outside of OpenSearch Service.

Asynchronous search

• Note If you're using Elasticsearch 7.10 instead of an OpenSearch version, replace _plugins with _opendistro in all asynchronous search requests.

• Note All request parameters that apply to a standard _search query are supported. If you're using Elasticsearch 7.10 instead of an OpenSearch version, replace _plugins with _opendistro.

• Note You can monitor asynchronous search statistics in CloudWatch. For a full list of metrics, see Asynchronous search metrics.

Point in time

• Note You can monitor PIT search statistics in CloudWatch. For a full list of metrics, see Point in time metrics.
