How can I customize the Index codecs in the Index Setting of Graylog datanode?

[macaty]

OpenSearch already supports zstd Index codecs. How can I set the corresponding setting in Graylog datanode?

• Graylog Version: 6.0

Can we post the setting via http://127.0.0.1:9000/api/system/indexer/indices/templates/66f4d189828e122f3602b271/update?

You can interact directly with OpenSearch by using Data Node to generate an auth certificate and then authenticating with that cert. See https://go2docs.graylog.org/current/downloading_and_installing_graylog/install_graylog_data_node.htm?Highlight=data%20node#CreateClientCertificateforThirdPartyTools

Thank you very much, I have created the access key and can query the index template. how can i setting index template?

When I finish the index setting: "codec" : "best_compression",

When rotating Nginx indices after clicking the 'Rotate active write index' button, the settings revert to default instead of retaining the custom settings.
