Amazon OpenSearch Service adds a new connection mode for cross-cluster connection, simplifying the setup required to remote reindex between a local domain and a remote VPC domains. Remote reindex enables you to migrate data from a source domain to a target domain. Remote reindex is also useful when you have to upgrade your domains across multiple major versions.
Previously, to use remote reindex, you ensured that the source domain was accessible from the target domain. If the remote domain was VPC enabled, you set up a publicly accessible reverse proxy for the remote domain, even if when the domains were located within the same VPC.
With this release, you create a new connection between a local domain and a remote VPC domains using the connection mode ‘VPC endpoint’, and then use the provided endpoint in the remote reindex operation. This will do away with the need for a proxy and will also ensure that the traffic between the domains remain within the Amazon Networking Backbone -- at no extra cost. The new connection mode is available for local domains running OpenSearch versions 1.3 and above. To learn more about the new connection mode and how to use it for remote reindex please refer to the documentation.
The new connection mode for cross-cluster connection is now available for Amazon OpenSearch Service domains in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD.
