Hello, we use Amazon AWS as a hosting providers. Currently we are in single availability zone and have plans to scale up to more of them. What would be the best practices to do that? What impact on performance shards spread on different DCs have? If we duplicate indexes on all DCs what would be the best way to keep them all in sync and up to date? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
