Terraform will perform the following actions:

  # elasticstack_elasticsearch_index_lifecycle.apm_traces will be updated in-place
  ~ resource "elasticstack_elasticsearch_index_lifecycle" "apm_traces" {
        id            = "J6V5gvONTve393_OJiiJnA/weco-traces-apm"
        name          = "weco-traces-apm"
        # (1 unchanged attribute hidden)

      ~ delete {
            # (1 unchanged attribute hidden)

          + delete {
              + delete_searchable_snapshot = true
            }
        }

        # (1 unchanged block hidden)
    }

  # elasticstack_elasticsearch_index_lifecycle.apm_traces_rum will be updated in-place
