Why have you split the alias update into two steps? It's both safer and faster to make it an atomic operation (see [Index Aliases](https://www.elastic.co/guide/en/elasticsearch/reference/6.3/indices-aliases.html)), e.g. ``` curl -X POST "localhost:9200/_aliases" -H 'Content-Type: application/json' -d' { "actions" : [ { "remove" : { "index" : "user-20180631", "alias" : "userdata" } }, { "add" : { "index" : "user-20180701", "alias" : "userdata" } } ] } ' ``` ---
