| Elasticsearch Alias, allows me to re-index without disconnecting the clients. For example, I have an e-commerce that connects directly to elasticsearch. I use hibernate-search in my erp to index my records from the database (100000 records). But when doing reindex, hibernate-search deletes the records and inserts them again. It would be cool to have a unique option to recreate the data in another index and after it has finished pointing to the alias. Allowing zero downtime. Example: On create:
1- my_index(alias) — > my_index_v1
2- add new records (100000 records) in my_index_v1 On update (reindex):
1- my_index(alias) — > my_index_v1
2- add new records (100000 records) in my_index_v2
3 - change my_index(alias) — > my_index_v2
4 - remove and delete my_index_v1 Index Aliases (Guide):
