Rollup Job with an alias?

Is it possible to create a rollup job and have the target index be an alias? I tried to do this but the rollup job fails to create the index (due to an alias having the same name already existing).

Goal: I want a rollup job to run daily and adds data to a index(or alias). And when the index hits a certain limit min size or min age it rolls over to a new index.

Any ideas?

Did you make it? I would also like to do a roll over of rollup indexes.

Hey guys, any luck? I also want to do this.

Yes you can do this since 2.5 or 2.6. You just have to create index with alias attached, before creating rollup job:

PUT /myindex-00001
{
  "aliases": {
    "myalias": {
      "is_write_index": true
      }
    }
  }
}

then you can create rollup job and use myalias as target_index
