需要在 6.2.4 elasticsearch 中重命名索引

Question

I have used _shrink api and shrinked my index from 5shards to 1 shard but with a different name and have deleted the old index. Now I want to rename the newly created index to the same old name, used _reindex api but that is creating the index with same old 5shards, but want to have it on single primary shard. Since am in 6.2.4 can't use _clone api.

Please advise. TIA

Answer 1

Add the amount of shards at index creation time:

PUT /my-index-000001
{
  "settings": {
    "index": {
      "number_of_shards": 1
    }
  }
}

You can also add the mapping and other settings in this request.
