Elasticsearch (ES) replicates the clone index

[Copy link]
Posted on 1/28/2021 3:01:38 PM | | | |
Scenario: When operating on document data in ES, we may need to back up the data and use Elasticsearch (ES) to copy the clone index.

Method 1:

With the _reindex command, in its most basic form_reindex simply copying documents from one index to another. However, it does not copy the configuration information such as shard (shard) and replicas of the original index.



Method 2:

Use the clone command

To clone an index, it must be marked as read-only and the cluster health is green.

For example, the following request prevents a write operation on it, my_source_index can therefore clone it. Metadata changes, such as deleting indexes, are still allowed.
