Example 1 with ElasticsearchIndicesClient

use of co.elastic.clients.elasticsearch.indices.ElasticsearchIndicesClient in project core-ng-project by neowu.

the class ElasticSearchImpl method putIndex.

// this is generally used in es migration, to create index or update mapping if index exists, be aware of mapping fields can't be deleted in es, but can be removed from mapping json
