Managing indexes in Amazon OpenSearch Service

After you add data to Amazon OpenSearch Service, you often need to reindex that data, work with index aliases, move an index to more cost-effective storage, or delete it altogether. This chapter covers storage tiering solutions, Index State Management, and other index operations. For information on the OpenSearch index APIs, see the OpenSearch documentation.
