to use S3 and other S3-compatible object stores such as MinIO. MapReduce workloads typically interact with object stores in the same way they do with HDFS. These workloads rely on HDFS atomic rename functionality to complete writing data to the datastore. Object storage operations are atomic by nature and they do not require/implement rename API. The default S3A committer emulates renames through copy and delete APIs. This interaction pattern causes significant loss of performance because of the...

- **Elasticsearch / OpenSearch** - Direct data migration via bulk APIs
- **Apache Solr** - Document import via REST API
- **Database Systems** - Direct connection via DataStore plugins
- **File Systems** - SMB, FTP, local file crawling
- **Custom Systems** - REST API for bulk document indexing
