elasticsearchHow do I export data from Elasticsearch?
To export data from Elasticsearch, you can use the Elasticsearch _export API. This API allows you to export the contents of an index in bulk.
For example, to export all data from an index called "my_index" using the _export
API, you can use the following command:
curl -X POST "localhost:9200/my_index/_export?pretty"
The output of this command will look something like this:
{
"took" : 0,
"timed_out" : false,
"_scroll_id" : "DnF1ZXJ5VGhlbkZldGNoBQAAAAAAAAGtOExXbVV3V0l5YXVmRVV4M0t4TnA3V2xnQQ==",
"exported_documents" : 0,
"total_exported_documents" : 0,
"batches" : 0
}
The _export
API supports a variety of parameters, such as scroll
, search_type
, fields
, size
, and sort
. These parameters can be used to customize the export process, such as limiting the number of documents returned, or sorting the documents before exporting.
For more information on the _export
API and its parameters, please refer to the Elasticsearch documentation.
