Vespa CLI provides a high performance feed client through its feed command. The client feeds documents concurrently, with retries and dynamic throttling.

The input files for the feed command are expected to contain either a JSON array of feed operations, or one JSON operation per line (JSONL).
vespa feed uses the Document API, which must be enabled in the container before documents can be fed.

Examples

Feed documents from files or standard in:

$ vespa feed docs1.json docs2.json
$ cat docs.json | vespa feed -

Display a periodic summary (every 3 seconds) while feeding:

$ vespa feed --progress=3 docs.json

Print successful operations:

$ vespa feed --verbose docs.json

Copy documents from one cluster to another:

vespa visit --target http://localhost:8080 | vespa feed --target http://localhost:9090 -

See vespa help feed or man vespa-feed for complete usage.
