Arrow Flight Table Function

Allows to perform queries on data exposed via an Apache Arrow Flight server.

Syntax

arrowFlight('host:port', 'dataset_name' [, 'username', 'password'])

Arguments

  • host:port — Address of the Arrow Flight server. String.
  • dataset_name — Name of the dataset or descriptor available on the Arrow Flight server. String.
  • username - Username to use with basic HTTP style authentication.
  • password - Password to use with basic HTTP style authentication. If username and password are not specified, it means that authentication is not used (that will work only if the Arrow Flight server allows it).

Returned value

  • A table object representing the remote dataset. The schema is inferred from the Arrow Flight response.

Example

Query:

SELECT * FROM arrowFlight('127.0.0.1:9005', 'sample_dataset') ORDER BY id;

Result:

┌─id─┬─name────┬─value─┐
│  1 │ foo     │ 42.1  │
│  2 │ bar     │ 13.3  │
│  3 │ baz     │ 77.0  │
└────┴─────────┴───────┘
