Backend.delimited_file(hdfs_dir, schema, name=None, database=None, delimiter=',', na_rep=None, escapechar=None, lineterminator=None, external=True, persist=False)

Interpret delimited text files (CSV / TSV / etc.) as an Ibis table. See parquet_file for more exposition on what happens under the hood.

  • hdfs_dir (string) – HDFS directory name containing delimited text files

  • schema (ibis Schema) –

  • name (string, default None) – Name for temporary or persistent table; otherwise random one generated

  • database (string) – Database to create the (possibly temporary) table in

  • delimiter (length-1 string, default ',') – Pass None if there is no delimiter

  • escapechar (length-1 string) – Character used to escape special characters

  • lineterminator (length-1 string) – Character used to delimit lines

  • external (boolean, default True) – Create table as EXTERNAL (data will not be deleted on drop). Not that if persist=False and external=False, whatever data you reference will be deleted

  • persist (boolean, default False) – If True, do not delete the table upon garbage collection of ibis table object
