First line of files will be used to name columns and will not be included in data.

Quote character
Quote character (delimiters inside quotes are ignored).
Escape character
Escape character (escaped quote characters are ignored).
Determines the parsing mode. By default it is PERMISSIVE.
  • PERMISSIVE: tries to parse all lines: nulls are inserted for missing tokens and extra tokens are ignored.
  • DROPMALFORMED: drops lines which have fewer or more tokens than expected or tokens which do not match the schema.
  • FAILFAST: aborts with a RuntimeException if encounters any malformed line.
Valid charset name (see java.nio.charset.Charset).
Automatically infers column types. It requires one extra pass over the data. All types will be assumed string otherwise.
Skip lines beginning with this character.
Null value
Specifies a string that indicates a null value, any fields matching this string will be set as nulls in the DataFrame.
Date format
Specifies a string that indicates the date format to use when reading dates or timestamps. Custom date formats follow the formats at java.text.SimpleDateFormat. This applies to both DateType and TimestampType. By default, it is null which means trying to parse times and date by java.sql.Timestamp.valueOf() and java.sql.Date.valueOf().
