Abstract Value Members

  1. abstract def fallbackFileFormat: Class[_ <: FileFormat]

    Returns a V1 FileFormat class of the same file data source.

    Returns a V1 FileFormat class of the same file data source. This is a solution for the following cases: 1. File datasource V2 implementations cause regression. Users can disable the problematic data source via SQL configuration and fall back to FileFormat. 2. Catalog support is required, which is still under development for data source V2.

  2. abstract def getTable(options: CaseInsensitiveStringMap): Table
    Attributes
    protected
  3. abstract def shortName(): String

    The string that represents the format that this data source provider uses.

    The string that represents the format that this data source provider uses. This is overridden by children to provide a nice alias for the data source. For example:

    override def shortName(): String = "parquet"
