Abstract Value Members

  1. abstract def deleteWhere(filters: Array[Filter]): Unit

    Delete data from a data source table that matches filter expressions.

    Delete data from a data source table that matches filter expressions.

    Rows are deleted from the data source iff all of the filter expressions match. That is, the expressions must be interpreted as a set of filters that are ANDed together.

    Implementations may reject a delete operation if the delete isn't possible without significant effort. For example, partitioned data sources may reject deletes that do not filter by partition columns because the filter may require rewriting files without deleted records. To reject a delete implementations should throw IllegalArgumentException with a clear error message that identifies which expression was rejected.

    filters

    filter expressions, used to select rows to delete when all expressions match

    Exceptions thrown

    IllegalArgumentException If the delete is rejected due to required effort
