trait SupportsOverwriteV2 extends WriteBuilder with SupportsTruncate
Write builder trait for tables that support overwrite by filter.
Overwriting data by filter will delete any data that matches the filter and replace it with data that is committed in the write.

Abstract Value Members
- abstract def overwrite(predicates: Array[Predicate]): WriteBuilder
Configures a write to replace data matching the filters with data committed in the write.
Configures a write to replace data matching the filters with data committed in the write.
Rows must be deleted from the data source if and only if all of the filters match. That is, filters must be interpreted as ANDed together.
- predicates
filters used to match data to overwrite
- returns
this write builder for method chaining

- def canOverwrite(predicates: Array[Predicate]): Boolean
Checks whether it is possible to overwrite data from a data source table that matches filter expressions.
Checks whether it is possible to overwrite data from a data source table that matches filter expressions.
Rows should be overwritten 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.
- predicates
V2 filter expressions, used to match data to overwrite
- returns
true if the delete operation can be performed
