  5. def async : MergeBuilderAsyncActor

    Returns a MergeBuilderAsyncActor object that can be used to execute MergeBuilder actions asynchronously.

    Returns a MergeBuilderAsyncActor object that can be used to execute MergeBuilder actions asynchronously.

    Example:

    val target = session.table(tableName)
    val source = Seq((10, "new")).toDF("id", "desc")
    val asyncJob = target
      .merge(source, target("id") === source("id"))
      .whenMatched
      .update(Map(target("desc") -> source("desc")))
      .async
      .collect()
    // At this point, the thread is not blocked. You can perform additional work before
    // calling asyncJob.getResult() to retrieve the results of the action.
    // NOTE: getResult() is a blocking call.
    val mergeResult = asyncJob.getResult()
    returns

    A MergeBuilderAsyncActor object

  22. def whenMatched ( condition: Column ) : MatchedClauseBuilder

    Adds a matched clause into the merge action.

    Adds a matched clause into the merge action. It matches all rows in target that satisfy <joinExpr> while also satisfying <condition>. Returns a MatchedClauseBuilder which provides APIs to define actions to take when a row is matched.

    For example:

    target.merge(source, target("id") === source("id")).whenMatched(target("value") === lit(0))

    Adds a matched clause where a row in the Updatable target is matched if its id equals the id of a row in the DataFrame source and its value equals 0.

    returns

    MatchedClauseBuilder

    Since

    0.7.0

  23. def whenMatched : MatchedClauseBuilder

    Adds a matched clause into the merge action.

    Adds a matched clause into the merge action. It matches all remaining rows in target that satisfy <joinExpr>. Returns a MatchedClauseBuilder which provides APIs to define actions to take when a row is matched.

    For example:

    target.merge(source, target("id") === source("id")).whenMatched

    Adds a matched clause where a row in the Updatable target is matched if its id equals the id of a row in the DataFrame source.

    Caution: Since it matches all remaining rows, no more whenMatched calls will be accepted beyond this call.

    returns

    MatchedClauseBuilder

    Since

    0.7.0

  24. def whenNotMatched ( condition: Column ) : NotMatchedClauseBuilder

    Adds a not matched clause into the merge action.

    Adds a not matched clause into the merge action. It matches all rows in source that do not satisfy <joinExpr> but satisfy <condition>. Returns a MatchedClauseBuilder which provides APIs to define actions to take when a row is matched.

    For example:

    target.merge(source, target("id") === source("id"))
    .whenNotMatched(source("value") === lit(0))

    Adds a not matched clause where a row in the DataFrame source is not matched if its id does not equal the id of any row in the Updatable source and its value equals 0.

    returns

    NotMatchedClauseBuilder

    Since

    0.7.0

  25. def whenNotMatched : NotMatchedClauseBuilder

    Adds a not matched clause into the merge action.

    Adds a not matched clause into the merge action. It matches all remaining rows in source that do not satisfy <joinExpr>. Returns a MatchedClauseBuilder which provides APIs to define actions to take when a row is not matched.

    For example:

    target.merge(source, target("id") === source("id")).whenNotMatched

    Adds a not matched clause where a row in the DataFrame source is not matched if its id does not equal the id of any row in the Updatable target.

    Caution: Since it matches all remaining rows, no more whenNotMatched calls will be accepted beyond this call.

    returns

    NotMatchedClauseBuilder
