58.  def savePartition(table: String, iterator: Iterator[Row], rddSchema: StructType, insertStmt: String, batchSize: Int, dialect: JdbcDialect, isolationLevel: Int, options: JDBCOptions): Unit

    Saves a partition of a DataFrame to the JDBC database.

    Saves a partition of a DataFrame to the JDBC database. This is done in a single database transaction (unless isolation level is "NONE") in order to avoid repeatedly inserting data as much as possible.

    It is still theoretically possible for rows in a DataFrame to be inserted into the database more than once if a stage somehow fails after the commit occurs but before the stage can return successfully.

    This is not a closure inside saveTable() because apparently cosmetic implementation changes elsewhere might easily render such a closure non-Serializable. Instead, we explicitly close over all variables that are used.

    Note that this method records task output metrics. It assumes the method is running in a task. For now, we only records the number of rows being written because there's no good way to measure the total bytes being written. Only effective outputs are taken into account: for example, metric will not be updated if it supports transaction and transaction is rolled back, but metric will be updated even with error if it doesn't support transaction, as there're dirty outputs.

59.  def saveTable(df: DataFrame, tableSchema: Option[StructType], isCaseSensitive: Boolean, options: JdbcOptionsInWrite): Unit
