- * @param table the logical plan representing the table. In the future this
should be a

converge Hive tables
- * and data source tables.
- * @param partition a map from the partition key to the partition value
(optional). If the partition

performed.
- * As an example, `INSERT INTO tbl PARTITION (a=1, b=2) AS
...` would have
- * Map('a' -> Some('1'), 'b' -> Some('2')),
- * and `INSERT INTO tbl PARTITION (a=1, b) AS ...`
- * would have Map('a' -> Some('1'), 'b' -> None).
- * @param query the logical plan representing data to write to.
- * @param overwrite overwrite existing table or partitions.
- * @param ifPartitionNotExists If true, only write if the partition does not
exist.
- * Only valid for static partitions.

Review comment:
I saw these checks too in InsertIntoStatement.
