Can AWS glue bookmark column (for jdbc)have null value?


Hi, just wanted to know if aws glue bookmark columns can have null values - if null value is not supported, can anyone point to appropriate aws documentation for that?

Thank you!

The condition is that the column (or columns) must be monotonically increasing, a column with NULL values doesn't meet that condition because a NULL cannot be compared to other number and define which is higher or lower.
