**WIP: getting draft up now. Need to add a test and documentation. Then will mark ready for review.** # Which issue does this PR close? This is a change required in order to slice the row cursor in the [cascaded sort order](https://github.com/apache/arrow-datafusion/pull/7379). precursor for https://github.com/apache/arrow-datafusion/issues/7181 # Rationale for this change During the cascaded merge, we may yield partial record batch (a.k.a. partial cursors) from a given merge node (in the cascade tree). As such, the cursor would need to be sliced as [described here](https://github.com/apache/arrow-datafusion/blob/d52049675ee5c335285635aea984d51b7cca9f74/datafusion/core/src/physical_plan/sorts/builder.rs#L170). # What changes are included in this PR? Slicing the cursor. # Are there any user-facing changes? No breaking changes. Only a new API `.slice()` method. -- This is an automated message from the Apache Git Service.
