[Discuss] Enhancements to external sort

[Paul Rogers <pr...@maprtech.com>]

Hi All,

We’re looking at some improvements to the external sort operator, primarily to better control the amount of memory that the operator requires. DRILL-5080 is the umbrella ticket. Attached to that ticket is a design document that details both the issues we wish to address and how we propose to address them.

Please have a look at the design and offer suggestions. In particular, if any of you have experience with this operator, your insight into the revised design would be very helpful.

Thanks,

- Paul
