  • Question on sorting a large partitioned table

    Posted by jackyyuk on December 4, 2023 at 12:00 am


    Currently, I would like to sort a partitioned table by its column colA and colB. I simple perform the following actions:

    { t:`colA`colB xasc select from `:<dir_source>/<date>/<trade>;

    (`:<dir_destination>/<date>/<trade>;17;2;6) set t} for each dates

    However, the q service was killed occasionally due to memory usage, as some the table data is very large.

    Is there anyway to reduce the memory usage, and prevent the killing?
