On main branch,
Tables.partitions
fails on table with more than 10 columns. The (somewhat convoluted) reason is that juliantuple
function when fed aUInt64
as second argument, casts it toInt
only if it is<= 10
(see JuliaLang/julia#55790). This works in our favor for smalln
(number of columns), as the functionColumnConversionData
expects aInt
, not aUInt64
, but for largern
attempting to collect aTables.partitions
fails.The first commits is a minimal fix + test, whereas the second commit also adds a small refactor to simplify code and make it more robust to this.
