email@example.com produced a bug report on the mailinglist.
I am trying to evaluate the performance of MonetDB for an analytical workload.
I am using MonetDB-11.15.17 built from source on Ubuntu 13.04.
I have encountered a problem with user using defined functions in SQL which I have reduced to this test case.
First create a test data set with the following python:
Then I use the following to load the data, and try using a simple UDF in SQL.
The value returned my MY_UDF is null with 200,000 records, changing to 199,999 records in COPY INTO produces the correct result.
If I use a UDF built in C, the problem does not exist at all.
