Unfortunately we can't use TurboPFOR due to the licenses incompatibility issues. Manticore Columnar Library is based on Apache 2.0 while TurboPFOR is GPLv2

Please try select * from t where s = 'Psm' order by id asc limit 20 . Looks like the latest daemon commit indeed doesn't crash w/o explicit sorting, but does crash with sorting: snikolaev@dev2:~$ ~/manticore_github/build/src/searchd -c configless.conf …

@glookka is it clear from the output here https://github.com/manticoresoftware/columnar/actions/runs/11600797966/job/32302302075 why knn tests are skipped? Also, is it correct there's no lib_manticore_knn.dll here https://github.com/manticoresoftware/ …

We do use streamvbyte for 32-bit integers, but libfastpfor has other codecs that are also important and can't be built on ARM64. Best of all would be to port libfastpfor to ARM64.

Maybe we can use streamvbyte, which use Apache 2.0 License, and support arm64. It also suggested by the FastPFor library author, see https://github.com/lemire/FastPFor/issues/63#issuecomment-518646350
