Thanks a lot for the quick response and the godbolt example. It seems this is failing even with the older compiler versions that we used. Perhaps an issue in https://github.com/r-lib/cpp11 is warranted? I also ended up looking through the changes from r-cpp11 and couldn't find somet...
become even more important than the twist-2 contributions in a few\mathrm {GeV}region. Transforming the matrix element of the bilocal operator in Eq. (6) from the coordinate space into the momentum space, one can obtain the light-cone projection operator [34,41,42] (8) with\Psi _{\pi...
As the original author of bothread_csvandHDFStore, these benchmarks make me very proud, but it also shows what level of data access performance pandas users should expect in general. The price of data serialization can be directly seen in the Impala query profile (note, this is a DEBUG Im...

Thus, for example, when DataFusion uses the arrow::compute::limit operator to return a few elements of an array, we still end up with a the full (potentially) large array being sent over the wire. Since encoding the array in a FlightData involves copying the data anyway, perhaps it wou...
