> For Arrow's RecordBatchReader it probably doesn't care about being called from the R main thread but maybe does care about all the calls coming from the same thread? Generally speaking, iterators, readers, etc. (anything that is keeping some kind of internal pointer to a position in some source stream) is not going to be thread safe in Arrow-C++ unless it specifically says otherwise (and I can't think of any that do). That being said, access from multiple threads is probably ok as long as you protect the access with a mutex. -- This is an automated message from the Apache Git Service.
