IMPALA-10323: use snprintf instead of lexical_cast to cast to string Like issue IMPALA-1738, using snprintf instead of lexical_cast when casting to string, performance can be improved significantly in multi-thread mode(mt_dop mode). In contrast, performance using lexical_cast decreased seriously in multi-thread mode.
