> * We recently found several issues with integer overflows: IMPALA-4995, IMPALA-4997, IMPALA-5021. To reduce the likelihood of similar issues we should make sure that all variables which store either a number of rows, number of tuples, or a number of bytes are of type int64_t.
> Here are some useful commands to find candidates:
> {noformat}
> git grep -E "^ +int(|32_t) .*row"
> git grep -E "^ +int(|32_t) .*tuple"
> git grep -E "^ +int(|32_t) .*num_"
> git grep -E "^ +int(|32_t) .*bytes"
> git grep -E "^ +int(|32_t) .*size"
> {noformat}
