asfimport opened a new issue, #241:
URL: https://github.com/apache/arrow-java/issues/241
In several places in the Java codebase you can see this kind of pattern:
```java
while (vector.getDataBuffer().capacity() < toCapacity) {
vector.reallocDataBuffer();
}
```
In the event that a much larger capacity is requested, this will spuriously
make several reallocations (doubling the capacity each time).
It would probably be more efficient to reallocate directly to satisfy the
desired capacity.
Coincidentally, there's a `reallocDataBuffer` overload that seems to do just
that.
