-----------------------------------
Attachment: DRILL-1960.patch
> Automatically realloc buffers when vector runs out of space
> -----------------------------------------------------------

> Key: DRILL-1960

>
> When reaching the end of a buffer, the current way drill handles this is for
> setSafe() to return false, and then whatever operator is doing the write will
> send the batch, and the redo the last record. This creates a lot of
> difficulty, because it sometimes requires being able to "rewind" the input
> stream to replay the last record.
> The proposal is to move the handling of buffer sizing and allocation into the
> value vectors themselves, making it transparent to the user of the value
> vector. The operators will now no longer have to worry about the possibility
> that writing into a vector may fail due to lack of space.
