I updated the benchmark result and generated code.  
FYI: Since I update the benchmark result once with `UnsafeBufferWrite`, the 
performance is almost same.

LGTM

BTW, @kiszk have you updated the benchmark with newest change, especially 
after the UnsafeArrayData change?

@cloud-fan I rethought after changing `allowNull` to `isMapKey`, and 
finally I see what you said.

And we should revert the error message changes 4a0409a, right?

Github user cloud-fan commented on the issue:

https://github.com/apache/spark/pull/13909
  
I think the validation logic should be consistent across the system, you 
can't add the null check in `CreateArray` just because it's easy to do. 
Currently we do null check based on `nullable` property only at source side and 
we should follow it. And the previous code doesn't have null check either.

BTW, this change has external influence, the error message for null map key 
has been changed.

Github user ueshin commented on the issue:

https://github.com/apache/spark/pull/13909
  
@cloud-fan Hmm, I didn't mean we don't trust the source side.

Currently we DO validate the null regardless of `allowNull` value.
The difference by the `allowNull` is setting null or throwing an exception.
I think which we should do when `containsNull == false` is throwing an 
exception.

(Anyway, `eval.isNull` of most of children will be `"false"` when `nullable 
== false`, so Janino will remove the `$isNullAssignment` clause.

@ueshin That will be a big mess if we validate the null here and there, I 
think we should only do it at the source side. If we do not trust the source 
side, there are a lot of other places that need to add validation logic.

@cloud-fan Hmm, I agree that it's guaranteed by the source, but I thought 
that's why we should use `containsNull` for `allowNull` to guarantee the value 
will not be null when `containsNull == false` in this array for the caller of 
this expression. ditto for `CreateMap`.

> Should use dataType.containsNull for allowNull?

no we shouldn't,  `containsNull` is kind of an optimizing hint that 
guarantees the value will not be null, and it's guaranteed by the source, not 
here in `CreateArray`.

LGTM, I left some comments about code style, thanks for working on it!

BTW, can you update the benchmark result? I think we have finalized the 
solution now.

[GitHub] spark issue #13909: [SPARK-16213][SQL] Reduce runtime overhead of a program ...

2016-12-20 Thread cloud-fan
Github user cloud-fan commented on the issue:

https://github.com/apache/spark/pull/13909
  
sorry for the delay. Yea looks like we can't reuse the byte array of unsafe 
data in expressions, which may get cached expectedly and leads to wrong result.

I'm a little concerned about the hacks in `BufferHolder` and the array 
writer. The code is so coupled with unsafe row writer and we have to hack it so 
that we can write unsafe array directly. What if we actually write an unsafe 
row with a single array field and return the array column? Then we don't need 
the hacks, but waste some bits for the row format overhead, which seems 
acceptable.
