ramkrishna.s.vasudevan commented on PHOENIX-37:
-----------------------------------------------

{code}
int elemLength = bytes[currOffset] == SEPARATOR_BYTE ?
    0 : getOffsetFor(elemPosition+1) - currOffset - 1; 
{code}
Will need a bit of modification here.  Will come up with a patch after 
updating.  Because in case of an element followed by null the elementlength is 
actually not 0. Will submit a new patch soon.

> Prevent deserialize and re-serialize all array elements in construction of 
> array

> ArrayConstructorExpression.evaluate() currently deserializes into object form 
> all array elements only to serialize them back again as bytes. Instead, just 
> use a TrustedByteArrayOuputStream (initially sized based on the number of 
> child elements) to serialize the data into. If variable length, track the 
> offset information as the data is written.
> Second, we should put the header information (offsets, length, and version) 
> at the end of the array instead of the start. This will make it possible to 
> compare arrays against each other in their byte form.
