James Taylor commented on PHOENIX-37:
-------------------------------------
Yes, serializing directly with the byte arrays from the children. Also, to
change the format of the serialization by putting the header info at the end
instead of the beginning.
> Prevent deserialize and re-serialize all array elements in construction of
> array

> Key: PHOENIX-37
> URL: https://issues.apache.org/jira/browse/PHOENIX-37
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: James Taylor
> Assignee: ramkrishna.s.vasudevan
> Fix For: 3.0.0
>
>
> 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.
