Haoran Zhang commented on PHOENIX-154:
--------------------------------------
Dear James,
I'm Haoran Zhang, a Msc(Computing) student at Imperial College.
I had worked for about three years at Alibaba Group in the area of distributed
computing.
Here is my cv(www.doc.ic.ac.uk/~hz114/haoran_cv.pdf). Hopefully, this can make
you know me better.
I'm very keen to participate Google Summer of Code 2016 and this issue is very
interesting to me.
About this issue, I have a question. OLAP extensions are a big family and it is
quite impossible to support all of them in 12 weeks by one person. Moreover,
some OLAP functions may not suitable for Phoenix, as they may lead to numerous
data translation that may block the network and reduce the throughput.
I want to know could the student who is assigned to this issue only choose 4 or
5 OLAP functions to support?
In addition, would you mind giving any suggestions or materials for me to start
getting familiar with this issue to conduct a formal proposal?
Thank you very much.
