Phoenix Array
Hi at all,
I use Apache Phoenix from some months and I appreciate this project. I
would like to know if Array DataType has any limitation.
Best,
Davide

Hi Jamex,
you right is don't read the limitation:
- Partial update of an array is currently not possible. Instead, the
array may be manipulated on the client-side and then upserted back in its
entirety.
I am very sorry
Best,
Davide

Hi Nick,
ths for your response. Due to the fact that an array is saved physically in
a single cell on HBase. I think that if my Array overcome the max size I
receive an error. Is it true? Can I incrementally add element single in the
array?

One thing to keep in mind is that all of the array elements are stored in a
single cell. As long as the combined size of all elements is less than what
HBase is happy with for a cell, you should be fine. Also, FWIW, references
to a single element are optimized to only return that element on selects.
Thanks,
James

Hi Davide,
I'm glad Phoenix is working well for you. Can you be more specific with
your question? What kind of limitations are you concerned about? Have you
seen the ARRAY Type documentation? It outlines some limitations at the
bottom on the page.
