Just to add to James' comment, they're indeed complementary and it all
comes down to your own use case. Phoenix offers a convenient SQL interface
over HBase, which is capable of doing very fast queries. If you're just
doing insert / retrieval, it's unlikely that Spark will help you much there.
It's not an either/or with Phoenix and Spark - often companies use both as
they're very complementary. See this [1] blog for an example. Spark is a
processing engine while Phoenix+HBase is a database/store. You'll need to
store your data somewhere.
Thanks,

Thank you. For a project as big as Facebook or Snapschat, would you
recommend using Spark or Phoenix for things such as message
retrieval/insert, user search, user feeds retrieval/insert, etc. and what
are the pros and cons?

Spark has a robust execution model with the following features that are not
part of phoenix
* Scalable
* fault tolerance with lineage (Handles large intermediate results)
* memory management for tasks
* Resource Management (Fair Scheduling)
* Additional
Hi everyone
I used varchar in phoenix to record string.But one the page of help ,I
can't find how many bytes can varchar contain. So i tried to write a very
large text to it, and I got The data exceeds the max capacity for the data
type.
Maybe I should use varbinary, but i still can't
I realized there is a spark plugin for phoenix, any use cases? why would I
use spark with phoenix instead of phoenix by itself?
