No, we haven’t considered it yet. But it looks interesting.

Don’t understand me wrong, I like Phoenix. When it works, it is a great 
database and meets our requirements. But we didn’t get rid of the problems (and 
when I look at the answers from Jaanai and Flavio, we are not the only one). We 
hoped that with Phoenix 5 the problems are reduced, but at the moment it didn’t 
looks like.

We have not yet searched for alternatives, but are beginning to keep our eyes 
open.

Have you considered : CockRoach DB?

It is similar to Google Spanner but with soft clock mechanism.

Hi,

we are using Phoenix in production since more than 2 years. We are quite 
unhappy with the reliability of Phoenix. We migrated from Oracle because of the 
performance (we have tables with up to 200M records, each record up to 30 MB in 
size, up to 10 selective columns). Phoenix is really much faster than Oracle 
(20 nodes cluster).

But we have problems with

•         Phoenix totally hanging, only restart helps (We were able to reduce 
this from daily to monthly)

•         incorrect indices, need rebuild

•         select statements not producing the expected (specified) results

•         Upserts sporadically not working without error message

•         Some not reproducible errors

•         …

We are thinking about switching to another database, but the question is: what 
is better (reliable and performant)?

Conclusion: With the current status of Phoenix, I would never use it again.

Regards
Martin

I stumbled on this post:

and the bug:

   https://issues.apache.org/jira/browse/PHOENIX-5287

 I had a similar very frustrating experience with Phoenix, In addition to 
various performance issues, you can found one of my posts about the reliability 
issue on the mail-list.

https://lists.apache.org/thread.html/231b175fce8811d474cceb1fe270a3dd6b30c9eff2150ac42ddef0dc@%3Cuser.phoenix.apache.org%3E

 just wondering others experience if you could share
