[jira] [Updated] (PHOENIX-5044) Remove server side mutation code
from Phoenix
[ https://issues.apache.org/jira/browse/PHOENIX-5044?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lars Hofhansl updated PHOENIX-5044:
-----------------------------------
Description:
This is for *discussion*. Perhaps controversial.
It generally seems to be a bad idea - if well-intentioned - idea to trigger mutations directly from the server. The main causes are UPSERT SELECT for the same table and DELETE FROM.
IMHO, it's generally better to allow the client to handle this. There might be larger network overhead, but we get better chunking, better pacing, and behavior more in line with how HBase was intended to work.
In PHOENIX-5026 I introduced a flag to disable server triggered mutations in the two cases mentioned above. I now think it's better to just remove the server code and also perform these from the client.
(Not that server side reads - aggregation, filters, etc - are still insanely valuable and not affected by this)
Let's discuss.
