Hello Prakash Considering Hive or Phoenix is a little misleading they di serve different needs, let me break it down as I can.
You mention security: Phoenix and hive both work on a secured Hadoop cluster, but Hive with Hive Atz has a more fine grained authorization model. So from that perspective Hive has more features. Query performance On the performance side Phoenix has random read,write access where Hive is a full data access, so no way to read a particular entry unless you read the whole associated file. So Hive is batch or interactive, meaning a couple of tens of seconds to get your answer, where Phoenix can be sub second, the response time will depend greatly on wether part of the pheonix key is in your query. I you do a full table scan response time will suffer. Granted secondary indexes could help you there. SQL Semantics Hive currently has a more rich sql semantics with analytics functions, complex types etc... Phoenix is also more limited than Hive in joins or UDFS So I would use Hive for large data, random analysis and ETL, and pay the price of the response time a little. Phoenix on the other hand is great for large volumes of data where you can set up your schema and especially keys according to specific needs and query patterns, in this situation you would get great query performance. To sum up in all honesty both are needed Hope this helps On Tue, Sep 9, 2014 at 4:19 PM, Prakash Hosalli <prakash.hosa...@syncoms.com > wrote: > > > Hi, > > > > > > Is phoenix as any security layer in it.
