If you are using phoenix 4.8 onwards then you can try giving zookeeper
string appended with a schema like below.
psql.py ;schema= /create_table.sql
psql.py zookeeer1;schema=TEST_SCHEMA /create_table.sql

bq. 1. How many concurrent phoenix connections the application can open?
I don't think there is any limit on this.
bq. 2. Is there any limitations regarding the number of connections I should
consider?
I think as many till your JVM permits.
bq. 3. Is the client side config parameter phoenix.que
It seems we don't pack the dependencies in phoenix-kafka jar yet. Try
including flume-ng-configuration-1.3.0.jar in your classpath to resolve the
above issue.

+1 for Joanthan comment,
-- Take multiple jstack of the client during the query time and check which
thread is working for long. If you find merge sort is the bottleneck then
removing salting and using SERIAL scan will help in the query given above.
Ensure that your queries are not causing hotspott
This is because we cap the scan with the current timestamp so anything
beyond the current time will not be seen. This is needed mainly to avoid
UPSERT SELECT to see its own new writes.

Let me see if I can crack this for the coming release.

Didn't meant to imply that asking the question was a waste of time.
Instead, I wanted to try to redirect you into coming up with solutions
to the problem instead of rehashing that this is something that could be
improved :)

I was trying to map existing HBase table to view based on the instruction:

One surprise from query on the view is all values from one column are all

the only extra parameter I am using is

Most likely to avoid breaking existing functionality.
As this mapping is a relatively new feature, we wouldn't want to force
it upon new users.
The need for Phoenix to have the proper core-site, hdfs-site, and
hbase-site XML files on the classpath is a fair knock though (although,
the lack o
is there any specific reason default value of
phoenix.schema.isNamespaceMappingEnabled set to false?
when using multiple clients like Zeppelin, DbVisualizer etc.. we need to
maintain hbase-site.xml. Particularly latest version of Zeppelin is not
recognizing hbase-site.xml, it worked only when I in
execQuery() is asynchronous and returns immediately.
next() has blocking semantics and that is why it waits for the result set
to be generated by the server side.

Client merge sort is just merging already sorted data from the parallel scan.
Look into the number of simultaneous queries vs the Phoenix thread pool size
and numActiveHandlers in Hbase region servers. Salting might not be helping
you. Also try setting the fetch size on the query in JDBC. Make s
