Hi Vikram,
This question comes up somewhat often, so I'd be very interested in
comments from other users of Solr and Phoenix as well.
You'd need to either pre-parse fields from XML and save them as column
values to use in queries, or use a UDF to dynamically parse XML stored
within a single
No, it's currently not possible to have a secondary index on dynamic
columns. You can, however, create a view with new, ad hoc columns and add a
secondary index on the view.

Hi,
Is there a way to make phoenix build indexes on secondary columns?

Thanks for the clarifications, Nick. That's a cool idea for cube building -
I'm not aware of any JIRAs for that.
FYI, for approximate count, we have PHOENIX-418 which Ravi is working on. I
think he was looking at using a HyperLogLog library, but perhaps BlinkDB is
an alternative.

Hi,
How to map the HBase column qualifier which is in byte type(highlighted
below) to the view in phoenix?
eg.,
\x00\x00\x00\x0Bcolumn=fact:\x05, timestamp=1460666736042,
value=\x02\x9E.\x8A
Please help.

The stats table would purely be used to drive optimizer decisions in
Phoenix. The data in the table is only collected during major compaction
(or when an update stats is run manually), so it's not really meant for
satisfying queries.
For Kylin integration, we'd rely on Kylin to maintain the cubes
FYI, Lars H. is looking at PHOENIX-258 for improving performance of
DISTINCT. We don't yet keep any cardinality info in our stats
(see PHOENIX-1178).
Thanks,

Hello,
I'm curious if there are any tricks for estimating the cardinality of the
values in a phoenix column. Even for leading rowkey column, a select
distinct query on a large table requires a full scan (PHOENIX-258). Maybe
one could reach into the stats table and derive some knowledge? How much
Hi,
Are there any use cases ,resources or experience substitutingsolr with

I found it much easier and reliable to make my own phoenix HTTP server with
my own JSON API. It was too confusing for me to send multiple requests for
what would normally be just one SQL statement. And I had problems getting
upserts working, to boot (even with the thin server). Now I can make
Hey folks,
I'm trying to UPSERT some data via the json api but no luck for now. My
requests looks like:
{
"request": "openConnection",
"connectionId": "6"
}
{
"request": "createStatement",
"connectionId": "6"
}
{

Hi guys As I know create table a like b syntax should have been supported
since long before(refer to https://issues.apache.org/jira/browse/PHOENIX-734)
,however when i am using phoenix 4.5, i got below exception:0:
jdbc:phoenix:cnzk0,cnzk1,cnzk2> create table debug_visit like visit;Error:
Now another error appears for prepare and execute batch request:
content="text/html;charset=ISO-8859-1"/>
Error 500
HTTP ERROR: 500
Problem accessing /. Reason:
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException:
Ah i found the error. It should be "sqlCommands": instead of "sqlCommands",
The documentation syntax is wrong for this request type:

Folks,
I'm trying to prepare and execute batch request with no luck.
These are the requests i send:

}
{
"request": "prepareAndExecuteBatch",
