Re: Query on mapping Hbase table with Phoenix where rowkey is composite of multiple columns
Getting issue while creating Phoenix View for my scenario. CREATE view IF NOT EXISTS Test ( 0.CustomerName VARCHAR, 0.LocationName VARCHAR, 0.ReferringPhysicianKey VARCHAR, 0.ExamKey VARCHAR CONSTRAINT PK PRIMARY KEY (CustomerName,LocationName,ExamKey) ); Getting Error as below. Primary key columns must not have a family name. columnName=Test.0.CUSTOMERNAME (state=42J01,code=1003) What should be best way to create phoenix table/view mapping my hbase table. My hbase rowkey is combination of 3 columns. In my SQL first 2 columns always exists in where clause. Thanks in advance.

Yes. Currently I have used | as seperator. I think phoenix does not support to use custom seperator. I am planning to use one byte as seperator which phoenix use when you load through phoenix. All the variables are variable length and they are strings.
