--------------------------------------------
Summary: Allow column name mapping for few/all columns in
underlying storage tables
Key: LENS-710
URL: https://issues.apache.org/jira/browse/LENS-710
Project: Apache Lens
Issue Type: Improvement
Components: driver-jdbc
Reporter: Amareshwari Sriramadasu
This improvement proposed is to accept column mapping for few or all columns in
underlying storage tables - which allows column to be different in underlying
storage than column in fact/dimtable
For example:
Fact1 has col1
S1_Fact1 has col1
S2_Fact2 has col1_variant
S2_Fact2 can have column mapping property specified as col1:col1_variant. If
S2_Fact2 becomes the eligible storage table, then query should be written with
col1_variant if col1 is queried.
