[jira] [Updated] (PHOENIX-6219) GlobalIndexChecker should work for index:SINGLE_CELL_ARRAY_WITH_OFFSETS and data:ONE_CELL_PER_COLUMN

["Gokcen Iskender (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PHOENIX-6219?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gokcen Iskender updated PHOENIX-6219:
-------------------------------------
    Description: GlobalIndexChecker has repairIndexRows method, that builds a scan for data table and goes over indexMaintainer.getAllColumns to get columns from that. But the issue is there are only 2 columns for the SINGLE_CELL index. That part needs to change.  (was: This Jira is a followup Jira of PHOENIX-5923 where data and index might have different storage and encoding formats. IndexMaintainer and protobuf needs to change to handle this. Right now, index maintainer assumes both index and data tables have the same format. The protobuf needs to be changed so that IndexMaintainer knows about the data table storage and encoding formats

Repro:
 # Create a table with ONE_CELL_PER_COLUMN storage format
 # Create an index that has covered columns and the IMMUTABLE_STORAGE_SCHEME is SINGLE_CELL_ARRAY_WITH_OFFSETS
 # Upsert rows to data table
 # Query the covered column using index --> Null value is returned even though there is a value. 

IndexMaintainer has a 4 year old code that doesn't return a value for covered columns,)
