--------------------------------------
Summary: Mutable global index rebuilds are incorrect after
PHOENIX-5494
Key: PHOENIX-5736
URL: https://issues.apache.org/jira/browse/PHOENIX-5736
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.14.3, 5.0.0, 4.15.0
Reporter: Kadir OZDEMIR
PHOENIX-5494 uses skip scans to improve write performance for tables with
indexes. Before this jira, a separate scanner was opened for each data table
mutation to read all versions and delete markers of for the row to be mutated.
With this jira, a single scanner is opened using a raw scan with a skip scan
filter to read all versions and delete markers of the all rows in a batch.
Reading existing data table rows is required to generate index updates.
However, I have discovered that a raw scan with a skip scan filter does not
return all raw versions. This means that after PHOENIX-5494 index rebuilds for
global indexes will not be correct.
