> Key: PHOENIX-5736
> URL: https://issues.apache.org/jira/browse/PHOENIX-5736
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 5.0.0
> Reporter: Kadir OZDEMIR
> Priority: Critical
> Attachments: skipScanTest.txt

> 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.
