> Simplifying concurrent mutation handling for global Indexes
> -----------------------------------------------------------
>
> Key: PHOENIX-6160
> URL: https://issues.apache.org/jira/browse/PHOENIX-6160
> Project: Phoenix
> Issue Type: Improvement
> Affects Versions: 5.0.0, 4.15.0
> Reporter: Kadir OZDEMIR
> Assignee: Kadir OZDEMIR
> Priority: Major
> Attachments: PHOENIX-6160.4.x.001.patch
>
>
> Please see the attached design document for the proposed simplification. The
> proposed design is simpler to understand and does not require a special
> handling of partial concurrent updates without indexed columns.
> One of the desired features for global indexes is to support atomic
> operations (ON_DUPLICATE_KEY statements). We have found that it is quite
> difficult to build such a feature on the current design as we need to add
> more case handling to the current design to handle data table update ordering
> issues. The proposed design does not require us to do changes on concurrent
> mutation handling for such features.
> The proposed design almost eliminates unverified index rows due to concurrent
> mutations. The index rows are left unverified only when batches fail to
> complete the data table updates. This leads to read performance improvement
> as repairing unverified rows is costly and each row repair adds several tens
> of milliseconds to the overall scan latency.
