> Use batching when joining data table rows with uncovered local index rows
> -------------------------------------------------------------------------
>
> Key: PHOENIX-6663
> URL: https://issues.apache.org/jira/browse/PHOENIX-6663
> Project: Phoenix
> Issue Type: Improvement
> Affects Versions: 4.16.1, 5.1.2
> Reporter: Kadir OZDEMIR
> Assignee: Kadir OZDEMIR
> Priority: Major
>
> The current solution uses HBase get operations to join data table rows with
> uncovered local index rows on the server side. Issuing a separate get
> operation for every data table row can be expensive. Instead, we can buffer
> lots of data row keys in memory and use a scan with skip scan filter. This
> will reduce the cost of join and also improve the performance.
