--------------------------------------
Summary: 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: 5.1.2, 4.16.1
Reporter: Kadir OZDEMIR
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.
