--------------------------------------
Summary: Using global indexes for queries with uncovered columns
Key: PHOENIX-6458
URL: https://issues.apache.org/jira/browse/PHOENIX-6458
Project: Phoenix
Issue Type: Improvement
Affects Versions: 5.1.0
Reporter: Kadir Ozdemir
Phoenix client does not use a global index for the queries with the columns
that are not covered by the global index. However, there are many cases where
using the global index to map secondary keys to primary keys and then
retrieving the corresponding rows from the data table results in faster
queries. It is expected that such performance improvement will happen when the
index row key prefix length is greater than the data row key prefix length for
a given query.
