---------------------------------------
Summary: Enable compression for immutable encoded table
Key: PHOENIX-3638
URL: https://issues.apache.org/jira/browse/PHOENIX-3638
Project: Phoenix
Issue Type: Sub-task
Reporter: Mujtaba Chohan
Assignee: Samarth Jain
Immutable column encoding with offset data is highly compressible, in test with
various schemas, space saving ranges from 1.5X to 3X whereas FAST_DIFF encoding
has not any significant impact as expected.
Enabling compression would lead to better performance for disk I/O bound
queries. The amount of space saving depends on sparsity, number of columns and
data shape.
