---------------------------------------
Summary: Data load gets 5-7X slower with mutable sparse columns
Key: PHOENIX-3570
URL: https://issues.apache.org/jira/browse/PHOENIX-3570
Project: Phoenix
Issue Type: Sub-task
Reporter: Mujtaba Chohan
Schema with 5K columns
{noformat}
create table (k1 integer, k2 integer, column_1 varchar ... column_5000 varchar
CONSTRAINT PK PRIMARY KEY (K1, K2))
VERSIONS=1, MULTI_TENANT=true, IMMUTABLE_ROWS=FALSE
{noformat}
In this *mutable* schema, only 100 random columns are filled with random 15
chars. Rest are nulls.
Using a batch size of 1000 with single client/single thread. Time it takes to
load data is 5-7X slower compared to standard non-encoded format.
