---------------------------
Summary: UTF-8 column name support
Key: KYLIN-5255
URL: https://issues.apache.org/jira/browse/KYLIN-5255
Project: Kylin
Issue Type: Wish
Affects Versions: v4.0.1
Reporter: Lilo
Perhaps it's an appropriate time to support UTF-8 column names? (Kylin4 using
Spark to build Cube)
Although the Hive documentation still says that UTF-8 characters are not
supported for table or column names, but after some simple sql tweaks to hive
metadata, we had no problems using UTF-8 column names in production (e.g. in
Hive / Spark2 / Spark3 / Impala / Presto / Flink).
(Tweaks like
{code:sql}
alter table COLUMNS_V2 modify column COLUMN_NAME varchar(255) character set
utf8;{code}
)
