Kylin didn't support window function yet. Here's a test query:
{code}
select lstg_format_name, count(*) over(partition by lstg_format_name)
from kylin_sales
{code}
The query threw a exception and here's the error log and stack trace:
{code}
Error while executing SQL "select lstg_format_name, count(*) over(partition by lstg_format_name) from kylin_sales LIMIT 50000": cannot translate call COUNT() OVER (PARTITION BY $t3 RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)
{code}
{code}
Caused by: java.lang.RuntimeException: cannot translate call COUNT() OVER (PARTITION BY $t3 RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)
