xubo245 updated CARBONDATA-2088:
--------------------------------
Description:
It better using ‘timeseries_cube’ instead of ‘preaggregate’ for timeseries
pre-aggregate table ,because:
{code:java}
1. It is a cube that understands the dimension hierarchy of time, it is
not a simple preaggregate table
2. This datamap creates multiple pre-aggregate tables, not just one. And
DROP DATAMAP command will drop multiple table too.
{code}
and change
{code:java}
timeseries.eventTime =>eventTime
timeseries.hierarchy ＝＞hierarchy
{code}
was:
it maybe better to name it to ‘timeseries’ instead of ‘preaggregate’ for
timeseries pre-aggregate table,because:
