Subject [jira] [Updated] (CARBONDATA-2088) It better using ‘timeseries_cube’ instead of ‘preaggregate’ for timeseries pre-aggregate table
Date Fri, 26 Jan 2018 09:50:00 GMT

     [ https://issues.apache.org/jira/browse/CARBONDATA-2088?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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: 

{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}
