Subject [jira] [Commented] (CARBONDATA-745) Does carbondata apply to scenes that need to sort historical and current data?
Date Tue, 07 Mar 2017 11:50:37 GMT

    [ https://issues.apache.org/jira/browse/CARBONDATA-745?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15899315#comment-15899315

Liang Chen commented on CARBONDATA-745:
---------------------------------------

First,  see if i understood it:
There is a sorted table, and will generate a new table with real-time data. the two tables
have one same column(eg: name is key), you want to do join by column "key" to merge two tables
into one table,  complete sort operation along with joining operation , is it correct ?

During loading data, can't do like that. For two different table data, you must manually do
join operation as per your requires.

Regards
Liang

> Does carbondata apply to scenes that need to sort historical and current data?
> Now there is a new scene that needs to sort the current data and historical data in real
time according to certain rules,and returns the sorted data when querying.
> It's just like hbase put data sorted by rowkey.
> We want to sort the data when we load the data without having to spend extra time to
sort。
> Is it suitable for this scene?
