In this condition, I find the write speed it almost the same;In this case,can I use B to replace A,because table B can not add column.I just want to get the confirm of authority.
Which CarbonData version you used?
You can use command 'ALTER TABLE carbon ADD COLUMNS (a1 INT, b1 STRING)' to
add columns for non-streaming table.
BTW, you can add my weixin: xm_zzc to discuss with me.
