Subject Frequent updates of freshly written columns
Date Fri, 18 Feb 2011 07:14:34 GMT
Are the very freshly written columns to a row in memtables, efficiently
updated/overwritten by edited/new column values.

After flushing of memtable, are those(edited + unedited ones) columns stored
together on disk (in same blocks!?) as if they were written in one single
operation or same time ?? I know if old columns are edited then several
copies of same column will be dispersed in different sst tables, what about
fresh columns ?

Are there any disadvantages to frequently updating fresh columns present in
memtable ?
