Subject row caching for frequently updated column
Date Tue, 29 Apr 2014 02:27:32 GMT
I am wondering if there is any negative impact on Cassandra write
operation, if I turn on row caching for a table that has mostly 'static
columns' but few frequently write columns (like timestamp).

The application will frequently write to a few columns, and the application
will also frequently query entire row.

How Cassandra handle update column to a cached row?
does it update both memtables value and also the row cached row's
column(which dealing with memory update so it is very fast) ?
or in order to update the cached row, entire row need to read back from
sstable?


thanks
