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
