Multiple nodes could be a problem but multiple threads is probably just fine. If you have two threads write to the same column, the last one wins though so I hope your timestamps are unique even across threads so you don't lose data ;).

In the situation, there are multiple client thread updating or adding new columns in a same row. These new columns is a time series data. My Question is - Would multiple threads able to add columns to the same row? Do you see any performance issues since there is a comparator and has to sort columns as they get added. Do you see any loss of data or conflict due to mulitple thread updating data? I am expecting high volumn of data coming on each one of those threads. Thanks in advance. Jay
