Hi I have a question about the internal of cassandra write. Say, I already have the following in the database - (row_x,col_y,val1)
Now if I try to insert (row_x,col_y,val100), what will happen? Will it overwrite the old data? I mean, will it overwrite the data physically or will it keep both the old version and the new version of the data? If the later is the case, can I retrieve the old version of the data? One sample example where I may need this is as follows - say I want to log the stock price of a particular company over time. Say company name is the row key and stock price is the column. Then the stock price column needs to be written repeatedly. HTH thanks Maifi
