Hi Experts, We have tables (a.k.a. column family) A and B. The row of the table is simply a key value pair. Table A and B are written by clients all the time. We need to transform the row key of table A and B according to a set of rules, join these two tables and save the results to table C for read.
Questions 1) Schema like this is very close to a schema in SQL. We mainly want to separate read and write operations by different column families. Is this a correct way to model the join in Cassandra? 2) If the rules change a little bit, which is quite possible, we will have to drop table C, and recompute the join result, which seems to be cumbersome because not all the join results need to be changed, just some of them. Are there any better ways to handle such change? Thanks a lot. -- Regards, Jiaan
