Edward Capriolo commented on CASSANDRA-15082: --------------------------------------------- Why is it 5? Could it be a variable? Could it be an option when creating the table? Why or why not? It hard to a close it as a duplicate when no one is engaging with either ticket in a meaningful way. Can anyone actually use this feature without a read before write? It seems like the risk is fairly high that someone could accidentally with a forloop send the same row 5 times and hopeless corrupt the table. > SASI SPARSE mode 5 limit > ------------------------ > > Key: CASSANDRA-15082 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15082 > Project: Cassandra > Issue Type: Improvement > Components: Feature/SASI > Reporter: Edward Capriolo > Priority: Normal > > I do not know what the "improvement" should be here, but I ran into this: > [https://github.com/apache/cassandra/blob/cassandra-3.11/src/java/org/apache/cassandra/index/sasi/disk/OnDiskIndexBuilder.java#L585] > Term '55.3' belongs to more than 5 keys in sparse mode, which is not allowed. > The only reference I can find to the limit is here: > [http://www.doanduyhai.com/blog/?p=2058] > Why is it 5?
