Edward Capriolo updated CASSANDRA-15082:
----------------------------------------
Description:
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? Could it be a variable? Could it be an option when creating the
table? Why or why not?
This seems awkward. A user can insert more then 5 rows into a table, and it
"works". IE you can write and you can query that table getting more than 5
results, but the index will not flush to disk. It throws an IOException.
Maybe I am misunderstanding, but this seems impossible to support, if users
inserts the same value 5 times, the entire index will not flush to disk?
