-------------------------------------------
Summary: SASI SPARSE mode 5 limit
Key: CASSANDRA-15082
URL: https://issues.apache.org/jira/browse/CASSANDRA-15082
Project: Cassandra
Issue Type: Improvement
Reporter: Edward Capriolo
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 usercan insert more then 5 rows into a table, and it
"works". IE you can write an you can query, but the index will not flush to
disk. It throws an IOException. I
Maybe I am misunderstanding, but this seems impossible to support, if users
insert the same value 5 times, the entire index will not flush to disk?
