--------------------------------------------
Summary: cassandra-stress in user profile mode fails on handling
set<set<int>> columns
Key: CASSANDRA-15598
URL: https://issues.apache.org/jira/browse/CASSANDRA-15598
Project: Cassandra
Issue Type: Bug
Reporter: Dmitry Kropachev
Reason:
c-s reads metadata from database, and build column generator from it.
But this logic is build in a way so that it does not support generator
recursion, which is necessary to support embedded collections.
Fix:
This fix is simple exclude this type of columns from being generated.
Steps to reproduce:
# docker run -d --name cassandra cassandra:latest
# cassandra-stress user profile=cs_no_mv_basic_profile.yaml ops'(insert=1)'
cl=ONE n=20 -pop seq=1..10000000 -port jmx=6868 -mode cql3 native -rate
threads=2 -node 172.17.0.2
# docker exec -ti cassandra cqlsh -e 'ALTER TABLE mview.users ADD ( asdasdasd
set<frozen<set>>);'
# cassandra-stress user profile=cs_no_mv_basic_profile.yaml ops'(insert=1)'
cl=ONE n=20 -pop seq=1..10000000 -port jmx=6868 -mode cql3 native -rate
threads=2 -node 172.17.0.2
