-----------------------------------
Summary: Stress should validate the results of queries in "user"
profile mode
Key: CASSANDRA-8431
URL: https://issues.apache.org/jira/browse/CASSANDRA-8431
Project: Cassandra
Issue Type: Improvement
Components: Tools
Reporter: Benedict
CASSANDRA-8429 was exhibited by the validation logic in stress. However at the
moment the new-fangled profile driven "user" mode doesn't perform any
validation. So as we default more and more to the new approach we will be less
and less likely to spot correctness issues.
Introducing validation logic here could be tricky, since we can support
arbitrary user queries. However we could support a query mode where only the
columns and number of cql rows to fetch are defined, for which we could
calculate the exact result set we expect. There would be complications with
insertions that proceed out-of-order, but we could either not support this
mode, or have a validation mode that just ensures a superset of the data we
know to be inserted has been.
