Philip Thompson commented on CASSANDRA-10657:
---------------------------------------------
This broke alter_rf_and_run_read_repair_test, the test for CASSANDRA-10655. As
this is a follow-up to 10655, is the new behavior expected?
Failure is
[here|http://cassci.datastax.com/job/trunk_dtest/940/testReport/read_repair_test/TestReadRepair/alter_rf_and_run_read_repair_test/]
Potentially [now] invalid assumption from test
{code}
# Alter so RF=n but don't repair, then execute a query which selects only a
subset of the columns. Run this at
# CL ALL on one of the nodes which doesn't currently have the data,
triggering a read repair. Although we're
# only selecting a single column, the expectation is that the entire
row is read on each replica to construct
# the digest responses as well as the full data reads for repair. So we
expect that after the read repair, all
# replicas will have the entire row

> This is a followup to CASSANDRA-10655, to re-enable the optimization of
> skipping values for the columns that are not requested by users in a CQL
> query. See CASSANDRA-10655 for why it was disabled, the goal here is to
> re-enable it minus the bugs.
