---------------------------------------------
Just ran the branch through some Harry fuzz testing w/ the {{bti}} format
active. The configuration I'm using basically looks like this:
{noformat}
new Configuration.ConfigurationBuilder()
.setSeed(1L)
.setSchemaProvider(new
Configuration.DefaultSchemaProviderConfiguration())
.setDropSchema(false)
.setCreateSchema(true)
.setTruncateTable(false)
.setClock(new
Configuration.ApproximateMonotonicClockConfiguration(7300, 1, TimeUnit.SECONDS))
.setSUT(new InJvmSutConfiguration(3, 10, ...))
.setPartitionDescriptorSelector(new
Configuration.DefaultPDSelectorConfiguration(10, 100))
.setClusteringDescriptorSelector(
new Configuration.DefaultCDSelectorConfiguration(
new Configuration.ConstantDistributionConfig(4),
new Configuration.ConstantDistributionConfig(2),
1000,
ImmutableMap.<OpSelectors.OperationKind,
Integer>builder()
.put(OpSelectors.OperationKind.DELETE_RANGE, 1)
.put(OpSelectors.OperationKind.DELETE_SLICE, 1)
.put(OpSelectors.OperationKind.DELETE_ROW, 1)
.put(OpSelectors.OperationKind.DELETE_COLUMN, 1)
.put(OpSelectors.OperationKind.DELETE_PARTITION, 1)
.put(OpSelectors.OperationKind.DELETE_COLUMN_WITH_STATICS, 1)
.put(OpSelectors.OperationKind.INSERT_WITH_STATICS, 50)
.put(OpSelectors.OperationKind.INSERT,
50)
.put(OpSelectors.OperationKind.UPDATE_WITH_STATICS, 50)
.put(OpSelectors.OperationKind.UPDATE,
50)
.build(),
null))
.setRunner(new
Configuration.SequentialRunnerConfig(ImmutableList.of(
new

.build();
{noformat}
I managed to get through that hour run without detecting any problems, which is
a good sign. Going to press on and finish the actual review...
