Review Comment:
Maybe something like this:
```suggestion
config(schema, mode, length, cols);
private MetricsConfig config(Schema schema, MetricsMode mode, int
length, String[] cols) {
TestTables.TestTable table =
TestTables.create(
tableDir,
"test",
schema,
PartitionSpec.unpartitioned(),
3,
[..]
);
return MetricsConfig.forTable(table);
}
```
