question Re: kudu is slower than parquet? in Support Questions https://community.cloudera.com/t5/Support-Questions/kudu-is-slower-than-parquet/m-p/56648#M14070 Impala heavily relies on parallelism for throughput so if you have 60 partitions for Kudu and 1800 partitions for Parquet then due to Impala's current single-thread-per-partition limitation you have built in a huge disadvantage for Kudu in this comparison. Please let us know if you re-run your comparison test.
