TPC-H Benchmark

TPC-H is a decision support benchmark developed by the Transaction Processing Performance Council (TPC). It consists of a suite of business oriented ad-hoc queries and concurrent data modifications. TPC-H can be used to build models based on real production environments to simulate the data warehouse of a sales system. This test uses eight tables with a data size ranging from 1 GB to 3 TB. A total of 22 queries are tested and the main performance metrics are the response time of each query, which is the duration between the time a query is submitted to the time the result is returned.

1. Test conclusion

A comparative test was conducted on the TPC-H 100G scale dataset, with a total of 22 queries. The results are as follows:

TPCH 100G results

StarRocks tested two methods using local storage and Hive table queries. StarRocks Hive table and Trino query the same data. The data is stored in ORC format and compressed in zlib format.

The latency for StarRocks to query data from its native storage is 21s, that for StarRocks to query Hive external tables is 92s, and that for Trino to query Hive external tables was 187s.

4. Test process

4.1 Query StarRocks Native Table

4.1.1 Generate data

Download the tpch-poc tool package to generate data for the TPC-H standard test set scale factor=100.

wget https://starrocks-public.oss-cn-zhangjiakou.aliyuncs.com/tpch-poc-1.0.zip
unzip tpch-poc-1.0
cd tpch-poc-1.0

sh bin/gen_data/gen-tpch.sh 100 data_100

4.1.2 Create table structure

Modify the configuration file conf/starrocks.conf, specify the cluster address (host and port), and then perform the table creation operation.

sh bin/create_db_table.sh ddl_100

4.1.3 Import data

sh bin/stream_load.sh data_100

4.1.4 Query data

sh bin/benchmark.sh

4.2 Query Hive external tables with StarRocks

4.2.1 Create table structure

Create an external table in Hive. The external table storage format is ORC and the compression format is zlib. For detailed table creation statements, see 5.3. This Hive external table is used for both StarRocks and Trino queries.

http://localhost:3000/docs/benchmarking/TPC-H_Benchmarking/

4.2.2 Import data

Upload the TPC-H CSV original data generated in step 4.1.1 to the HDFS specified path (this article uses the path /user/tmp/csv/), and then create an external table in Hive. For detailed table creation statements, see 5.4. The storage format of this Hive external table is CSV, and the storage path is /user/tmp/csv/, the path where the CSV original data is uploaded.

Import the data of the external table in CSV format into the external table in ORC format using INSERT INTO, so that the data is obtained in the storage format of ORC and the compression format of zlib. The import command is as follows:

use tpch_hive_csv;

insert into tpch_hive_orc.customer select * from customer;
insert into tpch_hive_orc.lineitem select * from lineitem;
insert into tpch_hive_orc.nation select * from nation;
insert into tpch_hive_orc.orders select * from orders;
insert into tpch_hive_orc.part select * from part;
insert into tpch_hive_orc.partsupp select * from partsupp;
insert into tpch_hive_orc.region select * from region;
insert into tpch_hive_orc.supplier select * from supplier;

4.2.3 Query data

StarRocks uses the Catalog function to query Hive table data. For detailed operations, see Hive catalog.
