The eight tables contain 1 SF of data in total, excluding the space occupied by indexes. To generate the update files needed for a 4 stream run of the throughput test at GB, using an existing set of seed files from an 8 process load: dbgen -s -U 4 -C 8 7. TPC-H Vesion 2 and Version 3 Over the past few years the industry has seen increases in performance and decreases in costs of computer and database systems. The total file size is about GB and may need a few minutes to an hour to generate. Packages 0 No packages published. If nothing happens, download Xcode and try again. These aspects include the selected database size against which the queries are executed, the query processing power when queries are submitted by a single stream, and the query throughput when queries are submitted by multiple concurrent users. How is QGEN built?❿

The queries and the data populating the database have been chosen to have broad industry-wide relevance. This benchmark illustrates decision support systems that examine large volumes of data, execute queries with a high degree of complexity, and give answers to critical business questions.

These aspects include the selected database size against which the queries are executed, the query processing power when queries are submitted by a single stream, and the query throughput when queries are submitted by multiple concurrent users. Execute the following statements to import the nation and region tables to the database:. Upload the other six tables to the OSS bucket by using ossutil. For more information about how to use ossutil, see Overview.

Therefore, the OSS bucket is required to import the tables. Execute the following statements to upload the tbl files of the six tables to the OSS bucket by using ossutil:. You can execute a Shell script to start the test or use a client tool such as psql to individually execute SQL queries. This section describes the two methods. Create a Shell script named query. The Shell script contains the following content.

It is used to perform queries and record the execution time of each query and the total execution time of all queries. Run the query. Document Center. All Products. Note The ECS instance must be attached with a database. Here we use Apache Doris 1. In the test, we use Query Time ms as the main performance indicator. The test results are as follows:. Execute the following script to download and compile the tpch-tools tool.

The total file size is about GB and may need a few minutes to an hour to generate. Or copy the table creation statement in create-tpch-tables. Execute the following SQL statement to check that the imported data is consistent with the above data. At present, the query optimizer and statistics functions of Doris are not so perfect, so we rewrite some queries in TPC-H to adapt to the execution framework of Doris, but it does not affect the correctness of the results.

Skip to main content. This is unreleased documentation for Apache Doris 1.
