TiDB v4.0 global variable configuration

set global tidb_hashagg_final_concurrency=1;
set global tidb_hashagg_partial_concurrency=1;

TiDB v5.0 global variable configuration

set global tidb_hashagg_final_concurrency=1;
set global tidb_hashagg_partial_concurrency=1;
set global tidb_enable_async_commit = 1;
set global tidb_enable_1pc = 1;

Test plan

1. Deploy TiDB v5.0 and v4.0 using TiUP.

2. Use BenchmarkSQL to import the TPC-C 5000 Warehouse data.

   1. Compile BenchmarkSQL:

      git clone https://github.com/pingcap/benchmarksql && cd benchmarksql && ant
      

   2. Enter the run directory, edit the props.mysql file according to the actual situation, and modify the conn, warehouses, loadWorkers, terminals, and runMins configuration items.

   3. Execute the runSQL.sh ./props.mysql sql.mysql/tableCreates.sql command.

   4. Execute the runSQL.sh ./props.mysql sql.mysql/indexCreates.sql command.

   5. Run MySQL client and execute the analyze table statement on every table.

3. Execute the runBenchmark.sh ./props.mysql command.

4. Extract the tpmC data of New Order from the result.

Test result

According to the test statistics, the TPC-C performance of TiDB v5.0 has increased by 36% compared with that of TiDB v4.0.
