+# TiDB TPC-H 100GB Performance Test Report -- TiDB v5.0 MPP mode vs. Greenplum 6.15.0 and Apache Spark 3.1.1
+
+## Test overview
+
+This test aims at comparing the TPC-H 100GB performance of TiDB v5.0 in the MPP mode with that of Greenplum and Apache Spark, two mainstream analytics engines, in their latest versions. The test result shows that the performance of TiDB v5.0 in the MPP mode is two to three times faster than that of the other two solutions under TPC-H workload.
+
+In v5.0, TiDB introduces the MPP mode for [TiFlash](/tiflash/tiflash-overview.md), which significantly enhances TiDB's Hybrid Transactional and Analytical Processing (HTAP) capabilities. Test objects in this report are as follows:
+
++ TiDB v5.0 columnar storage in the MPP mode
++ Greenplum 6.15.0
++ Apache Spark 3.1.1 + Parquet
+
+## Test environment
+
+### Hardware prerequisite
+
++ Node count: 3
++ CPU: Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz, 40 cores
++ Memory: 189 GB
++ Disks: NVMe 3TB * 2
+
+### Software version
+
+| Service type   | Software version   |
+|:----------|:-----------|
+| TiDB      | 5.0        |
+| Greenplum   |  6.15.0  |
+| Apache Spark | 3.1.1   |
+
+### Parameter configuration
+
+#### TiDB v5.0
+
+For the v5.0 cluster, TiDB uses the default parameter configuration except for the following configuration items.
+
+In the configuration file `users.toml` of TiFlash, configure `max_memory_usage` as follows:
+
+```toml
+[profiles.default]
+max_memory_usage = 10000000000000
+```
+
+Set session variables with the following SQL statements:
+
+```sql
+set @@tidb_isolation_read_engines='tiflash';
+set @@tidb_allow_mpp=1;
+set @@tidb_opt_broadcast_join=0;
+set @@tidb_mem_quota_query = 10 << 30;
+```
+
+All TPC-H test tables are replicated to TiFlash in columnar format, with no additional partitions or indexes.
+
+#### Greenplum
+
+Except for the initial 3 nodes, the Greenplum cluster is deployed using an additional master node. Each segment server contains 8 segments, which means 4 segments per NVMe SSD. So there are 24 segments in total. The storage format is append-only/column-oriented storage and partition keys are used as primary keys.
+
+{{< copyable "" >}}
+
+```
+log_statement = all
+gp_autostats_mode = none
+statement_mem = 2048MB
+gp_vmem_protect_limit = 16384
+```
+
+#### Apache Spark
+
+The test of Apache Spark uses Apache Parquet as the storage format and stores the data on HDFS. The HDFS system consists of three nodes. Each node has two assigned NVMe SSD disks as the data disks. The Spark cluster is deployed in standalone mode, using NVMe SSD disks as the local directory of `spark.local.dir` to speed up the shuffle spill, with no additional partitions or indexes.
