  Table 1 Specifications

  No.	Specifications
  cluster1	16U64GB

Test Tool

In this test, the YCSB 0.17.0 test tool provided by the open-source community is used to connect to the GeminiDB HBase-compatible instance and fix issues in high concurrency scenarios.

For details on how to use this tool, see YCSB.

Test Metrics

Operations per Second (OPS): operations executed by a database per second

Test Procedure

1. Configure the workload file.

   Set values for fields readproportion, insertproportion, updateproportion, scanproportion, and readmodifywriteproportion in the file by referring to Table 2.

2. Use workload-insert-mostly as an example. Run the following command to prepare test data:

   nohup ./bin/ycsb load hbase -s -P workloads/workload-insert-mostly -P hbase.properties -p operationcount=400000000 -p recordcount=400000000 -threads ${thread} -p maxexecutiontime=${maxexecutiontime} -s 1> data_load.log 2>&1 &

3. Use workload-insert-mostly as an example. Run the following command to test performance:

   nohup ./bin/ycsb run hbase -s -P workloads/workload-insert-mostly -P hbase.properties -p operationcount=9000000 -p recordcount=9000000 -threads ${thread} -s 1> workload-insert-mostly_run.log 2>&1 &

Test Model

• Workload model

  Table 2 Test Model

  Test Model No.	Test Model
  workload-read (single-line read)	100% read
  workload-insert (single-line write)	100% insert
  workload-range-read (read)	100% range read

• Preset data volume

  In this performance test, 2 billion data records are preset for instances of each specification. Each data record contains 20 fields, and the size of each field is 20 bytes.
