Benchmarks are run by the github-workflow docker integration-test, eg here
- All benchmark codes could be seen in the test code directory, you can do the bench on your machine too.
- Both
Clickhouse-Native-JDBCandclickhouse-jdbcare good jdbc clients. Andclickhouse-jdbcare maintained better, this benchmarks only show your some difference, users could choose freely according to their needs. - The result's score means the avg_time to process one operation, lower is better.
- With string type of JDBC batch insertion,
Clickhouse-Native-JDBCandclickhouse-jdbcare almost the similar performance. - With other types of JDBC batch insertion or selection,
Clickhouse-Native-JDBCmay be 1~4 times better thanclickhouse-jdbc. clickhouse-jdbcRowBinary insert performs similar performance vsClickhouse-Native-JDBC, it's not jdbc standared yet it's pretty efficient for the client because it sends data by row stream rather than one big block, but it's not columnar based and may cause the clickhouse-server CPU higher load (On my machine, this's maybe 3 times overload by loop benchmark).- Here are the benchmark Params:
batchSize: insert batch size.columnNum: insert column number, used in the WideColumn/RowBinary benchmarks.selectNumber: select row size.
