JDBC driver

This JDBC driver leverages Hikari Connection Pool for connection pool and works with PostgreSQL®. This leverages NoSQLBench based workload generation and performance testing against any PostgreSQL-compatible database cluster. Example: CockroachDB® or YugabyteDB® (YSQL API).

Executing JDBC Workload

The following is an example of invoking a JDBC workload.

<nb_cmd> run driver=jdbc workload="/path/to/workload.yaml" cycles=1000 threads=100 url="jdbc:postgresql://" serverName=localhost portNumber=5432 databaseName=defaultdb ... -vv --show-stacktraces

In the above NB command, following are JDBC driver specific parameters:

Other NB engine parameters are straight forward:


These are the main configurations with which we could issue a query and process the results back based on the PostgreSQL® Query pattern.

Statement Forms

The syntax for specifying these types is simplified as well, using only a single type field which allows values of execute, query, & update and specifying the raw statements in the stmt. Alternatively, one could directly use one of the types and provide the raw query directly.

Op Template Examples

    type: execute
    stmt: |
      DROP DATABASE IF EXISTS TEMPLATE(database,baselines);
    execute: |
      CREATE TABLE IF NOT EXISTS TEMPLATE(database,baselines).TEMPLATE(table,keyvalue);
    query: |
      SELECT one, two, three FROM TEMPLATE(database,baselines).TEMPLATE(table,keyvalue) WHERE ...;
    update: |
      UPDATE TABLE TEMPLATE(database,baselines).TEMPLATE(table,keyvalue) SET key = 'value' WHERE ...;
