pgbench:tldr:cfc33
pgbench: Benchmark a database with 10 clients, 2 worker threads, and 10,000 transactions per client.
$ pgbench --client=${10} --jobs=${2} --transactions=${10000} ${database_name}

This command is using the "pgbench" tool to simulate a benchmark on a PostgreSQL database. Here is the explanation of each component of the command:
pgbench: This is the command itself, which invokes the "pgbench" tool.--client=${10}: This option specifies the number of concurrent clients (threads or processes) to use during the benchmark. It is set to a value denoted by the variable "$10" within the command. The actual value may vary depending on how the command is executed or passed arguments.--jobs=${2}: This option specifies the number of jobs (threads or processes) to use when running the benchmark. It is similar to "--client" but may represent a different aspect of parallelism. It is set to a value denoted by the variable "$2" within the command. Again, the actual value can differ based on the context in which the command is executed.--transactions=${10000}: This option sets the number of transactions or queries to be executed during the benchmark. It is set to a value denoted by the variable "$10000" within the command. The number can be adjusted to increase or decrease the workload of the benchmark.${database_name}: This is a placeholder for the name of the database on which the benchmark will be conducted. You need to substitute it with the actual name of your target database.
Overall, this command is running a "pgbench" benchmark with a specified number of concurrent clients, jobs, and transactions on a PostgreSQL database.
