cockroach workload as described below.
The
cockroach workload command is experimental. The interface and output are subject to change.Synopsis
Create the schema for a workload:$ cockroach workload init <workload> <flags> '<connection string'
$ cockroach workload run <workload> <flags> '<connection string'
$ cockroach workload --help
$ cockroach workload init --help
$ cockroach workload init <workload> --help
$ cockroach workload run --help
$ cockroach workload run <workload> --help
Subcommands
| Command | Usage |
|---|---|
init | Load the schema for the workload. You run this command once for a given schema. |
run | Run a workload. You can run this command multiple times from different machines to increase concurrency. See Concurrency for more details. |
Concurrency
There are two ways to increase the concurrency of a workload:- Increase the concurrency of a single workload instance by running
cockroach workload run <workload>with the--concurrencyflag set to a value higher than the default. Note that not all workloads support this flag. - Run multiple instances of a workload in parallel by running
cockroach workload run <workload>multiple times from different terminals/machines.
Workloads
| Workload | Description |
|---|---|
bank | Models a set of accounts with currency balances. For this workload, you run workload init to load the schema and then workload run to generate data. |
intro | Loads an intro database, with one table, mytable, with a hidden message. For this workload, you run only workload init to load the data. The workload run subcommand is not applicable. |
kv | Reads and writes to keys spread (by default, uniformly at random) across the cluster. For this workload, you run workload init to load the schema and then workload run to generate data. |
movr | Simulates a workload for the . For this workload, you run workload init to load the schema and then workload run to generate data. |
startrek | Loads a startrek database, with two tables, episodes and quotes. For this workload, you run only workload init to load the data. The workload run subcommand is not applicable. |
tpcc | Simulates a transaction processing workload using a rich schema of multiple tables. For this workload, you run workload init to load the schema and then workload run to generate data. |
ycsb | Simulates a high-scale key value workload, either read-heavy, write-heavy, or scan-based, with additional customizations. For this workload, you run workload init to load the schema and then workload run to generate data. |
cockroach workload sets the for its workload queries to the name of the workload that is used. You can filter queries on application_name on the , or in a statement.Flags
Thecockroach workload command does not support connection or security flags like other . Instead, you must use a at the end of the command.

Customize the frequency and format of per-operation statistics
To customize the frequency of per-operation statistics, use the--display-every flag, with ns, us, ms, s, m, and h as valid time units. To customize the format of per-operation statistics, use the --display-format flag, with incremental-json or simple (default) as options.
