rpk redpanda mode

This command is not supported on macOS, Windows.

Development mode

Development mode (development or dev) includes the following development-only settings:

  • Sets developer_mode to true. This starts Redpanda with dev-mode only settings, including:

    • No minimal memory limits are enforced.

    • No core assignment rules for Redpanda nodes are enforced.

    • Bypasses fsync (from Seastar option unsafe_bypass_fsync), which results in unrealistically fast clusters and may result in data loss.

  • Sets overprovisioned to true. Redpanda expects a dev system to be an overprovisioned environment. Based on a Seastar option, setting overprovisioned disables thread affinity, zeros idle polling time, and disables busy-poll for disk I/O.

  • Sets all autotuner tuners to false. The tuners are intended to run only for production mode.

Production mode

Production mode (production or prod) disables dev-mode settings:

  • developer_mode: false

  • overprovisioned: false

It also enables a set of tuners of the autotuner. For descriptions about the tuners, see Tuners in the rpk redpanda tune list command reference.

Recovery mode

Recovery mode (recovery) sets the broker configuration property recovery_mode_enabled to true. This provides a stable environment for troubleshooting and restoring a failed cluster.
