maxExecutionEnvironments?

Type: number (optional, default: No maximum specified)

The maximum number of execution environments allowed for the $LATEST.PUBLISHED version when published into a capacity provider.

This setting limits the total number of execution environments that can be created to handle concurrent invocations of this specific version.

---

minExecutionEnvironments?

Type: number (optional, default: 3 execution environments are set to be the minimum)

The minimum number of execution environments to maintain for the $LATEST.PUBLISHED version when published into a capacity provider.

This setting ensures that at least this many execution environments are always available to handle function invocations for this specific version, reducing cold start latency.
