- Specifies the size of the default pool. Operator instances that do not specify a placement : host config or do not have an implied host placement are placed to a host from the default pool. The default pool is assumed to be unsized, untagged, and shared when a size is not specified through the defaultPoolSize config. It is assumed to be sized if a defaultPoolSize config is present, or the -d, --default-pool-size option to the compiler is used to specify a size. The config takes precedence over the compiler option.
