GOMEMLIMIT
With GOMEMLIMIT, you set a soft cap on the memory usage of the Go runtime, encompassing the heap and other runtime-managed memory. This cap is like telling your application, “Here’s your memory budget; spend it wisely.”
Since Go 1.20, the strategic focus has shifted from manual tweaks such as memory ballast to leveraging built-in runtime features for memory management. GOMEMLIMIT offers a more straightforward and manageable approach to limiting memory usage.
The GOMEMLIMIT variable is used to set a soft memory limit for the runtime. This limit encompasses the Go heap and all other memory managed by the runtime, but it doesn’t include external memory sources such as mappings of the binary, memory managed in other languages, or memory held by the operating system on behalf of the Go program. GOMEMLIMIT is a numeric value measured in bytes, with the option to add a unit suffix for clarity. The supported suffixes include B, KiB, MiB, GiB, and...
