Go 1.19: GOMEMLIMIT prevents GC-related OOM kills

AI Impact Summary

Go 1.19 introduced GOMEMLIMIT, a critical feature that allows developers to explicitly limit memory usage for Go applications. Previously, Go's garbage collector operated on a relative target, making it difficult to prevent out-of-memory (OOM) errors, especially for applications with persistent heap allocations. GOMEMLIMIT provides a hard limit, preventing the heap from exceeding the specified size and mitigating the risk of GC-related OOM kills, as demonstrated in the Weaviate example.
