Since `GetExperiments` traverses the proto structure and allocates a new slice on every call, this introduces unnecessary overhead. Consider caching the experiments list or the result of the integrity check (e.g., in the context or a local variable) since pipeline options do not change during the boot process. ########## sdks/go/pkg/beam/artifact/options.go: ########## @@ -0,0 +1,69 @@ +// Licensed to the Apache Software Foundation (ASF) under one or more +// contributor license agreements.

It is safer to collect and combine experiments from both locations. Additionally, using explicit checks improves readability over the long chain of calls. ```go if optVal, ok := options.GetFields()["options"]; ok { if experimentsVal, ok := optVal.GetStructValue().GetFields()["experiments"]; ok { for _, v := range experimentsVal.GetListValue().GetValues() { exps = append(exps, v.GetStringValue()) } } } // Try URN style if urnVal, ok := options.GetFields()["beam:option:experiments:v1"]; ok { for _, v := range urnVal.GetListValue().GetValues() { exps = append(exps, v.GetStringValue()) } } return exps ``` ########## sdks/go/pkg/beam/artifact/materialize.go: ########## @@ -231,7 +233,18 @@ func (a artifact) retrieve(ctx context.Context, dest string) error { stat, _ := fd.Stat() log.Printf("Downloaded: %v (sha256: %v, size: %v)", filename, sha256Hash, stat.Size()) - return fd.Close() + if err := fd.Close(); err != nil { + return err + } + + if isArtifactValidationEnabled(ctx) { + if a.expectedSha256 != "" && sha256Hash != a.expectedSha256 { + return errors.Errorf("bad SHA256 for %v: %v, want %v", filename, sha256Hash, a.expectedSha256) + } + log.Printf("Sha256 validation done for file: %v, with sha256 %v", filename, a.expectedSha256) Review Comment:  Logging a success message for every artifact validation can be very noisy for jobs with a large number of staged files. Consider removing this log or reducing its verbosity level, as it provides little value during normal successful operation. -- This is an automated message from the Apache Git Service.
