# Object Lock and Immutability Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

MinIO server allows WORM for specific objects or by configuring a bucket with default object lock configuration that applies default retention mode and retention duration to all objects. This makes objects in the bucket immutable i.e. delete of the version are not allowed until an expiry specified in the bucket's object lock configuration or object retention.

        return Objects.equals(groupId, that.groupId)
                && Objects.equals(artifactId, that.artifactId)
                && Objects.equals(type, that.type)
                && Objects.equals(classifier, that.classifier)
                && Objects.equals(version, that.version);
    }

    @Override
    public int hashCode() {
        return Objects.hash(groupId, artifactId, type, classifier, version);

-kv | output inner key value pairs as newly formed objects
-v | output depth and offset details for each value
-h | display help dialog

## Benchmarks

Obligatory benchmarks performed on files with arrays of objects, where the decoded objects are to be extracted.

Two file sizes are used -- regular (1.6mb, 1000 objects) and large (128mb, 100000 objects)

input size | lib | MB/s | Allocated
--- | --- | --- | ---

    public Task(String value) {
        this.value = Objects.requireNonNull(value, "value");
    }

    public String getValue() {
        return value;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) {
            return true;
        }
        if (o instanceof Task task) {
            return Objects.equals(getClass(), task.getClass()) && Objects.equals(value, task.value);
        } else {

        }

        return Objects.equals(a1.getGroupId(), a2.getGroupId())
                && Objects.equals(a1.getArtifactId(), a2.getArtifactId())
                && Objects.equals(a1.getType(), a2.getType())
                && Objects.equals(a1.getVersion(), a2.getVersion())
                && Objects.equals(a1.getClassifier(), a2.getClassifier())
                && Objects.equals(a1.getScope(), a2.getScope())
