# Istio operator code overview

## Introduction

This document covers primarily the code, with some background on how the design maps to it.
See the
[design doc](https://docs.google.com/document/d/11j9ZtYWNWnxQYnZy8ayZav1FMwTH6F6z6fkDYZ7V298/edit#heading=h.qex63c29z2to)
for a more complete design description. The operator code is divided roughly into five areas:

1. [IstioOperatorSpec API](#istiooperatorspec-api) and related infrastructure, which is expressed as a

	ReplicationTimestamp time.Time
	Checksum             []byte

// MultipartInfo captures metadata information about the uploadId
// this data structure is used primarily for some internal purposes
// for verifying upload type such as was the upload
// - encrypted
// - compressed
type MultipartInfo struct {
	// Name of the bucket.
	Bucket string

	// Name of the object.

		select {
		case <-ctx.Done():
			// Retry was canceled successfully.
			return fmt.Errorf("Initializing sub-systems stopped gracefully %w", ctx.Err())
		default:
		}

		// These messages only meant primarily for distributed setup, so only log during distributed setup.
		if globalIsDistErasure {
			logger.Info("Waiting for all MinIO sub-systems to be initialize...")
		}

Primarily for historical reasons, ingestion is split into a few components.

#### ConfigStore

Instead, the rich functionality that service mesh is traditionally associated with is deferred to the waypoints.
The ztunnel is primarily a mechanism to get traffic to the waypoints, securely.
