## Configuration

To view support configuration options and documentation, run:

```console
helm show values istio/istiod
```

### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
These can be set with `--set profile=<profile>`.

import "k8s.io/apimachinery/pkg/runtime/schema/generated.proto";

// Package-wide variables from generator "generated".
option go_package = "k8s.io/api/coordination/v1";

// Lease defines a lease concept.

Istio is an open source service mesh that layers transparently onto existing distributed applications. Istio’s powerful features provide a uniform and more efficient way to secure, connect, and monitor services. Istio is the path to load balancing, service-to-service authentication, and monitoring – with few or no service code changes.

At a high level, each client job will find the correct generator for the request, generate the required configuration, and send it.

#### Optimizations

A naive implementation would simply regenerate all resources, of all subscribed types, for each client, on any configuration change. However, this scales poorly. As a result, we have many levels of optimizations to avoid doing this work.
