Try to find out why Orleans need a DeathVoteExpirationTimeout config.
DeathVoteExpirationTimeout - Expiration time in seconds for death vote in the membership table. Default is 120 seconds
GetFreshVotes
DeathVoteExpirationTimeout is only used by GetFreshVotes(), which has 3 occurence:
class ClusterHealthMonitor
{
...
private UpdateMonitoredSilos(...)
{
...
bool isSuspected = candidateEntry.GetFreshVotes(now, DeathVoteExpirationTimeout).Count > 0;
...
}
}
class LocalSiloHealthMonitor
{
...
private int CheckSuspectingNodes(DateTime now, List<string> complaints)
{
...
var freshVotes = membershipEntry.GetFreshVotes(now, DeathVoteExpirationTimeout);
...
}
...
}
class MembershipTableManager
{
...
public TryToSuspectOrKill(SiloAddress silo)
{
...
// get all valid (non-expired) votes
var freshVotes = entry.GetFreshVotes(DateTime.UtcNow, DeathVoteExpirationTimeout);
...
}
...
}
GetFreshVotes() uses this expiration time to ignore old voter:
internal GetFreshVotes(DateTime now, TimeSpan expiration)
{
...
foreach (var voter in this.SuspectTimes)
{
var otherVoterTime = voter.Item2;
if (now.Subtract(otherVoterTime) < expiration)
{
result.Add(voter);
}
}
return result.ToImmutable();
}

GitExtension is a good tool. After a long time of usage, my branch list finally reaches over a full screen, and it is hard to select the branch I want.
GitExtension always remembers all the branches of remote and local, even they have been deleted.
I tried to find a way to delete these branches which are already merged, but resulted in futile.
It has a plugin names "Delete obsolete branches", but I don't know how to use it.
Finally I renamed the work directory, and cloned a new one, which clears all the branches. It seems that these branches are stored in local .git directory. If let GitExt open the renamed directory, these branches reappears.

When deployed to a cluster of nodes, Orleans internally implements a protocol to manage it's silos, including discovery, failure and reconfigure, which is called cluster membership management.
Orleans has clustering membership providers for: Azure, SQL server, Zookeeper.
Clustering provider is one of key aspects of silo configuration.
Orleans.Clustering.Kubernetes
OrleansContrib/Orleans.Clustering.Kubernetes is a clustering provider for running Orleans cluster on Kubernetes.
Tell silo to use Kubernetes as the Cluster Membership Provider:
var silo = new SiloBuilder()
...
.UseKubeMembership()
...
.Build();
Interface
UseKubeMembership() instantiates a KubeMembershipTable which implements
IMembershipTable.
public interface IMembershipTable
{
Task InitializeMembershipTable(bool tryInitTableVersion);
Task DeleteMembershipTableEntries(string clusterId);
Task CleanupDefunctSiloEntries(DateTimeOffset beforeDate);
Task<MembershipTableData> ReadRow(SiloAddress key);
Task<MembershipTableData> ReadAll();
Task<bool> InsertRow(MembershipEntry entry, TableVersion tableVersion);
Task<bool> UpdateRow(MembershipEntry entry, string etag, TableVersion tableVersion);
Task UpdateIAmAlive(MembershipEntry entry);
}
Implement
KubeMembershipTable
access Kubernetes API server to read and write silo entry CRD.
InitializeMembershipTable()
TryInitClusterVersion()
- _kubeClient.GetNamespacedCustomObjectAsync
- _kubeClient.CreateNamespacedCustomObjectAsync
DeleteMembershipTableEntries(string clusterId)
- _kubeClient.DeleteNamespacedCustomObjectAsync
InsertRow(...)
- _kubeClient.GetNamespacedCustomObjectAsync
- _kubeClient.ReplaceNamespacedCustomObjectAsync
- _kubeClient.CreateNamespacedCustomObjectAsync

- _kubeClient.ReplaceNamespacedCustomObjectAsync
UpdateRow(...)
- _kubeClient.ReplaceNamespacedCustomObjectAsync
CleanupDefunctSiloEntries(DateTimeOffset beforeDate)
- _kubeClient.DeleteNamespacedCustomObjectAsync
The operators to NamespacedCustomObject are:
- Delete
- Get
- Create
- Replace
- List
CRD
Two CRDs, ClusterVersion and Silo are defined in files:
- ClusterVersionCRD.yaml
- SiloEntryCRD.yaml
Custom resource objects are stored in etcd of Kubernetes.

Virtual Actor is a concept invented by Microsoft Orleans, which is a framework of distributed actor.
Orleans: Distributed Virtual Actors for Programmability and Scalability describes the virtual programming model.
The virtual actor is analogous to virtual memory. Virtual actors are mapped to physical arctors instances in the running servers. Virtualization of actors in Orleans has 4 facets:
-
Perpetual existence
- Actors always exist, virtually
- Actors can not be created or destroied explicitly
- Server failure does not affect the actors' existence
-
Automatic instantiation
- Activation: Orleans automatically create an actor
- A request triggers an activation if the actor doesn't exist
- Unused actors are automatically reclaimed
-
Location transparency
- Applications don't know where the physical actor is
- Similar to virtual memory's "paged out" and mapping
-
Automatic scale out
-
2 activation modes:
-
Single activation (default): Only one simultaneous actor is allowed
-
Stateless worker: Many activations of an actor are created
- to increase throughput
-
-
Actor viruliaztion greatly simplifes the programming, since it gets rid of the burden of actor lifecycle control.

Reading "The Evolution of Distributed Systems on Kubernetes" from Bilgin Ibryam.
https://www.infoq.com/articles/distributed-systems-kubernetes/
What are the purpose of projects like Dapr, Istio, Knative? How can they change the world?
Modern distributed systems
The needs of distributed systems:
Business logic
Other
- Lifecycle: deploy, rollback, upgrade, scale, stop, isolate, config
- Network: connect, circuit break, retry, timeout, load balance, discover, security, trace
- Resource binding: to API, protocol, message, data format
- State: stateless, stateful, store
Monolithic architecture
enterprise service bus (ESB): not distributed
Cloud-native architecture
Kubernetes: Lifecycle
Service Mesh
Istio: Networking
Serverless
Knative: scale
Dapr
Networking, resource binding, state
Trends
- Lifecycle: Kubernetes + operator
- Networking: Envoy
- Binding: Apache Camel
- State: Cloudstate
Multi-runtime microservice
Write business logic as another runtime. Here runtime is a process?
What comes after microservice
Faas is not the best. Multi-runtime microservice maybe is.

pub(in path), pub(crate), pub(super), and pub(self)
In addition to public and private, Rust allows users to declare an item as visible only within a given scope. The rules for pub restrictions are as follows:
pub(in path)makes an item visible within the providedpath.pathmust be an ancestor module of the item whose visibility is being declared.pub(crate)makes an item visible within the current crate.pub(super)makes an item visible to the parent module. This is equivalent topub(in super).pub(self)makes an item visible to the current module. This is equivalent topub(in self)or not usingpubat all.

# Why does Rust check borrow even in single thread
(Jin Qing's Column, Aug. 7, 2021)
The Rust book says borrow checking is to prevent data race.
But the borrow checker forbids multiply mutable borrows even in the same thread.
Is there data race in single thread?
Why does the borrow checker forbid it in the same thread?
[The Problem With Single-threaded Shared Mutability](https://manishearth.github.io/blog/2015/05/17/the-problem-with-shared-mutability/)
answers this question.
It gaves 2 cases that shared mutability causes prolem.
One is Rust enum variable, which can has different inner type.
If the inner type changed, the references to the old data would be invalidated.
Another case is Iterator invalidation that the container's change can invalidate the Iterator.

How to do multiple actions on Event BeginPlay in UE4 Blueprints?
Sams-Teach-Yourself-Unreal-Engine-4-Game-Development-in-24-Hours says:
```
Q. When I try to add a second event node, BeginPlay, the Editor shows me the first one already
placed in the Event Graph. Why does this happen?
A. Some events, such as Event Tick and the BeginPlay event, can have only one instance per
Blueprint.
```
https://forums.unrealengine.com/t/do-multiple-things-on-event-begin-play/411/10
```
The Sequence node allows for a single execution pulse to trigger a series of events in order. The node may have any number of outputs, all of which get called as soon as the Sequence node receives an input. They will always get called in order, but without any delay. To a typical user, the outputs will likely appear to have been triggered simultaneously.
