+# Apache ZooKeeper
+
+This directory contains a brief introduction into Apache ZooKeeper.
+
+
+## Building the presentation
+
+By running the following command, you can generate the presentation:
+
+ mvn clean package
+
+## Running the presentation
+
+In order to start a local web server serving the presentation, execute the
following command:
+
+ mvn jetty:run-exploded
+
+As soon as that's done, just point your browser to:
+
+ http://localhost:8080/
+
+## Generating PDF versions
+
+In order to generate a PDF version of the presentation just add `?print-pdf`
to the url. (Keep in mind, that you have to add it before any `#blahblah`)
+
+The following link should do the trick:
+
+ http://localhost:8080/?print-pdf
+
+As soon as that's loaded, just use the normal `print` functionality of the
browser and `print as PDF`.

+== Apache ZooKeeper
+:description: Kurzeinführung in Apache ZooKeeper
+:keywords: Apache ZooKeeper
+
+image::http://www.apache.org/logos/res/zookeeper/zookeeper.png[]
+
+
+== Einführung
+
+ZooKeeper ist ein verteilter, hochverfügbarer, skalierbarer und strikt
konsistenter data store
+
+
+== Einführung
+* Aktuelle Version ist 3.5.5 (Mai 2019)
+** Veröffentlicht nach fünf Jahren Entwicklungszeit
+** Wichtige neue Features: Dynamic Reconfiguration, "container" znode und mehr
+* Eines der erste Tools aus dem Hadoop Ökosystem
+* Ursprünglich bei Yahoo! gebaut, nun ein Apache Projekt
+
+
+== Use Cases
+* Wird von vielen Tools aus dem Hadoop Ökosystem genutzt
+** HA (HBase, YARN, Hive, …)
+** Koordination (HBase, ...)
+* "Rezepte", die einfach mit ZooKeeper zu implementieren sind:
+** Group Membership, Name Service, Configuration, Barriers, Queues, Locks,
Leader Election, Two-phased commit
+* Während ZooKeeper im Hadoop Ökosystem entstanden ist, wird es heute viel
außerhalb genutzt
+** z.B. Solr und andere Tools
+
+
+== Data Model
+image::data-model.png[]
+
+
+== Data Model
+* Hierarchie von "nodes" (znode genannt)
+** Ähnlich wie in Dateisystemen
+* Jeder znode kann sowohl andere Nodes als Kinder haben als auch Daten
+** Dies ist anders als in herkömmlichen Dateisystemen wo ein Knoten *entweder*
eine Datei *oder* ein Verzeichnis ist
+** Die Daten in einem Knoten sind normalerweise klein
+** Im Bereich weniger Kilobyte
+
+
+== Data Model
+* Alle Updates sind streng geordnet und nur ein einzelner Master Prozess
schreibt Daten, daher ist ZooKeeper nicht als data store für hohes
Transaktionsvolumen ausgelegt
+* ZooKeeper kennt mehrere verschiedene Arten von Nodes
+* Eine Verbindung zu ZooKeeper wird "session"genannt und bekommt auch eine Id
+** Verbindungsaufbau ist relativ teuer, da er auch eine Wahl/ein Quorum
erfordert
+* Man kann ein "Watch" auf ein ZNode setzen und bekommt dann eine
Benachrichtigung wenn sich einer ändert
+
+
+== Nodetypen
+* Ephemeral Nodes
+** Werden automatisch gelöscht wenn die Session geschlossen wird in der sie
erstellt wurden
+** Kann benutzt werden um verfügbare Server zu überwachen
+* Persistent Nodes
+** Diese werden nicht gelöscht wenn die Session endet
+
+
+== Nodetypen
+* Time to live (TTL) nodes (seit 3.5)
+** Wenn ein Node erstellt wird kann ein TTL Wert (in ms) angegeben werden
+** Wenn der Node nicht innerhalb des TTL Zeitraums geändert wird und er keine
children hat, kann er automatisch gelöscht werden
+* Container Nodes
+** Wenn alle child nodes gelöscht wurden kann der Container Node selbst auch
automatisch gelcöscht werden
+
+
+== Nodetypen
+* Ephemeral, Persistent und TTL Nodes können zusätzlich _sequential_ sein
+** Das fügt automatisch eine monoton ansteigende Zahl ans Ende des Node namens
an
+
+
+== Implementation Details
+* ZooKeeper benutzt ein wire protocol basierend auf einer Bibliothek namens
"Jute"
+** Ursrprünglich aus Hadoop extrahiert
+** Nicht außerhalb von ZooKeeper verwendet
+* Es gibt native Clients für C und Java
+** Andere (z.b. Python) werden von der Community verwaltetOther (e.g. Python)
+* Apache Curator ist eine Java basierte Client Library, die häufig zum Zugriff
verwendet wird da sie high level Konzepte in ihrer API anbietet
+
+
+== Zab Protocol
+* ZooKeeper ist ein verteiltes System um Daten zu speichern
+* Es braucht einen Weg damit sich mehrere Server auf Änderungen an Daten
einigen können
+* Das ist wo das "Zab" Protokoll ins Spiel kommt
+
+
+== Zab Protocol
+* ZooKeeper kann mehrere Server verwenden, dies nennt sich "Ensemble"
+* _Zab_ ist ein Algorithmus um zuverlässige Lieferungen und totale und kausale
Reihenfolge von Nachrichten zu bieten trotz unzuverlässiger Netzwerke
+* In einem Ensemble gibt es höchstens einen Leader welcher unterstüttz wird
von einer Mehrheit (ein Quorum) an Followern
+
+
+== Stimmen / Votes
+* ZooKeeper benutzt den Begriff _vote_ was eine Wahlmöglichkeit unterstellt
+* In Wirklichkeit haben Server keine Wahl sondern müssen nur Änderungen
bestätigen
+* Das ist ähnlich zu two-phase-commit Protokollen
+
+
+== Exkurs: Quorum
+* ZooKeeper basiert stark auf dem Konzept eines "Quorum"
+* Es gibt zwei Implementierungen um das Quorum festzustellen
+** Majority
+** Hierarchical
+
+
+== Exkurs: Majority Quorum
+* Der Default und sehr einfach
+* Alle voting server haben eine Stimme
+** Nicht alle Server wählen (mehr dazu später)
+* Quorum ist erreicht wenn mehr als die Hälfte (Mehrheit) der Voter einen
Schreibvorgang bestätigt haben (gewählt haben)
+* Beispiel: Ein Ensemble von 9 voting servern benötigt Stimmen von 5 Servern
um erfolgreich zu sein
+
+
+== Exkurs: Hierarchical Quorum
+* Servers gehören einer Gruppe an und haben ein Gewicht
+* Quorum ist erreicht wenn für die Mehrheit aller Gruppen jeweils mehr als die
Hälfte des totalen Gewichts (pro Gruppe) gewählt hat
+* Beispiel:
+** 9 server, 3 Gruppen, Gewicht von 1 für jeden Server
+** Quorum erfordert die Mehrheit in zwei Gruppen
+** Jede Gruppe benötigt ein Gewicht von 2 (also 2 Server) um Quorum zu
erreichen
+** Insgesamt sind 4 Votes nötig um Quorum zu erreichen
+
+
+== Sidebar: Hierarchical Quorum
+* Ein kaum benutztes Features
+* Mehr Informationen gibt es in
https://issues.apache.org/jira/browse/ZOOKEEPER-29[ZOOKEEPER-29]
+* Die ursprüngliche Idee war, dass dieses Feature zu nutzen wenn Cluster über
mehrere (phyische) Standorte verteilt sind unter der Annahme, dass Fehler eher
mit einem Standort als mit einer einzelnen Instanz korrelieren
+
+
+== Zab Protocol
+* Alle mitwählenden Server wählen einen Leader
+** Leader ist derjenige mit den meisten Stimmen (Quorum)
+** Daher meist eine ungerade Anzahl an Servern
+* Alle Servers können Read requests beantworten aber alle Schreibrequests
werden an den Leader weitergeleitet
+** Clients können trotzdem mit einem beliebigen Server sprechen (ohne seine
Rolle zu kennen), die Requests werden automatisch weiter geleitete
+
+
+== Scaling
+* Alle Datenänderungen werden zur Wahl gestellt (koordiniert vom Leader)
+* Je mehr Server es gibt desto länger dauert dieser Prozess
+* Daher gibt es das Konzept von "participants"und "observern"
+** Participants wählen mit
+** Observer nehmen nicht aktiv an der Wahl teil sondern hören nur auf das
Ergebnis
+* Das erlaubt es ZooKeeper einfach zu skalieren ohne auf Performanzeinbusse
hinzunehmen
+
+
+== Scaling
+* Dynamic Reconfiguration
+** Vor 3.5 waren die Mitgliedschafen in einem Ensemble statisch, ein Neustart
war erforderlich um das zu ändern
+** Ab Version 3.5 kann dies (und viel mehr) dynamisch geändert werden ohne,
dass ein Neustart erforderlich ist

+== Apache ZooKeeper
+:description: Brief introduction to Apache ZooKeeper
+:keywords: Apache ZooKeeper
+
+image::http://www.apache.org/logos/res/zookeeper/zookeeper.png[]
+
+
+== Introduction
+
+ZooKeeper is a distributed, highly available, scalable and strictly consistent
hierarchical data store
+
+
+== Introduction
+* Current version is 3.5.5 (May 2019)
+** Released after five years of development
+** Major new features: Dynamic Reconfiguration, "container" znode, more later
+* Other maintained branch is 3.4 with 3.4.14 (April 2019)
+* One of the first tools from the Hadoop ecosystem
+* Built at Yahoo!, now an Apache project
+
+
+== Use Cases
+* Foundation for many features in the Hadoop ecosystem
+** HA (HBase, YARN, Hive, …)
+** Coordination (HBase, ...)
+* "Recipes" easily implemented using ZooKeeper:
+** Group Membership, Name Service, Configuration, Barriers, Queues, Locks,
Leader Election, Two-phased commit
+* While ZooKeeper originated within the Hadoop ecosystem it is used heavily
outside of it as well
+** e.g. Solr and others
+
+
+== Data Model
+image::data-model.png[]
+
+
+== Data Model
+* Hierarchy of nodes (called znode)
+** Similar to typical file systems
+* Each node can "contain" other nodes as well as data
+** Different from file systems where a node is *either* a file *or* a directory
+* Data in a node is usually small
+** In the kilobyte range
+
+
+== Data Model
+* As all updates are strictly ordered, and only a single master process
performs writes, ZooKeeper is not meant as a high-volume data
+* ZooKeeper knows several different types of nodes
+* A connection to ZooKeeper is called a "session" and is also assigned an id
+** Connection setup is relatively expensive because it also requires a
quorum/vote
+* znodes can be watched (i.e. notifications on changes)
+
+== Node Types
+* Ephemeral nodes
+** Ephemeral nodes get deleted automatically once the session is closed in
which it was created
+** Can be used to get notified of failed servers (using watches)
+* Persistent nodes
+** These will not be deleted when the session ends
+
+
+== Node Types
+* Time to live (TTL) nodes (as of 3.5)
+** When creating a node a TTL value (in ms) can be specified
+** When the node has not been modified within the TTL and there are no
children it may also be deleted automatically
+* Container nodes (as of 3.5)
+** When all child nodes have been deleted the container node may also be
deleted automatically at some point
+
+
+== Node Types
+* Ephemeral, Persistent and TTL nodes can additionally be _sequential_
+** This will automatically append a monotonically increasing number to the end
of the node name
+
+
+== Implementation Details
+* ZooKeeper uses a wire protocol based on a library called "Jute"
+** Extracted from Hadoop
+** Not used outside of ZooKeeper
+* There are native clients for C and Java
+** Other (e.g. Python) clients maintained by the community
+* Apache Curator is a Java based client library that is often easier to use
than the native one as it offers higher level concepts
+
+
+== Zab Protocol
+* ZooKeeper is a distributed system to store data
+* It needs a way for multiple servers to agree on any changes to the data/state
+* This is where the "Zab" protocol comes in
+
+
+== Zab Protocol
+* ZooKeeper can use multiple servers in what's called an "Ensemble"
+* Zab is an algorithm to guarantee reliable delivery, total and causal order
of messages in the face of unreliable networks
+** To put it differently: It is a protocol for a bunch of servers to agree on
a value
+* In an ensemble there is at most one leader server supported by a quorum
+
+
+== On Votes
+* ZooKeeper sometimes uses the term _vote_ which implies a choice
+* In reality the servers don't have a choice but just need to acknowledge a
change
+* This is similar to a two-phase-commit protocol
+
+
+== Sidebar: Quorum
+* ZooKeeper is heavily based on the concept of a "quorum"
+* It has two implementations to determine the quorum
+** Majority
+** Hierarchical
+
+
+== Sidebar: Majority Quorum
+* This is the default and pretty simple
+* All voting servers get one vote
+** Not all servers vote (more on this later)
+* Quorum is achieved once more than half (i.e. majority) of the voters have
acknowledged a write
+* Example: An ensemble of 9 voting servers requires votes from 5 of those
servers to succeed
+
+
+== Sidebar: Hierarchical Quorum
+* Servers can belong to a group
+* And servers have a weight (default: 1)
+* Quorum is obtained when we get more than half of the total weight of a group
for a majority of groups
+** Example:
+*** 9 servers, 3 groups, weight of 1 for each
+*** This requires two group majorities to obtain quorum
+*** Each group requires a weight of 2 (i.e. 2 servers) to achieve quorum
+*** In total 4 votes are required to achieve quorum
+
+
+== Sidebar: Hierarchical Quorum
+* This is a rarely used feature
+* More information can be found in
https://issues.apache.org/jira/browse/ZOOKEEPER-29[ZOOKEEPER-29]
+* The original idea was to use this across (physical) locations on the
assumption that failures were more likely to be correlated with a location
going down than a single instance
+
+
+== Zab Protocol
+* All voting servers elect a leader
+** Leader is the one with the most votes (i.e. majority or quorum)
+** For this reason usually an odd number of servers
+* All servers can serve read requests but all write requests are forwarded to
the Leader
+** Clients can talk to any server (without having to know its current role),
requests are forwarded appropriately
+
+
+== Scaling
+* All changes in the system are voted upon (coordinated by the Leader)
+* The more servers there are the longer this process takes
+* Hence the concept of "participants" and "observers" exists
+** Participant servers take part in votes
+** Observers are non-voting member which only hear the results of votes
+* This allows ZooKeeper to scale more easily without sacrificing performance
+
+
+== Scaling
+* Dynamic Reconfiguration
+** Before 3.5 the membership of the ensemble and all configuration parameters
were static, a restart was required to change this
+** Starting in 3.5 this (and more) can be changed dynamically without
requiring restarts
