#zookeeper — Public Fediverse posts

If anyone knows of any decent write-up on securing ZooKeeper / ClickHouse Keeper, I am very interested.

Documentation of both is really crap I find, and security seems to be a complete afterthought.

I would love to be proven wrong on that last bit.

Redis and ZooKeeper are widely used for distributed locking. Redis uses key expiry with a time-to-live. ZooKeeper uses ephemeral sequential nodes, where the client holding the lowest sequence number owns the lock.

Rentrer avec le single-speed et enfin descendre en dessous des 40 min pour 14 km, une petite douche parce qu'il faut un peu chaud quand même, décompresser sur le Zoo Keeper de la Nintendo en mode Top Chrono ET ENFIN EXPLOSER LES 5 MILLIONS !

Capitaine Haddock, je propose que cette semaine s'arrête maintenant.

These two were very proud of their nesting material (my best guess) and were strutting around their enclosure, showing off. You can see clearly why they are called hornbills.

BTW, are you a #zookeeper ? My wife and I volunteer at our local zoo. (You might guess I'm a photographer.)

📢 @ApacheKafka 4.0.0 is released!
The biggest news: saying goodbye to #ZooKeeper after over a decade, and making #KRaft the default mode, simplifying deployment and management.

Also new consumer group protocol, early access to Queues for #Kafka and more. Congrats! 👏

👑 Is zookeeper trully loyal to me?

The Roaring Lion

If you heard the name of the famous photograph, The Roaring Lion, and asked to see it, I’m sure you would be confused. Firstly there is no image of an actual lion in this photograph. Instead you would see a rather dour looking Winston Churchill. Hardly a lion and at 67 years old, not nearly as strong or powerful as an actual lion.

As for the roaring? Churchill isn’t even opening his mouth, let alone roaring at the photographer. Maybe he’s humming but that’s about the only sound he could make when this picture was snapped.

But in symbolism, Great Britain has long been represented by a rampant lion, particularly Scotland. This is supposed to go back to ancient times. How a lion came to represent a nation without any lions at all, is truly one of life’s big wonders. Perhaps a better symbol of Britain could be a zookeeper. They are the people that not only brought the lion to the north, but take care of it as well.

Anyhow, if Britain is a lion, then in World War II, Churchill could have been said to be its voice. So perhaps that is the explanation of the name of this portrait.

But here is the real reason for the name of the portrait. The photographer, Karsh, asked Churchill to put his cigar in an ashtray since the smoke would interfere with the photo. Churchill refused so Karsh grabbed the cigar from Churchill while asking for forgiveness. Only then did Karsh take the photos, including the famous one where Churchill is having a nicotine fit.

After the session, Winston Churchill said, “You can even make a roaring lion stand still to be photographed.” And that is the official reason for the name of the picture.

It’s interesting that this photograph, which was hung in the Fairmont Chateau Laurier in Ottawa (which is signed by Karsh) is worth millions. It was stolen from its place last year and sold for only about $10 000. It is my belief that the negative is worth the most because more photos could be made from it. Library and Archives Canada holds that and is keeping the price of prints up by promising not to make any more photographs off the negative.

You're a teenager. You're a zookeeper. It's a fantasy magical petting zoo. It's a lasers and feelings game about being a Teenage Magical Zookeeper.

A game about being potentially very useless at your summer job whilst just trying to make it to the end of the day without being set on fire, bitten, covered in slime, or yelled at by the visitors.

Дом, милый дом: нюансы работы с ClickHouse. Часть 2, репликация

Всем привет, меня зовут Пётр. В первой части этого цикла статей мы взглянули на некоторые базовые концепции ClickHouse. В этой же статье продолжим изучать тонкости работы с этой колоночной базой данных и подробно рассмотрим такой аспект как репликация. А ещё разберёмся с сервисами координации Zookeeper и ClickHouse Keeper. Давайте разбираться!

Как мы повышали производительность очереди сообщений

Работа в Яндексе ставит огромное количество технических вызовов, которые интересно решать. И один из них — это производительность основной очереди сообщений YDB Topics . Посмотрим, может ли опенсорсный продукт от Яндекса конкурировать с Apache Kafka по производительности. Меня зовут Зевайкин Александр . Я уже практически 20 лет в IT. Начинал с преподавания в вузе, запускал множество стартапов, руководил командами разработки. В текущий момент я работаю в Яндексе в отделе, занимающимся одной из высоконагруженных систем. Это разработка распределённой базы YDB , в частности, функциональности YDB Topic.
