Нагрузочное тестирование динамического маскирования в Apache Ranger: что происходит с производительностью запросов

Привет, Хабр! На связи Илья Амосов из команды поддержки Lakehouse-платформы данных Data Ocean Nova вендора Data Sapience. В сегодняшней публикации я раскрою тему влияния динамического сокрытия чувствительных данных на производительность SQL-запросов. Мы сравним различные методики маскирования, узнаем, как работает оптимизатор и движок со скрытыми полями, происходит ли деградация пропускной способности платформы, как влияет на производительность выбранный метод сокрытия чувствительных данных в случаях, если вы используете компонент на базе Apache Ranger.

Epic Battle

(Description by Loupy)

"What are we playing today?" asked Bluey as Bingo's classmates Snow the pisse-lit (bedwetter in French, as how Loupy got people to call him alternatively with plush) pizzly and Loupy were over to play with the two sisters and Fiona, Loupy's adoptive older sister which was one year older.
"We could be the heroes from stories! Our parents plays Dungeons & Dragons and showed us some stuff about it!" said Fiona.
"That sound really fun." said Bingo. "It's like those knight's stories..."

Half hour later, the kids were all dressed up in improvised costumes. Bluey was a knight, dressed in shiny aluminum foil and cardboard armor, Bingo was a mage with a fairy wand and costume, Fiona was a barbarian with her diaper barely covered by something and a plastic axe. Snow was carrying a weird cardboard tube and was colouring flames to add to said tube.
"I'm an artificer!" said the ursine. "I have a big canon to blow everything up."
"Your diaper sure blows up often." said Loupy while he confused people with his bow, struggling to find his glasses.
"Are you a ranger?" asked Bluey.
"I'm a bard... they tend to use bows too, I sing instead of having a pet plush, since Snow didn't wanted to be the pet..." answered the wolf.
"Pleawse don't sing." said Fiona. Her brother bowed like a performer as his only answer.

"We are facing the plush servants of the Potty Monster, plush. Hope you got something to push through." said the bard princess (title given to him by Bluey).
"I have something right here... just hope I remember the splash zone..." answered ominously the bear.

Dark and Darker devs fling open the gates to Inferno, proper HELL for thrill‑seekers 🔥

The Forgotten Castle got a full third floor overhaul: Inferno is deadlier and way more atmospheric; Ranger and Rogue received new skills and perks; Squire Royale was reworked into a tense, faster BR. New ping system and LFG tool ease coordination, devs warn the opening of Inferno will be a serious test even for vets.

Bähm! Gerade einem #Glasfaser-Drücker von #Ranger die Tür vor der Nase zugeschlagen. Jetzt tut mir die Tür ein bisschen leid.

Im Ernst: Die stehen hier zum ungezählten Mal, mindestens fünfmal so oft wie die Zeugen Jehovas, vor der Tür und erzählen die Mär vom baldigen Abschalten des Internets und/oder von teuren Kabelverlegungen, falls ich nicht sofort unterschreibe. Ekelhafter Laden.

FTTB haben wir längst im Haus. FTTH will die WEG nicht.
