BRIN, GIN, B‑Tree: полный гайд по индексам PostgreSQL для highload

Индексы есть, а запросы всё равно тормозят? Или наоборот — индексов слишком много, и они только увеличивают нагрузку на запись? Многие разработчики и администраторы баз данных попадают в ловушку: ставят B-Tree на всё подряд и надеются на лучшее. Но в highload-системах это может привести к катастрофе. В этой статье я делюсь реальным опытом работы с PostgreSQL. Статья будет полезна разработчикам, архитекторам и администраторам, которые хотят не просто «поставить индекс», а понять, как работает PostgreSQL под капотом и как проектировать базы данных, выдерживающие миллионы запросов в секунду.

У продовження попереднього поста.

Сьогодні вирішив порівняти видачу в різних пошукових системах.

Питання до Бріна: От чому пошук Brave може коректно структурувати і виводити результати пошукової видачі, а Google - ні??

А може проблема в індійських і російських асессорах, які заангажовано модерують видачу, підсовуючи свої сайти в ТОП, песимізуючи українські???

Займись будь ласка цим... Бо втрачаю повагу до Твоєї компанії.

---

Насправді, ця проблема пов'язана не тільки з моїм кейсом... Те, на чому я акцентую - це глобальна проблема. Сотні, а то й тисячі українських підприємців, власники бізнесу, фірм та компаній стикаються з тим, що роками не можуть просунути свій бізнес у пошуковику... Витрачаючи величезні кошти на це... Вони звертаються до горе-сеошників, які здирають з них по 40-50-100 тис. гривень, вони наймають дорогих райтерів, які пишуть їм насичені ключовиками тексти за журналістськими стандартами, вони звертаються до лінкбілдерів, які ще більше ускладнюють та погіршують процес, штучно нарощуючи рейтинг... Але ще більшим є їх розчарування, коли вони бачать як якась "мусорка" , сайт-фейк, випереджає їх у пошуковій системі, і Google цьому лише сприяє.... Роблячи їх невидимими.

Виникає питання: а який сенс, навіщо така пошукова система???Може пора поступитися іншим, які цінують чужу роботу? (і DuckDuckGo тут не приклад, адже агрегує їхню видачу й показує не кращі результати...)

У цьому контексті Brave Search куди об'єктивніший та справедливіший. Очевидно, що інженери заклали якийсь автоматичний алгоритм, який відштовхується насамперед від віку сайту, наявності облікових записів в соцмережах, наявності форм зворотного зв'язку та контактів, інших сигналів, тому нерелевантні результати не з'являються у топі видачі так часто, як у Google...

І взагалі, сам принцип того, що в Гуглі діють якісь адміністратори-асессори - дуже сильно б'є по заангажованості і репутації цієї пошукової системи, імхо...

Так що будемо помаленьку відмовлятися і від пошуку Google, незважаючи на те, що ним поголовно користуються українці... А він вводить їх в оману. Якось так.

P.S. Попрацював кілька годин з Brave - впринципі вражений якістю. Будь-який ключовий запит дуже точно приводить користувача до цілі. Система уникає подвійності в результатах. До прикладу слово "завантажити notepad" приведе користувача саме до оригінального сайту з Notepad++, а не безліч інших які існують та присутні в видачі. Це дуже важливий аргумент навіть з точку зору безпеки.

Українська мова стало значно краще сприйматися, ніж кілька років тому. Тоді я тестував і мені не сподобалося, окрім того потрапляли російські сайти. Тобто, движок погано розрізняв російську і українську. Поки що зараз цієї проблеми не бачу.

A new tech-friendly governor?

The California governor’s race has been a crowded field without notable frontrunners.
#Newsom had been a long-time friend of the tech industry, hosting Google’s #Page and #Brin as guests at his wedding
and referring to Salesforce chief executive Marc #Benioff as “family”.
His departure appears to have Silicon Valley fretting.

#Singleton, from the Chamber of Progress, said Newsom had long recognized “how pivotal the technology industry is in California”.

But then, late last month, Matt #Mahan, a moderate Democrat and the mayor of San Jose, announced his candidacy.

Before Mahan got involved in politics in 2020, he had a career in the tech sector.
He was an undergraduate at Harvard with Zuckerberg,
and in 2014 co-founded a startup with funding from #Conway, #Benioff and Napster co-founder Sean #Parker.

Mahan appears to be the savior the tech industry had been searching for.
Since his candidacy announcement just two weeks ago,
⚠️millions have poured into his campaign.

According to public records, he’s received donations from several venture capitalists,
along with Roblox CEO David #Baszucki, Y Combinator CEO Garry #Tan, GitHub co-founder Chris #Wanstrath, Cloudkitchen co-founder Diego #Berdakin, and Ring founder #Siminoff.

Mahan has even courted donors who helped launch companies known for working with the Trump administration,
including Palantir co-founder Joe #Lonsdale and Anduril co-founder Matt #Grimm and his wife Kimberly Grimm, according to public records.

Google’s #Brin has also backed Mahan, maxing out the limit for an individual campaign donation at $78,400.

Several of Mahan’s other tech backers also maxed out their donations.
🔥At this point, Mahan has now raised more than double the two most prominent democrats in the race, ⭐️Eric Swalwell
and ⭐️Katie Porter.

As political races and ballot measure campaigns continue to heat up across California in 2026, tech’s influence is only expected to grow.

“It’s going to be a fun session,” Singleton said. That’s for sure.”

California’s billionaires pour cash into elections as big tech seeks new allies

As Gavin Newsom departs, ultra-wealthy flex wealth and influence to fight regulation and keep the boom going

The Guardian

The “California Billionaire Tax Act”,
often referred to simply as the #billionaire #tax,
is a proposalthat would require any California resident worth more than $1bn to pay a
one-off, 5% tax on their assets to help cover education, food assistance and healthcare programs in the state.

It’s sponsored by the Service Employees International Union-United Healthcare Workers West,
and if it receives enough signatures from California voters, it will go to the ballot in November.

When the proposal was put forward at the end of last year,
many among tech’s billionaire elite threw a #tantrum.

Some opened offices or bought mansions in Florida or Texas,
vowing to leave California for good.
The fleeing rich included Palantir co-founder Peter #Thiel,
whose current net worth is $25bn;
Google co-founders Larry #Page and Sergey #Brin,
worth around $255bn and $240bn respectively;
and Donald Trump’s AI and crypto czar, David #Sacks,
whose net worth is not publicly known.

Earlier this week, the Wall Street Journal reported that Meta CEO
Mark #Zuckerberg,
worth $229bn, has also bought a property in south Florida valued between $150 and $200m.

Thiel has additionally led the charge in donating to a lobbying group, the "California Business Roundtable",
which has pledged to fight the wealth tax.

The Palantir co-founder handed over $3m to the political action committee in late December.
Other major donors include realtors, entrepreneurs and private equity firms.
James #Siminoff, who founded the camera-embedded Ring doorbell company, also donated $100,000, according to public records.

“The most powerful money in politics is to be on the no-side of a ballot measure,” said #McCuan.
“You can even pre-empt something getting to the ballot, like a billionaire’s tax,
by explaining to everyone out there that this is a bad idea for economic growth.”

Tech investors and venture capitalists have been extremely vocal in their opposition to the tax,
saying that the state will lose revenue as billionaires flee and it will hurt the state’s ability to be economically competitive.

Just this week, Chamath #Palihapitiya, a former Facebook executive and current venture capital investor, wrote
“the loss of this tax revenue was totally avoidable but is now forever”.
#Balaji #Srinivasan, an investor and former chief technology officer of Coinbase, wrote,
“the most successful tech founders of all time have now exited the failed state of California”.

Adding on, Paul #Graham, the co-founder of seed capital firm Y Combinator, wrote:
“It’s important that people like Zuck and Larry Page are willing to move in response to the proposed wealth tax.
It shows politicians what will happen if they try things like this.”

Joining the billionaires, #Newsom has pledged to fight the tax, saying it will “drive a race to the bottom” and stifle innovation as the ultra-wealthy leave.
“This will be defeated – there’s no question in my mind,” Newsom told the New York Times in January.
“I’ll do what I have to do to protect the state.”

California’s billionaires pour cash into elections as big tech seeks new allies

As Gavin Newsom departs, ultra-wealthy flex wealth and influence to fight regulation and keep the boom going

The Guardian

Rarely does the mere filing of a #ballot #initiative scramble politics in California.

But the "#Billionaires #Tax" proposal is suddenly dominating the discourse
as proponents collect signatures to place it on the November ballot
— and wealthy residents, like Google co-founders
Larry #Page and Sergey #Brin,
move their assets out of the state rather than wait to see if it will pass.

The idea of taxing billionaires’ total assets
— a more aggressive idea than the income taxes California already levies on high earners
— has long captivated the left,
galvanizing labor and shaping presidential politics.

But now that
SEIU-UHW,
a union representing more than 100,000 health care workers,
has pushed the idea closer to reality than ever before,
California is getting a vivid glimpse of just how politically explosive the proposal is
and, for supporters, how high the stakes are for getting it right

The fight has reignited a struggle over the Democratic Party’s economic agenda in the runup to the 2028 presidential contest,
-- drawing vehement denunciations from Governor #Newsom and prominent Democratic donors like Reid #Hoffman

-- while being embraced by progressives like Ro #Khanna,
who represents Silicon Valley and is also mulling a presidential run.

Sen. Bernie #Sanders called it “a model that should be emulated throughout the country.”

“This isn’t radical. This is fairly simple. We live in the wealthiest country in the world and people are struggling,”
Liz #Perlman, executive director of AFSCME 3299, said on a call this week in which unions and progressive groups from around the country trumpeted higher taxes in all 50 states.

But beyond Perlman, the unions on that call did not necessarily embrace a wealth tax. And even Democrats championing populist economic messages are treading cautiously on this particular wealth tax proposal.

California Sen. Adam #Schiff, for example, signed onto a letter this week encouraging Democrats to “demonstrate a real willingness to take on corporate power and the billionaires” in advance of the midterms.

But Schiff has not yet taken a position on the proposal roiling politics in his home state.

Seit Donald Trumps Amtseinführung haben US-#Milliardäre insgesamt 415 Milliarden Dollar verloren, während die #Börsenkurse einbrachen.

Besonders getroffen wurde #ElonMusk, dessen Vermögen aufgrund sinkender #Tesla-Verkaufszahlen um 104 Mrd. Dollar geschrumpft ist.

Auch andere Tech-Milliardäre wie Jeff #Bezos, Sergey #Brin und Mark #Zuckerberg gehören zu den Verlierern.
Hauptgründe: Unsicherheit durch #Zölle, eine drohende #Trumpcession und wirtschaftliche Abschwächung.
