Я, кстати, искал примеры живых данных в формате Parquet которые бы публиковались целенаправленно как открытые данные и таки нашёл.

Проект Open Performance Data Initiative (OPDI) [1] создан Евроконтролем в 2022 году для публикации данных об эффективности управления воздушным трафиком.

Данные на портале публикуются в виде Parquet файлов [2], с интервалами дат и инструкцией по их автоматической загрузке. По сути симуляция API.

Причём данных там немало. Данные о событиях за 10 дней собираются в Parquet файл размером до 150МБ что с учётом сжатия формата хранения раскрывается в сотни миллионов значений за три года.

Under the Sebi Act, the regulator has the power to carry out search and seizure of books, registers, documents including electronics and digital devices from any person associated with the securities market. At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup. Apparently upbeat developments in Russia's discussions with Ukraine helped at least temporarily send investors back into risk assets. Russian President Vladimir Putin said during a meeting with his Belarusian counterpart Alexander Lukashenko that there were "certain positive developments" occurring in the talks with Ukraine, according to a transcript of their meeting. Putin added that discussions were happening "almost on a daily basis." The next bit isn’t clear, but Durov reportedly claimed that his resignation, dated March 21st, was an April Fools’ prank. TechCrunch implies that it was a matter of principle, but it’s hard to be clear on the wheres, whos and whys. Similarly, on April 17th, the Moscow Times quoted Durov as saying that he quit the company after being pressured to reveal account details about Ukrainians protesting the then-president Viktor Yanukovych. "Russians are really disconnected from the reality of what happening to their country," Andrey said. "So Telegram has become essential for understanding what's going on to the Russian-speaking world."
