A Cross-Country and Cross-Wikipedia Comparison We compare the number of biographies by birth year and country against demographic birth data to estimate the probability of appearing in different Wikipedia language editions, depending on one's country of birth. Research Questions What is the probability of having a biography in different Wikipedia language editions? Does country of birth affect this probability? If so, which birth countries are most overrepresented on Wikipedia? Do different Wikipedia editio

Parquet gave data lakes a common language: columnar layout, good compression, and fast scans. That still works well for classic analytics. But workloads have changed. We now mix wide scans with point lookups, handle embeddings and images, and run on S3-first stacks. On NVMe you want lots of tiny random reads. On S3 you want fewer, larger range requests. A format tuned for one world can feel chatty or slow in the other.
Гайд: Как работать с форматом PARQUET
В прошлом году мы начали публиковать данные в каталоге «Если быть точным» в формате Parquet . Его придумали инженеры Twitter и Cloudera в 2013 году, и сегодня он стал стандартом хранения аналитических данных — его используют Google, Amazon, Netflix и большинство современных data-платформ. В этом гайде мы расскажем, как эффективно работать с данными в формате Parquet с помощью Python.
