Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.

Spark is the widely used ETL tool for processing, indexing and ingesting data to serving stack for search. Milvus is the production-ready open-source vector database. In this talk we will show how to use Spark to process unstructured data to extract vector representations, and push the vectors to Milvus vector database for search serving.

4. Ресурсы: зачем контролировать?
Ресурсы не бесконечны
•
Сервер один, задач и пользователей много
•
Нужна статистика по использованию
•
Нужна защита от DoS атак
•
Нужно обеспечить качество сервиса
•
– не только лимиты, но и гарантии
5. Ресурсы: что контролировать?
Процессор
•
Оперативная память и подкачка (swap)
•
Дисковое пространство
•
Дисковый ввод-вывод (I/O bandwidth)
•
Сеть (сокеты, буфера, bandwidth и т.п.)
•
Прочее
•
6. Процессор
Процессорное время раздаётся процессам
маленькими временными отрезками
• Приоритеты (веса)
• Ограничения сверху (лимиты)
• Привязка к конкретным процессорам
(для многопроцессорных систем)
7. Оперативная память
• Память уровня пользователя
– Виртуальная (VM) и физическая (RSS)
– page cache
• Память ядра
– Различные объекты / механизмы выделения
– Особый случай: сетевые буфера
• Пространство подкачки (swap)
8. Диск
• Место
• Пропускная способность ввода-вывода
– Чтение и запись
– Отображения памяти (mmap)
– Подкачка (swapin/swapout)
• Статистика ввода-вывода
9. Сеть
• Тут всё уже решено, говорить не о чем
– ...более или менее
• TC: traffic control
– Шейпинг, шедалинг, политики, ...
• iptables

11. Контейнеры — это ...
• такая легковесная виртуализация
• много контейнеров поверх единого ядра
• совсем как VM, только
– одна ОС (хотя м.б. разные дистрибутивы)
– «родная» производительность
– высокая плотность размещения
– динамическое управление ресурсами
13. HP labs: OpenVZ vs Xen
• Накладные расходы Xen больше
• Накладными расходами OpenVZ
зачастую можно пренебречь
• Под Xen работало 4 копии интернет-
магазина и сервер уже был перегружен,
под OpenVZ заработало 6 без перегрузки
15. Контейнеры
и управление ресурсами
• Обеспечить мирное сосуществование
множества контейнеров
• С точки зрения управления ресурсами,
контейнеры — это просто группы
процессов!

17. Процессор
• Каждый процесс имеет nice value,
можно менять «по дороге» (nice/renice)
• Есть приоритет реального времени и
отдельная очередь процессов для него
• Жёсткий лимит на процессорное время
процесса (ulimit -c)
18. Место на диске
• Стандартные UNIX квоты очень хороши
– квоты на точку монтирования
– для пользователей и для групп
– мягкие и жёсткие лимиты, грейс-период
– можно узнать текущие значения
– можно менять лимиты «по дороге»
– приложения ожидают отказов (или должны)
19. Всё остальное: ulimit
• Реализован системными вызовами
setrlimit() и getrlimit()
• Контролирует 16 разных параметров:
core file size, data segment size, scheduling priority, file size, pending signals,
max locked memory, max memory size, number of open files, pipe size,
POSIX message queues, real-time priority, stack size, cpu time, max user processes,
virtual memory, file locks
• Есть «мягкие» и «жёсткие» лимиты
20. ulimit
$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 38400
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 1024
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
21. У ulimit много проблем
Далеко не все ресурсы учитываются
•
Нельзя посмотреть текущее использование
•
Лимиты выставляются в текущем контексте
•
Все лимиты выставляются на процесс
•
– кроме NPROC, который на пользователя
• Лимиты на память в основном игнорируются

23. OpenVZ beancounters
Контролирует группы процессов
•
20 различных параметров
•
Все можно менять во время выполнения
•
Для каждого параметра можно видеть:
•
– Текущее значение, пиковое значение
– Счётчик отказов в выделении ресурса
27. Другие механизмы OpenVZ
• “Честный” планировщик процессов
– веса (приоритеты) и жёсткие лимиты
• Двухуровневая дисковая квота
– I уровень: квоты на контейнер
– II уровень: квоты внутри контейнера
• Приоритет дискового ввода-вывода

29. Control Groups aka CGroups
• Универсальный механизм для группировки
процессов в иехархические группы
• Различные контроллеры ресурсов
• Можно иметь разные группы для разных
контроллеров
• Управляется через файловую систему
30. Control Groups: управление
mkdir /dev/cgroup
mount -t cgroup none /dev/cgroup
mkdir /dev/cgroup/0
cd /dev/cgroup/0
echo $$ > tasks
cat /proc/self/cgroup
/etc/init.d/httpd start
31. Control Groups: история
• Вначале были cpusets от Bull/SGI
– Для привязки групп задач к NUMA узлам
• Paul Menage из Google разделил cpusets
на инфраструктуру (группировки) и
контроллеры
– сpusets теперь просто один из контроллеров
– можно добавлять другие
32. Memory Controller
• Контролирует память пользователя и page
cache
• Reclamation (утилизация? Переработка?)
– как в try_to_free_pages()
• Out-of-memory killer
34. Память пользователя
Длина маппингов
RSS
Адресное пространство процесса
Возвраща- Неисполь- Исполь- Невозвра-
емые VMA зуемые зуемые щаемые
(mmap'ed страницы страницы VMA
files) (private and
anon)
